The Lake Minnequa area, located immediately south of the Arkansas River near Pueblo, Colo., is mantled with as much as 46 feet (14 meters) of alluvium covering bedrock of Pierre Shale and Niobrara Formation. Surface water enters the area by the Minnequa Canal and the St. Charles Flood Ditch. The...
Water levels in artesian and nonartesian aquifers of Florida, 1973-74
Henry G. Healy
1976, Water-Resources Investigations Report 76-101
Based on measurements of water level in 675 wells selected from a network of about 1,300 observation wells, ground-water levels during May 1973 - May 1974 declined from 2 to 4 feet in the Floridan aquifer through most of north and central peninsular Florida. Hydrographs of 55 wells show the...
Mapping and measuring land-cover characteristics of New River Basin, Tennessee, using Landsat digital tapes
E. F. Hollyday, S.P. Sauer
1976, Water-Resources Investigations Report 76-106
Land-cover information is needed to select subbasins within the New River basin, Tennessee, for the study of hydrologic processes and also is needed to transfer study results to other sites affected by coal mining. It was believed that data recorded by the first Earth Resources Technology Satellite (Landsat-1) could be...
Estimating runoff volumes and flood hydrographs in the Colorado River Basin, southern Utah
James H. Eychaner
1976, Water-Resources Investigations Report 76-102
Hydrographs of 364 floods from 18 continuous-record gaging sites in the Colorado River basin in southern Utah were used to define a single relation of flood volume to peak discharge; the standard error of estimate of that relation . is 82 percent. Using the same data, a mean dimensionless hydrograph...
Backflushing Filters for Field Processing of Water Samples Prior to Trace-Element Analyses
V. C. Kennedy, E. A. Jenne, J.M. Burchard
1976, Water-Resources Investigations Report 76-126
A portable unit is described for filtering water samples at field sites in such a manner that the filtrate is suitable for analysis not only of major constituents but also of trace elments at the mocrogram-per-liter level. A battery-operated peristaltic pump forces the water sample through medical-grade silicone tubing into...
Mathematical model of the West Bolsa Ground-water Basin, San Benito County, California
Robert E. Faye
1976, Water-Resources Investigations Report 76-71
Simulation of the West Bolsa ground-water basin hydrology in California had provided values of basin recharge and discharge and nodally distributed values of transmissivity and storage coefficient. Average net recharge from April 1945 to March 1969 was 6.2 cubic feet per second and occurred as subsurace recharge and infiltration of...
Sediment discharge from highway cut-slopes in the Lake Tahoe Basin, California, 1972-74
Carl G. Kroll
1976, Water-Resources Investigations Report 76-19
Streamflow and fluvial-sediment discharge data were collected at selected streams and highway gutters in the Lake Tahoe basin to determine the extent of erosion from highway cuts and to attempt to evaluate the effects of various land-treatment practices to reduce erosion.Estimate of long-term annual total-sediment discharge from six streams into...
Technique for estimating magnitude and frequency of floods in Kentucky
Curtis H. Hannum
1976, Water-Resources Investigations Report 76-62
Flood magnitude and frequency relations applicable to unregulated stream in Kentucky are based on flood data at 117 gaging stations in Kentucky and 14 in adjacent states having 10 or more years of record. Equations that related flood magnitude and frequency to contributing drainage area in 16 geographic areas may...
