Abstract |
This report describes the development and initial testing of the Watershed Erosion and Sediment Transport (WEST) Model. It is a deterministic conceptual model which operates in two phases. In the first one, hydrological and erosion processes associated with the land surfaces of a watershed are simulated, using the Agricultural Runoff Management (ARM) Model. The research work in this project centered on the second phase, in which the movement of water and sediment through a channel system is simulated using the CHANL Model. In the CHANL model the channels of a watershed are represented by a network of reaches. Hydraulic routing is performed using the kinematic wave approximation. The results are fed to the sediment algorithms which explicitly represent the processes of deposition, scour, armoring, and advection. The model is designed to handle any mixture of cohesive and cohesionless sediment. The model has been tested on laboratory data and on data from the East Fork River, Wyoming. Results from these tests were satisfactory. The model was also tested on data recorded on Four Mile Creek, Iowa. In this test, inadequate data made it impossible to draw any definite conclusions regarding model performance. |
