Within this region, annual maximum floods, on watersheds less than 1000 square miles, are usually the result of intense rainfall over a limited area. The investigation reveals that peak rates of runoff from ungagged watersheds can be estimated from parameters of watershed area, channel slope, and a soil infiltration index in the region east of the Rocky Mountain Foothills. In the Rocky Mountain Foothills, estimates of peak rates of runoff from ungagged watersheds can be made using watershed contributing area, elevation, and location. Design procedures for estimating peak rates of runoff in these regions are illustrated by examples. Results of the studies used to develop these design procedures are presented in summary form.reportsengCopyright and other restrictions may apply.
