Book Description
A problem that continues to plague highway agencies is that of selecting optimum culvert sizes for waterways based on (1) estimates of the magnitude and frequency of peak flows from small rural watersheds (less than 25 square miles), (2) the relative cost of facilities necessary to accommodate the estimated flows, and (3) the possible effects of flows in excess of the estimates used for design purposes. Although this report does not resolve the problem, it does provide valuable insight into the difficulties associated with attempts to develop improved methods for estimating peak runoff rates of various return periods for small ungaged rural watersheds throughout the United States.
