H. R. Anderson
1976, Water-Resources Investigations Report 75-41
Ground water in the San Juan, Puerto Rico, area has played a declining role in water supply since the completion of the Lofza reservoir project in the early 1950's. Ground-water potential is limited because of the small size of the aquifers and susceptibility to seawater intrusion. Of the 30 million...

Technical manual for estimating low-flow frequency characteristics of streams in the Susquehanna River basin
Jeffrey T. Armbruster
1976, Water-Resources Investigations Report 76-51
This report presents procedures for estimating low-flow frequency characteristics for streams in the Susquehanna River basin. The techniques can be used at ungaged sites as well as sites where insufficient data are available to make a reliable estimate. Streams have been divided intp two types--major and minor. Major streams are...
Effects of urbanization on flood characteristics in Nashville-Davidson County, Tennessee
Herman C. Wibben
1976, Water-Resources Investigations Report 76-121
Streamflow data from 14 basins in Davidson County, Tenn., were extended in time by use of a digital model of the hydrologic system. The basins ranged in size from 1.58 to 64.0 square miles and ranged in extent of manmade impervious cover from 3 to 37 percent. The flood-frequency characteristics...
