Erosion \r\non the Zuni Indian Reservation includes channel erosion (arroyo incision \r\nand channel widening) and hillslope (sheetwash) erosion. The U.S. Geological \r\nSurvey conducted a 3-year (1992-95) study on channel erosion and hillslope \r\nerosion in the portion of the Rio Nutria watershed that drains entirely within \r\nthe Zuni Indian Reservation. Results of the study can be used by the Zuni Tribe \r\nto develop a plan for watershed rehabilitation. \r\n\r\n     Channel changes, gully growth, headcuts, and changes in dirt roads \r\nover time were examined to characterize and evaluate channel erosion in the \r\nRio Nutria watershed. Channel cross-sectional changes included width, depth, \r\nwidth-to-depth ratio, area, and geometry. Relative rates of gully growth, \r\nheadcuts, and changes in dirt roads over time were examined using aerial \r\nphotographs. Results of resurveys conducted between 1992 and 1994 of 85 \r\nchannel cross sections indicated aggradation of 72 percent of cross sections \r\nin three subbasins of the Rio Nutria watershed. Forty-eight percent of \r\nresurveyed cross sections showed an increase in cross-sectional area and  \r\nerosion; nine of these are in tributaries. Some channels (43 percent) \r\naggraded and increased in cross-sectional area. This increase in cross- \r\nsectional area is due mostly to widening. Channel widening is a more pervasive \r\nform of erosion than channel scour on the Zuni Indian Reservation. The tops \r\nof channels widened in 67 percent and the bottoms of channels widened in 44 \r\npercent of resurveyed cross sections. Narrow, deep triangular channels are \r\nmore erosive than rectangular cross sections.\r\n\r\n     Five land-cover types--three sites on mixed-grass pasture, two sites on \r\nsites on unchained pi?on and juniper, one site on sagebrush, one site on\r\nponderosa pine, and two sites on chained pi?on and juniper--were each \r\ninstrumented with sediment traps between 1992 and 1994 to measure hillslope \r\nerosion. Highest sediment yields were measured at chained areas and mixed- \r\ngrass pasture. Annual yields from sites that were operated for more than a  \r\nyear were 11.7, 6.0, and 6.5 metric tons per square kilometer per year at a  \r\npi?on and juniper site, mixed-grass pasture site, and sagebrush site, \r\nrespectively.","language":"ENGLISH","publisher":"U.S. Dept. of the Interior, U.S. Geological Survey :\r\nDenver, CO : Branch of Information Services [distributor],","doi":"10.3133/wri974281","usgsCitation":"Gellis, A., 1998, Characterization and evaluation of channel and hillslope erosion on the Zuni Indian Reservation, New Mexico, 1992-95: U.S. Geological Survey Water-Resources Investigations Report 97-4281, iv, 51 p. :ill.

The hydrology of these areas differs in that Ocala has many karst depressions but virtually no surface-water features, and Tampa and Virginia Beach have numerous surface-water features, including small lakes, streams, and swamps. Samples were collected in early 1995 from 15 wells in Ocala (8 in the surficial aquifer and 7 in the Upper Floridan aquifer), 17 wells in Tampa (8 in the surficial aquifer and 9 in the Upper Floridan aquifer), and in the summer of 1995 from 15 wells in Virginia Beach (all in the surficial aquifer).</span></p><p>In the surficial aquifer in Ocala, the major ion water type was calcium bicarbonate in five samples and mixed (no dominant ions) in three samples, with dissolved-solids concentrations ranging from 78 to 463 milligrams per liter. In Tampa, the water type was calcium bicarbonate in one sample and mixed in seven samples, with dissolved-solids concentrations ranging from 38 to 397 milligrams per liter. In Virginia Beach, water types were primarily calcium and sodium bicarbonate water, with dissolved-solids concentrations ranging from 89 to 740 milligrams per liter. The water types and dissolved-solids concentrations reflect the presence of carbonates in the surficial aquifer materials in the Ocala and Virginia Beach areas. The major ion water type was calcium bicarbonate for all 16 samples from the upper Floridan aquifer in both Florida cities. Dissolved-solids concentrations ranged from 210 to 551 milligrams per liter in Ocala, with a median of 287 milligrams per liter, and from 187 to 362 milligrams per liter in Tampa, with a median of 244 milligrams per liter.</p><p>Concentrations of nitrate nitrogen were highest in the surficial aquifer in Ocala, and one sample ex-ceeded 10 milligrams per liter, the U.S. Environmental Protection Agency maximum contaminant level for drinking water. Median nitrate concentrations were 1.2 milligrams per liter in Ocala and only 0.06 and 0.05 milligram per liter in Tampa and Virginia Beach, respectively. In Florida, some background water-quality data were available for comparison. The median nitrate concentration in Ocala was much higher than the median nitrate concentration of 0.05 milligram per liter in the background data. Median nitrate concentrations were 0.33 and 0.05 milligram per liter in samples from the Upper Floridan aquifer in Ocala and Tampa, respectively, and 0.05 milligram per liter in background samples.</p><p>Of the 47 pesticides and 60 volatile organic compounds analyzed, only five pesticides and five volatile organic compounds were detected. The most commonly detected pesticide was prometon, a broad-scale herbicide, detected in samples from eight wells in Ocala (at concentrations ranging from 0.009 to 1.8 micrograms per liter), three wells in Virginia Beach (at concentrations ranging from 0.19 to 10 micrograms per liter), and from one well in Tampa (0.01 microgram per liter). The most commonly detected volatile organic compound was chloroform, which was d etected four times at concentrations ranging from 0.3 to 2.2 micrograms per liter in Ocala and Tampa. Seven volatile organic compounds were detected in one sample in Virginia Beach; most were compounds associated with petroleum and coal tar.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri974234","usgsCitation":"Berndt, M.P., Galeone, D., Spruill, T., and Crandall, C.A., 1998, Ground-water quality in three urban areas in the Coastal Plain of the southeastern United States, 1995: U.S. Geological Survey Water-Resources Investigations Report 97-4234, iii, 25 p., https://doi.org/10.3133/wri974234.","productDescription":"iii, 25 p.","costCenters":[],"links":[{"id":125075,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/wri_97_4234.jpg"},{"id":1906,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/wri974234","linkFileType":{"id":5,"text":"html"}},{"id":465855,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_48839.htm","text":"Ocala, Florida","linkFileType":{"id":5,"text":"html"}},{"id":465856,"rank":4,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_48840.htm","text":"Tampa, Florida","linkFileType":{"id":5,"text":"html"}},{"id":465857,"rank":5,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_48841.htm","text":"Virginia Beach, Virginia","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a8ee4b07f02db6548fb","contributors":{"authors":[{"text":"Berndt, M.

The Lake Valley ACEC is along the southeastern margin of the Black Range of western Sierra County, New Mexico. The Black Range contains eleven mining districts from which silver, lead, zinc, manganese, copper, gold, and tin have been recovered. As part of the study, an area of over 75 square mi (195 square km) in the area of the Lake Valley ACEC was mapped to understand ore controls and to assess mineral-resource potential. Lake Valley mining district is in Mississippian Lake Valley Formation carbonate rocks, but much of the surrounding terrane consists of volcanic rocks on the southeastern edge of the Emory cauldron which formed about 34.9 Ma. Volcanic rocks are part of the Mogollon-Datil volcanic province which include flows, breccias, ash-flow tuffs, and intrusive rhyolites. The Lake Valley mining district is located about 20 mi (32 km) south of the Late Cretaceous Laramide copper-gold porphyry intrusion at Hillsboro. It is also located at the western boundary of the Rio Grande rift basin.The Lake Valey fault is the major structural feature of the study area. Geological and geophysical data suggest the fault is composed of two segments: a southern, northwest-striking segment that may have a pre-Tertiary history and a northerly-striking segment that is part of the Emory cauldron ring fracture. The mining district is bounded by the southern, northwest-striking segment of the fault which may have up to 800 ft (240m) of normal offset. Deposit types identified in the Black Range, and for which we assess mineral potential, are Laramide porphyry, Laramide skarns, Laramide veins, gold placer, carbonate-hosted, volcanic-epithermal, and rhyolite tin; no Rio Grande Rift baritefluorite-galena deposits are known, but they are included in the assessment. The most likely deposits to be discovered in the Lake Valley district are carbonate-hosted silver-manganese deposits. These deposits could be deposited by hydrothermal fluids or be related to intrusion of Oligocene rhyolite or Laramide porphyry. An aeromagnetic high south of the district probably reflects a small felsic intrusion of unknown age. We assess the Lake Valley ACEC as having low to moderate potential for undiscovered carbonate-hosted deposits associated with volcanic rocks or Laramide porphyry plutons, and low potential for gold placer and rhyolite tin deposits.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr98347","usgsCitation":"Nutt, C., O’Neill, J., McLemore, V., Lindsey, D.A., Ratte, J., Hedlund, D.C., Klein, D.P., and Kleinkopf, M.D., 1998, Geology and mineral resources of the Lake Valley area, Sierra County, New Mexico: U.S. Geological Survey Open-File Report 98-347, Report: 70 p.; 1 Plate: 34.99 x 42.51 inches, https://doi.org/10.3133/ofr98347.","productDescription":"Report: 70 p.; 1 Plate: 34.99 x 42.51 inches","costCenters":[],"links":[{"id":153574,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1998/0347/report-thumb.jpg"},{"id":399846,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1998/0347/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":399847,"rank":3,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1998/0347/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}}],"scale":"24000","country":"United States","state":"New Mexico","county":"Sierra County","otherGeospatial":"Lake Valley area","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -107.6381,\n              32.875\n            ],\n            [\n              -107.5,\n              32.875\n            ],\n            [\n              -107.5,\n              32.6928\n            ],\n            [\n              -107.6381,\n              32.6928\n            ],\n            [\n              -107.6381,\n              32.875\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b32e4b07f02db6b471c","contributors":{"authors":[{"text":"Nutt, C.J.","contributorId":52577,"corporation":false,"usgs":true,"family":"Nutt","given":"C.J.","email":"","affiliations":[],"preferred":false,"id":185866,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"O’Neill, J.M.","contributorId":85562,"corporation":false,"usgs":true,"family":"O’Neill","given":"J.M.","email":"","affiliations":[],"preferred":false,"id":185867,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McLemore, V.

Modern horizontal long period seismometers with their long natural periods are incredibly sensitive to tilt. They can sense tilts smaller than <span>10</span><sup>-11</sup> radians. To most readers, this is just a very very small number, so we will begin with an example, which should help to illustrate just how small 10<sup>-11</sup> radians is.</p><p>Suppose we have an absolutely rigid rod which is approximately 4170 kilometers long; this just happens to be the Rand McNally map scaled crow flight distance between Los Angeles and Boston. Tilting this rod <span>10</span><sup>-11</sup> radians corresponds to raising one end of the rod 0.0000417 meters. Alas, this is just another very very small number! However, this corresponds to slipping a little less than one third a sheet of ordinary copying paper under one end of this perfectly rigid rod. To clarify, we mean, take a sheet of paper just like the paper this report is printed on and split it a little less than one third in the thickness direction, then put it under the end of the 4170 kilometer long rod! This will tilt the rod <span>10</span><sup>-11</sup> radians.</p><p>Real world seismometers are nowhere near the length of this rod. A KS-54000 is about two meters long. Tilting a rod only two meters long 10~n radians corresponds to moving one end of this rod a mere 0.00000000002 meters or 0.02 millimicrons. As one of the authors old math teachers used to say, \"That's PDS\" (PDS = Pretty Damn Small). Unfortunately, the long period seismologist does not have the luxury of ignoring PDS numbers when it suits him as the mathematician frequently does. He must live in the real world in which tilts this small create severe contamination of long period seismic data.</p><p>At periods longer than 20 seconds, tilt noise contaminates the long period data from all instruments installed on or near the earth's surface. Many years of experimentation revealed that installing the sensors at depth in deep mines drastically reduced the level of tilt noise in long period data. However, low levels of tilt noise persisted even at great depth; this noise was caused by air convection in the vault in which the sensors were installed. Over the years, methods were developed to control the air motion with mechanical barriers (boxes) around the sensors and by stratifying (creating a situation in which the air temperature increases with height) the air in the vault near the seismometer. These methods decreased tilt noise in deep mines to very low levels. However, deep mines, that are economically and environmentally suitable and accessible to seismology, are not plentiful and are not evenly distributed over the earth's surface. Therefore, the borehole deployable Teledyne Geotech KS-36000 and later the KS-54000 sensor systems were developed to fulfill the need for instruments that could be installed at depth wherever high quality long period data was desired. Early in the development program, it became evident to the Teledyne Geotech personnel that air convection within the borehole was going to be a significant problem in KS deployments. Experimental and theoretical investigations conducted by Teledyne Geotech (see Douze and Sherwin, 1975, and Sherwin and Cook, 1976) produced a list of recommended installation procedures for reducing the effects of air convection. These procedures consisted of wrapping the sensor in a relatively thin layer of foam insulation, filling the free space volume in the vicinity of the centralizer-bail assembly with foam insulation, and the installation of styrofoam hole plugs immediately above the cable strain relief assembly at the top of the sensor package and at the top of the borehole. This technology has performed quite satisfactorily for over 20 years but evidence of tilt noise in the system output has persisted throughout the KS deployment program (the evidence was that the horizontal components were usually noisier than the vertical components) even in deep boreholes. Some deep borehole sites have been plagued by quite high levels of horizontal noise. Therefore, there has been a definite need for a new technique for controlling low level tilt noise in deep boreholes and the use of sand has been under consideration for several years.</p><p>Figure 1 contains conceptual illustrations of both the conventional holelock installed KS sensor system and the same sensor installed in sand. This figure demonstrates the major differences between the two installation methods. The curved arrows in the borehole on the left in the figure denote possible air convection cells which are believed to be the source of tilt noise in some of the conventional installations. This air motion is eliminated in a sand installation by filling most of the free air volume surrounding the seismometer with sand as shown in the right hand portion of the figure. The sand actually performs two functions; it prevents air motion and provides a remarkably ridgid clamping of the seismometer in the borehole. </p><p>This report presents the results of quantitative experimental investigations into the effectiveness of controlling low level air convection in seismic borehole installations with sand. The main body of the experimental effort consisted of installing two KS-540001 sensor systems in closely spaced shallow boreholes, allowing the sensors to reach equilibrium operation, and then pouring sand into both boreholes to observe any changes caused by pouring sand into the holes. The hypothesis of the experiment was that the sand would fill up the entire free air volume between the sensor package and the borehole walls thereby preventing movement of the air in the vicinity of the sensor package. The validity of this hypothesis had been qualitatively proven by earlier experiments at ASL and by the sand installations at the IRIS/ASL stations ANMO in 1995 and COLA in 1996. This experiment documents the degree of improved noise levels to be expected if KS instruments are installed in sand instead of in the conventional manner.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr98362","issn":"0094-9140","usgsCitation":"Holcomb, L.G., Sandoval, L., and Hutt, B., 1998, Experimental investigations regarding the use of sand as an inhibitor of air convection in deep seismic boreholes: U.S. Geological Survey Open-File Report 98-362, iii, 53 p., https://doi.org/10.3133/ofr98362.","productDescription":"iii, 53 p.","costCenters":[{"id":122,"text":"Albuquerque Seismological Laboratory","active":false,"usgs":true}],"links":[{"id":156751,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1998/0362/coverthb.jpg"},{"id":52658,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1998/0362/ofr98-362.pdf","text":"Report","size":"3.57 MB","linkFileType":{"id":1,"text":"pdf"},"description":"OFR 1998-0362"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a07e4b07f02db5f93e1","contributors":{"authors":[{"text":"Holcomb, L.

Long-term method detection levels (LT-MDLs) for MTBE, TAME, DIPE, and ETBE ranged from 15 to 83 nanograms per liter (0.015 to 0.083 microgram per liter). Nanogram-per-liter-concentration detections are reported if all of the identification criteria are met, whereas previous methods censored detections at a pre-determined method reporting level. The reporting level for this method is defined as two times the LT-MDL, does not censor detections at less than this concentration, and is referred to as the nondetection value (NDV). Bias and variability data from multiple analyses, analysts, and instruments over a 60-day period show the oxygenate recoveries ranging from 100 to 109 percent, with 6 to 8 percent relative standard deviation. MTBE, TAME, DIPE, and ETBE were not detected in the analysis of 225 laboratory reagent blanks from January to December 1997. A preservation study in ground water and surface water indicates that all the oxygenates are stable at pH 2 for up to 216 days, with recoveries ranging from 94 to 115 percent on day 216, and relative standard deviations ranging from 5 to 9 percent for the duration of the study.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/fs08698","usgsCitation":"Rose, D.L., Connor, B.F., Abney, S.R., and Raese, J.W., 1998, Laboratory method for analysis of small concentrations of methyl tert-butyl rther and other ether gasoline oxygenates in water: U.S. Geological Survey Fact Sheet 086-98, 6 p., https://doi.org/10.3133/fs08698.","productDescription":"6 p.","costCenters":[{"id":452,"text":"National Water Quality Laboratory","active":true,"usgs":true},{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"links":[{"id":124448,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/fs/1998/0086/report-thumb.jpg"},{"id":11565,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://nwql.usgs.gov/Public/FS-086-98.shtml","linkFileType":{"id":5,"text":"html"}},{"id":32104,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/fs/1998/0086/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b28e4b07f02db6b1483","contributors":{"authors":[{"text":"Rose, Donna L. 0000-0003-1216-9914 dlrose@usgs.gov","orcid":"https://orcid.org/0000-0003-1216-9914","contributorId":4546,"corporation":false,"usgs":true,"family":"Rose","given":"Donna","email":"dlrose@usgs.gov","middleInitial":"L.","affiliations":[{"id":5046,"text":"Branch of Analytical Serv (NWQL)","active":true,"usgs":true}],"preferred":true,"id":151235,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Connor, Brooke F. bfconnor@usgs.gov","contributorId":3172,"corporation":false,"usgs":true,"family":"Connor","given":"Brooke","email":"bfconnor@usgs.gov","middleInitial":"F.","affiliations":[],"preferred":true,"id":151234,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Abney, Sonja R.","contributorId":62992,"corporation":false,"usgs":true,"family":"Abney","given":"Sonja","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":151236,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Raese, Jon W. jwraese@usgs.gov","contributorId":183,"corporation":false,"usgs":true,"family":"Raese","given":"Jon","email":"jwraese@usgs.gov","middleInitial":"W.","affiliations":[],"preferred":true,"id":151233,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

In general terms, displacement of the seafloor during the earthquake rupture is modeled using the elastic dislocation theory for which the displacement field is dependent on the slip distribution, fault geometry, and the elastic response and properties of the medium. Specifically, nonlinear long-wave theory governs the propagation and run-up of tsunamis. A parametric study is devised to examine the relative importance of individual earthquake source parameters on local tsunamis, because the physics that describes tsunamis from generation through run-up is complex. Analysis of the source parameters of various tsunamigenic earthquakes have indicated that the details of the earthquake source, namely, nonuniform distribution of slip along the fault plane, have a significant effect on the local tsunami run-up. Numerical methods have been developed to address the realistic bathymetric and shoreline conditions. The accuracy of determining the run-up on shore is directly dependent on the source parameters of the earthquake, which provide the initial conditions used for the hydrodynamic models.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Advances in geophysics","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"Academic Press","publisherLocation":"New York","doi":"10.1016/S0065-2687(08)60276-9","usgsCitation":"Geist, E.L., 1998, Local tsunamis and earthquake source parameters, chap. <i>of</i> Advances in geophysics, v. 39, p. 117-209, https://doi.org/10.1016/S0065-2687(08)60276-9.","productDescription":"93 p.","startPage":"117","endPage":"209","numberOfPages":"93","costCenters":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":281151,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"39","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd64dee4b0b290850ffb7f","contributors":{"editors":[{"text":"Dmowska, Renata","contributorId":113463,"corporation":false,"usgs":true,"family":"Dmowska","given":"Renata","email":"","affiliations":[],"preferred":false,"id":509703,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Saltzman, Barry","contributorId":112306,"corporation":false,"usgs":true,"family":"Saltzman","given":"Barry","email":"","affiliations":[],"preferred":false,"id":509702,"contributorType":{"id":2,"text":"Editors"},"rank":2}],"authors":[{"text":"Geist, Eric L. 0000-0003-0611-1150 egeist@usgs.gov","orcid":"https://orcid.org/0000-0003-0611-1150","contributorId":1956,"corporation":false,"usgs":true,"family":"Geist","given":"Eric","email":"egeist@usgs.gov","middleInitial":"L.","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true},{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"preferred":true,"id":488587,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
