Numerical Model of Flow in a Stream - Aquifer System

Published: 
November 5, 1974
U.S. Agency for International DevelopmentColorado State University
A three-dimensional, finite difference model was developed for simulating steady and unsteady, saturated and unsaturated flow in a stream-aquifer system. The basis of the model is the finite difference form of Richard's equation for unsaturated and saturated subsurface flow. Effects of stream...Read more

Predicting the Hydrologic Effects of Land Modification

Published: 
June 20, 1973
U.S. Agency for International Development
In summary, by comparing the "before" and "after" predicted hydrologic outputs from a coupled stochastic rainfall model and a deterministic method for estimating runoff, a procedure for comparing the hydrologic effects of land use changes on ungauged watersheds has been...Read more

Analysis and Application of a Digitally Simulated Electronic Watershed Analog

Published: 
January 1, 1972
U.S. Agency for International Development
Watershed modelers are faced with two conflicting requirements in selecting a model for the simulation of watershed hydrologic processes. The first is to select a model that is as descriptive as possible and second is to avoid over-complexity. The electric watershed analog described in this report...Read more
