Regional decline of aquifer head due to ground-water withdrawal in the Houston area has caused extensive land-surface subsidence. The NASA-Johnson Space Center (NASA-JSC) in southeastern Harris County, Texas, was about 13 to 19 feet above mean sea level in 1974 and sinking at a rate of more than 0.2 foot per year. NASA-JSC officials, concerned about the hurricane flooding hazard...

Detailed rainfall-runoff computations, including hydrographs and mass curves, are presented for nine storm periods during the 1975 water year in drainage basins in the Houston, Texas metropolitan area. The information will be useful in determining the extent to which progressive urbanization will affect the yield and mode of occurrence of storm runoff. (Woodard-USGS)

Drainage area, slope, and mean annual precipitation were the only factors that were statistically significant at the 95-percent confidence level when the characteristics of the drainage basins were used as independent variables in a multiple-regression flood-frequency analysis of natural, unregulated streams in Texas. The State was divided into six regions on the basis of the...

Most of the data presented in this report were collected by the U.S. Geological Survey as part of a study of the geohydrology of the Vamoosa aquifer, in east-central Oklahoma, in cooperation with the Oklahoma Geological Survey. Some of the data listed in the tables were collected by Bingham and Moore (1975) and Bingham and Bergman (in press). Acknowledgment is extended to city officials...

Water resources data for the 1976 water year for Georgia consists of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs. This report contains discharge records for 99 gaging stations; stage for 9 gaging stations, stage and contents for 16 lakes and reservoirs; water quality for 20 continuous stations and 108 periodic stations. Also...

A method is presented for estimating the magnitude and frequency of floods for urban streams in metropolitan Atlanta. The method is based on adjustments to the natural stream flood-frequency and rainfall-frequency characteristics of the local area as defined by urban flood studies in other areas. The effects of urbanization on flood-peak runoff are estimated from the percentage of...

This report contains the rainfall, runoff, and storage data collected during the 1975 water year for the 21.6-square-mile area above the stream-gaging station North Creek near Jacksboro, Texas. The weighted-mean rainfall in the study area during the water year was 39.01 inches, which is greater than the 18-year average of 30.21 inches for the period 1958-75. Monthly rainfall totals...

This report contains rainfall, runoff, and storage data collected during the 1975 water year for a 75.5 sq mi area above the stream-gaging station Little Elm Creek near Aubrey, Texas. Floodflows from 35.7 sq mi of the area are regulated by 16 floodwater-retarding structures constructed by the Soil Conservation Service. Six storm periods were selected for detailed computations and...

Flood information for the Big Creek basin in Linn County, Iowa, should be of use to those concerned with the design of bridges and other structures on the flood plains of the streams. Water-surface profiles for the flood of May 1974 are given for Big Creek and its major tributaries, East Big, Crabapple, Elbow, and Abbe Creeks. The May 1974 flood was at least a 50-year flood on East Big...
