Abstract

Applied GIS in Sediment Transport Modeling
Track: Water Resources
Authors: Calvin Creech, Travis Dahl, James Selegean

Geospatial data associated with sediment dynamics in rivers is increasingly integrated in the development of sediment budgets and sediment transport models. The Great Lakes Tributary Modeling program is a federally funded effort by the US Army Corps of Engineers that assists local governments and watershed organizations in reducing sedimentation and erosion rates in river systems. Several watershed-scale GIS models have been developed through this program that first identifies sediment sources, then models sediment transport in rivers, and finally calculates sedimentation and dredging requirements in navigation channels and harbors within the Great Lakes Basin. The GIS models are also used in the development of watershed management strategies that reduce the upland sources of sediment prior to mobilization in a fluvial active channel. Model applications include web-based GIS tools and stand-alone software that address agricultural management, forestry best management practices, low impact development, and natural resource management.
