Techniques for estimating the magnitude and frequency of floods in the Dallas - Fort Worth metropolitan area, Texas
Larry F. Land, Elmer E. Schroeder, B.B. Hampton
1982, Water-Resources Investigations Report 82-18
Equations for predicting the magnitude and frequency of floods in the Dallas-Fort Worth metropolitan area were developed from recorded data from streams with drainage areas ranging in size from 1.25 to 66.4 square miles. The U. S. Geological Survey urban rainfall-runoff model was used to generate long-term flood-discharge record for...

Digital classification of Landsat data for vegetation and land-cover mapping in the Blackfoot River watershed, southeastern Idaho
L. R. Pettinger
1982, Professional Paper 1219
This paper documents the procedures, results, and final products of a digital analysis of Landsat data used to produce a vegetation and landcover map of the Blackfoot River watershed in southeastern Idaho. Resource classes were identified at two levels of detail: generalized Level I classes (for example, forest land and...

Late Cenozoic stratigraphy and structure of the western margin of the central San Joaquin Valley, California
William R. Lettis
1982, Open-File Report 82-526
Late Cenozoic Stratigraphy Late Cenozoic deposits in the west-central San Joaquin Valley and adjacent foothills of the Diablo Range consist mainly of unconsolidated, poorly-sorted to well-sorted gravel, sand, silt and clay derived primarily from the Diablo Range and secondarily from the Sierra Nevada. Sedimentary structures, such as channeled contacts, laminated...

Effects of flooding upon woody vegetation along parts of the Potomac River flood plain
T.M. Yanosky
1982, Professional Paper 1206
A two-part study along the Potomac River flood plain near Washington, D.C., was undertaken to investigate the effects of flooding upon woody vegetation. Floods abrade bark, damage branches and canopies, and often uproot trees. The first study was of vegetation in five monumented flood-plain plots which differed in the frequency...
Some silicified strophomenacean brachiopods from the Ordovician of Kentucky, with comments on the genus Pionomena
J.K. Pope
1982, Professional Paper 1066-L
Eight species of silicified strophomenid brachiopods from Ordovician rocks of Kentucky are described in this report. Seven species are strophomenaceans, including six from the Middle Ordovician and one, Leptaena kentuckiana n. sp., from the Upper Ordovician. Pionomena recens Neuman from the Middle Ordovician is referred to the Davidsoniacea. Three of...
Water levels in Nassau County Sewer Districts 2 and 3, Long Island, New York, 1978-79
H. F. Ku, D. L. Simmons
1982, Water-Resources Investigations Report 82-4017
Prior to development on Long Island, about 95 percent of total streamflow originated as groundwater seepage from the upper glacial aquifer; the remaining 5 percent consisted of direct storm runoff. Thus, the streams on Long Island function as groundwater drains. Their flow in dry weather is directly controlled by groundwater...

Perennial-streamflow characteristics related to channel geometry and sediment in Missouri River basin
W. R. Osterkamp, E. R. Hedman
1982, Professional Paper 1242
Geometry, channel-sediment, and discharge data were collected and compiled from 252 streamflow-gaging stations in the Missouri River basin. The sites represent the complete ranges of hydrologic and geologic conditions found in the basin. The data were analyzed by computer to yield equations relating various discharge characteristics to variables of channel...

Ground-water monitoring at Santa Barbara, California; Phase 2-effects of pumping on water levels and water quality in the Santa Barbara ground-water basins
Peter Martin
1982, Open-File Report 82-366
From July 1978 to January 1980, water levels declined more than 100 feet in the southern part of the Santa Barbara ground-water basin. The water-level declines are the result of increases in municipal pumping since July 1978. The increase in municipal pumping was part of a basin-testing program to determine...
The brachiopod genera Hebertella, Dalmanella, and Heterorthina from the Ordovician of Kentucky
L.G. Walker
1982, Professional Paper 1066-M
The orthid brachiopod genera Hebertella, Dalmanella, and Heterorthina are abundant in Middle and Upper Ordovician strata in Kentucky. 'Nine species are described: Hebertella frankfortensis Foerste; H. parksensis Foerste; H. occidentalis (Hall); Dalmanella bassleri Foerste; D. fertilis (Ulrich); D. meeki (Miller); D. multisecta (Meek); D. sulcata Cooper; and Heterorthina macfarlani Neuman....
A digital-computer model of the Big Sioux aquifer in Minnehaha County, South Dakota
N.C. Koch
1982, Water-Resources Investigations Report 82-4064
A finite-difference digital model was used to simulate steady-state conditions of the Big Sioux aquifer in Minnehaha County. Average water levels and average base flow discharge (4.9 cu ft/s) of the Big Sioux River were based on data from 1970 through 1979. The computer model was calibrated for transient conditions...

Estimating peak flow characteristics at ungaged sites by ridge regression
Gary D. Tasker
1982, Open-File Report 82-333
A regression simulation model, is combined with a multisite streamflow generator to simulate a regional regression of 50-year peak discharge against a set of basin characteristics. Monte Carlo experiments are used to compare the unbiased ordinary lease squares parameter estimator with Hoerl and Kennard's (1970a) ridge estimator in which the...
