Application of kinematic wave theory to estimation of runoff from selected areas of Nevada

Abstract

This thesis presents the results from efforts to implement a method of estimating runoff based on physical laws. The methodology presented involves using the kinematic wave theory in conjunction with the Soil Conservation Service curve number method of estimating runoff. The study involves relating peak flow rates, time of concentration, and design storm intensity to SCS curve number, return period, and lag modulus. The sites selected for study were Reno, Las Vegas, Tonopah, Wells and Moody Peak in Central Nevada. The results of the study are a series of graphical aids for each site showing time of concentration vs. lag modulus for a given curve number and return period; design intensity vs. time of concentration for a given return period; and peak runoff rate per unit area vs. lag modulus for a given return period. The results therefore provide guidelines for surface water hydrologists in planning and design activities.
