Runoff Studies on Small Drainage Areas. Technique for Estimating Magnitude and Frequency of Floods in West Virginia

摘要

A technique is presented for estimating the magnitude and frequency of floods on unregulated, virtually natural streams in West Virginia. Multiple-regression techniques were used to develop relations between dependent variables, flood peaks, and independent variable, drainage areas. Data collected at 170 stream-gaging sites were used in the analyses. Peak discharges can be estimated for drainage areas from about 0.3 square mile up to 2000 square miles. Graphs are provided to estimate the flood peak.
