Abstract:This study involved the selection of a model that will simulate runoff, sediment yield, and channel characteristics such as bed material or cross section changes, from complex, ungaged watersheds containing various crops, soil types, slopes, channel sizes, levels of conservation management and, instream erosion control structures for long term analysis. Temporal and spatial variations of a rainfall event were also considered so the response of the watershed can be accurately modeled. Channel processes were incorporated into a comprehensive model to evaluate the effects of man-made and natural changes to the channel system. Data from the extensively instrumented Goodwin Creek Watershed in northern Mississippi was used to validate the model. The model was then used to simulate the response of the watershed to various conservation and instream erosion control management practices and the effect of these practices on the entire watershed system. The techniques used in the development of the database and modifications of the model can be used for understanding watershed management practices on other watersheds.
