Geologic framework and hydrogeologic properties of the Seco Creek Watershed, Texas Geologic framework and hydrogeologic properties of the Seco Creek Watershed, Texas
In 1991, the U.S. Geological Survey (USGS), in cooperation with the U.S. Department of Agriculture (USDA) and the Texas State Soil and Water Conservation Board, began a study to evaluate the effects of agricultural best-management practices on surface- and ground-water quantity and quality in the Seco Creek watershed. The USGS study is part of a larger study known as the Seco Creek Water...

Site-specific estimation of peak-streamflow frequency using generalized least-squares regression for natural basins in Texas Site-specific estimation of peak-streamflow frequency using generalized least-squares regression for natural basins in Texas
The U.S. Geological Survey, in cooperation with the Texas Department of Transportation, has developed a computer program to estimate peak-streamflow frequency for ungaged sites in natural basins in Texas. Peak-streamflow frequency refers to the peak streamflows for recurrence intervals of 2, 5, 10, 25, 50, and 100 years. Peak-streamflow frequency estimates are needed by planners...

Precipitation, atmospheric deposition, streamflow, and water-quality data from selected sites in the city of Charlotte and Mecklenburg County, North Carolina, 1997–98 Precipitation, atmospheric deposition, streamflow, and water-quality data from selected sites in the city of Charlotte and Mecklenburg County, North Carolina, 1997–98
Precipitation data were collected at 46 precipitation sites and 3 atmospheric deposition sites, and hydrologic data were collected at 6 stream sites in the vicinity of Charlotte and Mecklenburg County, North Carolina, from July 1997 through September 1998. Data were collected to identify the type, concentration, and amount of nonpoint-source stormwater runoff in the study area. The data...

Effects on ground-water levels in the Missouri River alluvial aquifer caused by changes in Missouri River stage, Fremont and Monona Counties, Iowa Effects on ground-water levels in the Missouri River alluvial aquifer caused by changes in Missouri River stage, Fremont and Monona Counties, Iowa
An analysis of available hydrologic data was conducted to evaluate the effects on groundwater levels in the Missouri River alluvial aquifer caused by changes in Missouri River stage at selected sites in Fremont and Monona Counties in western Iowa. Daily mean ground-water levels and river stage measured during November 1995- September 1996, simulated daily mean river stage for November...

Quality of ground water in Webb County, Texas, 1997-98 Quality of ground water in Webb County, Texas, 1997-98
Rapid development and population growth are occurring in Webb County in south Texas (fig. 1). Water managers need information on the ground-water resources of the area to address the increased demand for water caused by the development. To help meet this need, the U.S. Geological Survey (USGS), in cooperation with the City of Laredo, began a study in 1997 to assess the ground-water...

Gravel sediment routing from widespread, low-intensity landscape disturbance, Current River basin, Missouri Gravel sediment routing from widespread, low-intensity landscape disturbance, Current River basin, Missouri
During the last 160 years, land-use changes in the Ozarks have had the potential to cause widespread, low-intensity delivery of excess amounts of gravel-sized sediment to stream channels. Previous studies have indicated that this excess gravel bedload is moving in wave-like forms through Ozarks drainage basins. The longitudinal, areal distribution of gravel bars along 160 km of the...

Tolerance of an albino fish to ultraviolet-B radiation Tolerance of an albino fish to ultraviolet-B radiation
We exposed albino and pigmented medakaOryzias latipes to simulated solar ultraviolet-B (UVB) radiation to determine if albino medaka were less tolerant of UVB radiation than medaka pigmented with melanin. There was no difference in the number of albino and pigmented medaka that died during the exposure period. Spectrophotometric analyses of the outer dorsal skin layers from albino and...
