Surface Water Quality Monitoring Network Optimization Comprehensive Report
Abstract: A generalized mathematical model with three parameters, P, a and b has been developed to predict surface runoff and water loss hydrographs from gagged and ungaged watersheds. The parameter P, found to be the most important by sensitivity analysis, was correlated to rainfall and watershed characteristics and time of the year in a fourier series expression with four terms. The parameter a, second in order of importance, was correlated to rainfall hyetograph characteristics and watershed area. The parameter b is expressed as a function a in a fifth order polynomial based upon Legendre approximation. The surface runoff hydrographs obtained by using the model approximation very well the observed surface runoff hydrographs consisting of one, two, and more than two peaks.; Work Order Number C-15968-WO04-11; February 24, 2006
