FLOOD PEAK ESTIMATES FROM SMALL RURAL WATERSHEDS

The design of highway drainage structures depends on accurate estimates of flood hydrographs of streams that cross highways. This article describes the special characteristics of small rural watersheds and the Federal Highway Administration's extensive involvement in a program of small-stream gaging, data analysis, and methods development for such estimates. The results of the five major complete studies are reported here. Available data on rainfall and streamflow from small rural watersheds are insufficient, and the geographical distribution of streamflow data is extremely poor. These conditions greatly hamper progress toward development of accurate general methods for estimation of flood peaks from small rural watersheds for nationwide use. However, better methods for estimation of flood peaks can be developed for local use on the marginal local data by researchers who know the area well.
