The drainage basins ranged in size from 3.72 to 83.4 square miles. Using the model, synthetic records of streamflow for each basin were generated to represent various degrees of urban development. Examination of the synthetic records indicated that urbanization has the following effects on streamflow in the area:
Hydrologic, digital-model, and economic analyses were made to determine the most efficient balance of conjunctive use of local ground water and surface water--specifically, whether additional ground-water supplies can be developed in the Oak Glen study area, San Bernardino County, Calif., for local use and also for export to the adjacent Yucaipa area, and what will be the effects of imported water available in 1980.
The hydrologic analysis showed that transmissivity values of the aquifer in the Oak Glen study area ranged from 1,000 to 6,750 gallons per day per foot or their equivalent 134 to 902 feet squared per day (12 to 84 metres squared per day) and that net annual recharge in the area was about 1,940 acre-feet (2.39 cubic hectometres) per year. The volume of ground water in storage in 1970 was about 86,000 acre-feet (106 cubic hectometres).
The digital-model analysis included building and verifying a steady-state and a non-steady-state model. The steady-state model was considered to be verified when the model-generated water levels approximated the measured 1949 water levels, which were assumed to represent steady-state water-level conditions. The non-steady-state model was verified for 1949-70, and the model satisfactorily reproduced the measured water-level changes for the study area during that period. Water-level changes in the ground-water basin were predicted from 1971 to 1980 using as representative average annual pumpage that from 1966 to 1970 and 1971. The model also predicted water-level changes from 1971 to 1980 using the maximum pumpage capacities of the wells under recharge conditions for average, wet, and dry periods.
The predicted water-level changes in the Oak Glen study area were used to calculate the average costs of pumping water for 1980. The comparable average costs of importing water from an alternative supply and the capital costs of well construction were also determined. The economic evaluation suggests the following: (1) Increase ground-water pumping for local use, (2) reduce well-water import to the lower parts of the Oak Glen study area from adjacent areas to the west, (3) short term prior to 1980 overdevelopment appears to be feasible with export to Yucaipa, and (4) tunnel development or new shallow wells at the higher altitudes could help alleviate the water problem.

The model was considered verified when the ground-water levels generated by the model approximated the historical change in water levels of the ground-water basin caused by man's activities for the period 1986-67. The ground-water basin was almost unaffected by man's activities until about 1945 when ground-water development caused the water levels to begin to decline. The Palm Springs area has had the largest water-level decline, 75 feet since 1986, because of large pumpage, reduced natural inflow from the San Gorgonio Pass area, and diversions of natural inflows at Snow and Falls Creeks and Chino Canyon starting in 1945. The San Gorgonio Pass inflow had been reduced from about 18,000 acre-feet in 1986 to about 9,000 acre-feet by 1967 because of increased ground-water pumpage in the San Gorgonio Pass area, dewatering of the San Gorgonio Pass area that took place when the tunnel for the Metropolitan Water District of Southern California was drilled, and diversions of surface inflow at Snow and Falls Creeks. In addition, 1944-64 was a period of below-normal precipitation which, in part, contributed to the declines in water levels in the Coachella Valley. The Desert Hot Springs, Garnet Hill, and Mission Creek subbasins have had relatively little development; consequently, the water-level declines have been small, ranging from 5 to 15 feet since 1986. In the Point Happy area a decline of about 2 feet per year continued until 1949 when delivery of Colorado River water to the lower valley through the Coachella Canal was initiated. Since 1949 the water levels in the Point Happy area have been rising and by 1967 were above their 1986 levels. \r\n\r\nThe Whitewater River subbasin includes the largest aquifer in the basin, having sustained ground-water pumpage of about 740,000 acre-feet from 1986 to 1967, and will probably continue to provide the most significant supply of ground water for the upper valley. The total ground-water storage depletion for the entire upper valley for 1986-67 was about 600,000 acre-feet, an average storage decrease of about 25,000 acre-feet per year since 1945. \r\n\r\nTransmissivity for the Whitewater River subbasin ranges from 860,000 gallons per day per foot (near Point Happy) to 50,000 gallons per day per foot, with most of the subbasin about 800,000 gallons per day per foot. In contrast, the transmissivities of the Desert Hot Springs, Mission Creek, and Garnet Hill subbasins generally range from 2,000 to 100,000, but the highest value, beneath the Mission Creek streambed deposits, is 200,000 gallons per day per foot; the transmissivity for most of the area of th6 three subbasins is 80,000 gallons per day per foot.\r\n\r\nThe storage coefficients are representative of water-table conditions, ranging from 0.18 beneath the Mission Creek stream deposits to 0.06 in the Palm Springs area. \r\n\r\nThe model indicated that the outflow at Point Happy decreased from 50,000 acre-feet in 1936 to 30,000 acre-feet by 1967 as a result of the rising water levels in the lower valley. \r\n\r\nThe most logical area to recharge the Colorado River water is the Windy Point-Whitewater area, where adequate percolation rates of 2-4 acre-feet per acre per day are probable. The Whitewater River bed may be the best location to spread the water if the largest part of the imported water can be recharged during low-flow periods. The area in sec. 21, T. 2 S., R. 4 E., would be adequate for the smaller quantities of recharge proposed for the Mission Creek area. \r\n\r\nProjected pumpage for the period 1968-2000 was programmed on the model with the proposed recharge of Colorado River water for the same period. The model indicated a maximum water-level increase of 200 feet above the 1967 water level at Windy Point, the proposed recharge site, by the year 2000, a 130-foot increase by 1990, and a 20-foot increas","language":"ENGLISH","publisher":"U.S. Govt.

(ELETROBRAS) as a part of the cooperative program of the U.S. Geological Survey (USGS) and CPRM under the auspices of the Ministerio das Minas e Energia (MME) and the U.S. Agency for International Development (USAID). Its primary purpose is to provide an evaluation of the adequacy of streamflow data on streams which are being considered for or are already being utilized for hydroelectric power sources. Some comments are included pertaining to the general coverage hydrologic network. These comments were generated by the examination of the streamflow data useful for power purposes because all gaging stations form a part of the total network for hydrologic investigations. Present plans are that the entire network will eventually be operated by or under the jurisdiction of the MME through the Departamento National de Aguas e Energia Eletrica (DNAEE).
Brazil is a large country, larger than the conterminous United States, and it has been engaged in hydrologic investigations for more than 50 years. The network has been maintained by Federal agencies, State agencies, power companies, and consulting firms and until recently no organizational mechanism existed to coordinate the various activities or to establish uniform standards of data collection, computation, and publication.
It is estimated that stage and/or discharge data have been collected at 2,500 or more sites in Brazil. Because there has been no centralized publication system, it has not been possible to locate with assurance all measurement sites or to ascertain precisely the types and quality of the data collected or available.
For these reasons the suggestions outlined in this report are expected to be modified on the basis of local need and site information, which may not have been evident at the time of the review. For example, specific suggestions have been made to discontinue some stations which appear superfluous or which essentially duplicate other stations. In other instances additions to the network have been proposed. There may be reasons for the continued operation of a given station which cannot be discerned from the available literature. Also coverage may have been established in an area but the evidence has not yet appeared in print. DEAEE is currently (1973) working diligently to overcome a backlog of data computation and publication. Brazil is currently developing at a rapid rate with electric power demands increasing at a 12% annually, a reflection of the tremendous growth of the economy. With this rate of increase likely to continue for the foreseable future, it goes without saying that hydrologic information needed tomorrow must be collected today.

The program computes the coordinates for a variable grid -used in the 'Pinder Model' (a finite-difference aquifer simulator), for input to the CalComp GPCP (general purpose contouring program). The program adjusts the y-value by a user-supplied constant in order to transpose the origin of the model grid from the upper left-hand corner to the lower left-hand corner of the grid. The user has the options of, (1.) choosing the boundaries of the plot; (2.) adjusting the z-values (altitudes) by a constant; (3.) deleting superfluous z-values and (4.) subtracting the simulated surfaces from each other to obtain the decline. Output of this program includes the fixed format CNTL data cards and the other data cards required for input to GPCP. The output from GPCP then is used to produce a potentiometric map or a decline map by means of the CalComp plotter.","language":"ENGLISH","doi":"10.3133/ofr741018","usgsCitation":"Cosner, O.J., and Horwich, E., 1974, Grid-coordinate generation program: U.S. Geological Survey Open-File Report 74-1018, 27 leaves : ill. ; 29 cm., https://doi.org/10.3133/ofr741018.","productDescription":"27 leaves : ill. ; 29 cm.","costCenters":[],"links":[{"id":172504,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1974/1018/report-thumb.jpg"},{"id":84918,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1974/1018/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":84919,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1974/1018/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":84920,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1974/1018/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ab2e4b07f02db66ed20","contributors":{"authors":[{"text":"Cosner, Oliver J.","contributorId":38533,"corporation":false,"usgs":true,"family":"Cosner","given":"Oliver","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":236997,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Horwich, Esther","contributorId":106557,"corporation":false,"usgs":true,"family":"Horwich","given":"Esther","email":"","affiliations":[],"preferred":false,"id":236998,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":12774,"text":"ofr74226 - 1974 - Economic geology of the Isla de Mona Quadrangle, Puerto Rico","interactions":[],"lastModifiedDate":"2012-02-02T00:06:33","indexId":"ofr74226","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1974","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"74-226","title":"Economic geology of the Isla de Mona Quadrangle, Puerto Rico","docAbstract":"Limiting this tableland In the northern part of Isla de Mona are sheer sea cliffs chiefly exposing the Isla de Mona Dolomite. Around the southern part of the island are Irregular cliffs and steep slopes that chiefly expose the Lirio Limestone. \r\n\r\nThe structure of Isla de Mona consists of two gentle complex folds a broad anticline that trends and plunges gently south-southeast through the central and western parts of Isla de Mona, and a parallel syncline through-the eastern part of the Island that also has a chiefly south-southeast plunge. A near-vertical fault that strikes northwest, then north from the central part to the north coast of Isla de Mona displaces bedrock of the eastern block downward about 10 m. \r\n\r\nMany caves, including one cave system more than 100,000 m2 in total area, are localized in the lower 10 m of the Lirio Limestone, adjacent to the cliffs peripheral to the upland surface, and numerous small caves occur higher in the Lirio. A few small caves also are \r\nfound In the Isla de Mona Dolomite. However, the total floor area of all caves on Isla de Mona probably is less than 1 percent of the area of the Island.\r\n\r\nAlmost all caves on Isla de Mona contain phosphorite, which was mined extensively during the late 19th and early 20th centuries. Phosphorite accumulation locally may have exceeded 3.5 m in thickness, but probably averaged less than 1.5 m thick. A fair estimate of original reserves of phosphorite in 12 surveyed caves is about 151,000 m3 of which about 125,500 m3 probably has been removed in mining. Original reserves in the entire island are estimated to have been in the range 158,000 to 235,500 m3. Converted to metric tons, remaining reserves of cave phosphorite probably are considerably less than 50,000. \r\n\r\nThe very pure limestone and calcitic dolomite that form the bedrock of Isla de Mona are abundant industrial-mineral resources.

Monitoring studies have indicated that tritium and chloride have dispersed over a 15-square mile (39-square kilometer) area of the aquifer in low but detectable concentrations and have only migrated as far as 5 miles (8 kilometers) downgradient from discharge points. The movement of cationic waste solutes, particularly 90Sr and 137Cs, has been significantly retarded due to sorption phenomena, principally ion exchange. 137Cs has shown no detectable migration in the aquifer and 90Sr has migrated only about 1.5 miles (2 kilometers) from the Idaho Chemical Processing Plant (ICPP) discharge well, and is detectable over an area of only 1.5 square miles ( 4 square kilometers) of the aquifer. Digital modeling techniques have been applied successfully to the analysis of the complex waste-transport system by utilizing numerical solution of the coupled equations of groundwater motion and mass transport. The model includes the effects of convective transport, flow divergence, two-dimensional hydraulic dispersion, radioactive decay, and reversible linear sorption. The hydraulic phase of the model uses the iterative, alternating direction, implicit finite-difference scheme to solve the groundwater flow equations, while the waste-transport phase uses a modified method of characteristics to solve the solute transport equations simulated by the model. The modeling results indicate that hydraulic dispersion (especially transverse) is a much more significant influence than previously suggested by earlier studies. The model has been used to estimate future waste migration patterns for varied assumed hydrological and waste conditions up through the year 2000. The hydraulic effects of recharge from the Big Lost River have an important (but not predominant) influence on the simulated future migration patterns. For the assumed conditions, the model indicates that detectable concentrations of waste chloride and tritium could move as much as 15 miles (24 kilometers) downgradient from the original discharge points by the year 2000. However, the model shows 90Sr moving only 2 to 3 miles (3 to 5 kilometers) downgradient in the same time. The model may also be used to estimate the effects of the various future waste disposal practices and hydrologic conditions on subsequent migration of waste products.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr741089","collaboration":"Work done in cooperation with the U.S. Atomic Energy Commission","usgsCitation":"Robertson, J., 1974, Digital modeling of radioactive and chemical waste transport in the Snake River plain aquifer at the National Reactor Testing Station, Idaho: U.S. Geological Survey Open-File Report 74-1089, vi, 41 p., https://doi.org/10.3133/ofr741089.","productDescription":"vi, 41 p.","startPage":"i","endPage":"41","numberOfPages":"47","costCenters":[{"id":634,"text":"Water Resources Program","active":false,"usgs":true}],"links":[{"id":265807,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pbadupws.nrc.gov/docs/ML0609/ML060960424.pdf"},{"id":171187,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"country":"United States","state":"Idaho","otherGeospatial":"Snake River","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -117.24,41.99 ], [ -117.24,49.0 ], [ -111.04,49.0 ], [ -111.04,41.99 ], [ -117.24,41.99 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a96e4b07f02db65aa07","contributors":{"authors":[{"text":"Robertson, J.B.","contributorId":85173,"corporation":false,"usgs":true,"family":"Robertson","given":"J.B.","email":"","affiliations":[],"preferred":false,"id":237046,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":46140,"text":"ofr74293 - 1974 - Map of land modified by man in part of the Monongahela 7 1/2-minute Quadrangle, Allegheny County and vicinity, Pennsylvania","interactions":[],"lastModifiedDate":"2012-02-02T00:10:46","indexId":"ofr74293","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1974","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"74-293","title":"Map of land modified by man in part of the Monongahela 7 1/2-minute Quadrangle, Allegheny County and vicinity, Pennsylvania","language":"ENGLISH","doi":"10.3133/ofr74293","usgsCitation":"Davies, W., 1974, Map of land modified by man in part of the Monongahela 7 1/2-minute Quadrangle, Allegheny County and vicinity, Pennsylvania: U.S. Geological Survey Open-File Report 74-293, 8 p.; 1 map, https://doi.org/10.3133/ofr74293.","productDescription":"8 p.; 1 map","costCenters":[],"links":[{"id":171394,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":83101,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1974/0293/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}}],"scale":"24000","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a92e4b07f02db6576f6","contributors":{"authors":[{"text":"Davies, W.E.","contributorId":12440,"corporation":false,"usgs":true,"family":"Davies","given":"W.E.","email":"","affiliations":[],"preferred":false,"id":232692,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":28784,"text":"wri749 - 1974 - Seawater intrusion, ground-water pumpage, ground-water yield, and artificial recharge of the Pajaro Valley area, Santa Cruz and Monterey Counties, California","interactions":[],"lastModifiedDate":"2018-10-31T13:56:49","indexId":"wri749","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1974","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":342,"text":"Water-Resources Investigations Report","code":"WRI","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"74-9","title":"Seawater intrusion, ground-water pumpage, ground-water yield, and artificial recharge of the Pajaro Valley area, Santa Cruz and Monterey Counties, California","docAbstract":"The Pajaro Valley area, California, covering about 120 square miles (310 km2), extends from the southern part of Santa Cruz County to several miles south of the county line into Monterey County. It borders the Pacific Ocean on the west and the Santa Cruz Mountains on the east. The city of Watsonville is the largest center of population.
Seawater intrusion is occurring in the Pajaro Valley area from several miles north to several miles south of the mouth of the Pajaro River and in a small area about 4 miles (6.5 km) north of the river. The intrusion extends inland about 1 mile (1.6 km). Two water-bearing zones are being intruded--the depth intervals 100-200 feet (30-60 m) and 300-600 feet (90-180 m).
Ground-water pumpage averaged 49,100 acre-feet per year (60.6 hm3/yr) for the 9-year period 1963-71. The long-term ground-water yield of the Pajaro Valley is about 44,000 acre-feet per year (54.3 hm3/yr). Artificial recharge can be effected through modified streambeds at infiltration rates as high as 3 feet per day (0.9 m/d). Injection wells may have recharge capabilities of as much as 500 gallons per minute (1.9 m3/min).

The aquifer covers about a third of the 79 mi 2 (205 km2) study area, occurring mainly in stream valleys that are less than a mi le wide. Its saturated thickness is commonly 40 to 60ft (12 to 18 m); its transmissivity is commonly 5,000 to 8,000 ft 2/day (460 to 740m2 /day). The aquifer is hydraulically connected to streams that cross it and much of the water from heavily pumped wells will consist of infiltration induced from them. Potential sustained yield from most parts of the aquifer is limited chiefly by the rate at which infiltration can be induced from streams or low streamflow, whichever is smaller. Ground-water withdrawals deplete streamflow; and if large-scale development of ground water is not carefully planned and managed, periods of no streamflow may result during dry weather. Potential sustained yield varies with the scheme of well development, and is evaluated for selected areas by mathematically simulating pumping from assumed schemes of well Is in models of the stream-aquifer system. Results indicate that sustained yields of 5.5, 3.4, 1.6, and 1.3 mgd (0.24, 0.15, 0.07, and 0.06 m3 /s) can be obtained from the stratified-drift aquifer near Slatersville, Oakland, Harrisville, and Chepachet, respectively. Pumping at these rates will not cause streams to go dry, if the water is returned to streams near points of withdrawal. A larger ground-water yield can be obtained, if periods of no streamflow along reaches of principal streams are acceptable. Inorganic chemical quality of water in the stream-aquifer system is suitable for most purposes; the water is soft, slightly acidic, and generally contains less than 100 milligrams per litre of dissolved sol ids. Continued good quality ground water depends on maintenance of good quality of water in streams, because much of the water pumped from wells will be infiltrated from streams.

The primary purpose of the study was to measure the concentration and distribution of selected primary nutrients, organic carbon, dissolved oxygen, phytoplankton, and water temperature in the lake. Estimates of the nitrogen, phosphorus, and silica loading to the lake from surface-water tributaries and precipitation were also made.
Results of the study indicate that Big Bear Lake is moderately eutrophic, at least in regard to nitrogen, phosphorus, and organic content. Nitrate was found in either trace concentrations or below detectable limits; however, ammonia nitrogen was usually detected in concentrations greater than 0.05 milligrams per liter. Orthophosphate phosphorus was detected in mean concentrations ranging from 0.01 to 0.05 milligrams per liter. Organic nitrogen and phosphorus were also detected in measurable concentrations.
Seasonal levels of dissolved oxygen indicated that the nutrients and other controlling factors were optimum for relatively high primary productivity. However, production varied both seasonally and areally in the lake. Primary productivity seemed highest in the eastern and middle parts of the lake. The middle and western parts of the lake exhibited severe oxygen deficits in the deeper water during the warmer summer months of June and July 1972.

Even though the major topographic features are controlled by the lithology and structure of the bedrock, glacial features, such as drumlins, kames and kettles, kame terraces, eskers, gently sloping deltas, and flat-lying lake-bottom deposits, have modified the preglacial topography. Some bedrock plucking occurred, especially on the south or southeast sides of some hills, and some valleys probably were deepened. A thin veneer of till overlies much of the bedrock and is most extensive in the hills in the western half of the map area. These deposits, which are mostly gently sloping kame deltas or flat-lying lake-bottom deposits, were laid down in or graded to glacial Lakes Charles (Clapp, 1904, p. 198) and Sudbury (Goldthwait, 1905, p. 274), which formed during deglaciation when melt waters were temporarily impounded. Some glacial-lake deposits were laid down in three smaller higher level lakes in the western part of the quadrangle.
\nWith the exception of a small part of the southeast corner, which is drained by the Charles River, the quadrangle is drained by the Sudbury River, whose waters eventually flow into the Merrimack River in the northeast part of the state.

An analysis of conditions in the basin prior to large-scale ground-water development indicates that net recharge equaled 9.23 cubic feet per second and occurred as subsurface flow to the eastern part of the basin and infiltration of rain, direct runoff, and minor streamflows. Net predevelopment discharge equaled 9.23 cubic feet per second and occurred as aquifer discharge to the San Benito River. The 9.23 cubic feet per second of predevelopment recharge is considered to be perennial recharge to the basin.
Large-scale ground-water development occurred in the area during the period 1945-68 and caused water levels to decline throughout most of the basin. Progressive depletion of aquifer storage during this period changed the San Benito River from a gaining (perennial) stream to a losing stream along most of its reach in the basin area. Net discharge from the basin during the period 1945-68 averaged 18.10 cubic feet per second. Of this amount 17.82 cubic feet per second occurred as pumpage from wells, and
0.28 cubic foot per second occurred as basin discharge to the San Benito River. Net recharge to the basin during the same period averaged 13.57 cubic feet per second. Of this amount 4.34 cubic feet per second occurred as infiltration from the San Benito River and 9.23 cubic feet per second occurred as perennial recharge.
Use of the calibrated mathematical model to simulate quantities of imported water entering the basin from the San Benito River indicates that water levels in San Juan Valley will stabilize or recover when additional recharge equals or exceeds 3,000 acre-feet per year.

The model was calibrated by using observed rainfall and runoff data from 19 storms in six basins having various degrees of urbanization. The calibrated models were used with a 57- year rainfall record to simulate 57-year records of annual peak discharges in 14 basins. The flood-frequency characteristics were defined by fitting the simulated 57-year records to log-Pearson Type III distributions.
\nRegional peak-discharge equations, which can be used to determine the maximum rates of discharge that could be expected to be equaled or exceeded on the average of once in 1.25, 2, 5, 10, 25, and 100 years, were derived from multiple-regression analyses. The relationships among flood frequency, drainage area, and a coefficient of impervious area are given in a nomograph.
\nThe analyses indicate that in a fully-developed residential area, the flood peaks will be 1.2 to 1.4 times those from an undeveloped area; and the annual direct runoff will be about double that from an undeveloped area. Data were not sufficient to determine the increase in runoff from a highly industrialized area where the effective imperviousness approaches 100 percent.
