H51B:
DEM-Based Watershed Hydrologic and Water Quality Modeling: Present and Future I Posters


Session ID#: 8164

Session Description:
Digital elevation models (DEMs) have been widely used for watershed hydrologic, environmental, and ecologic modeling. The selection of DEMs depends upon their acquisition techniques, resolutions, interpolation methods, etc. Those factors and DEM-based delineation methods may significantly affect the quality of related watershed modeling. This session will cover all aspects associated with DEM-based, watershed-scale water quantity and quality modeling. The topics of potential contributions may include DEM-based delineation methods, extraction of drainage networks, DEM resolution effects, scale issues and multi-scale modeling, topographic characterization and parameterization, hydrologic connectivity analysis, depression filling-spilling dynamics, and identification of runoff/contaminant contributing areas. Novel methods and techniques for improving DEM-based watershed delineation and modeling are particularly encouraged.
