H11K:
Advances in Watershed Modeling of Hydrology, Sediment, and Nutrients I


Session ID#: 10510

Session Description:
Watershed models are increasingly used to predict the effects of human activities and climate change on water quantity and quality. Such models have the potential to provide new scientific insights as well as inform critical management and policy decisions. A wide variety of models has evolved, from highly parameterized process-based models to simple, and often ad hoc, reduced complexity models. This session seeks to survey the breadth of watershed models in an effort to highlight innovative approaches, understand challenges in model development, calibration and verification, and evaluate the advantages and limitations of different approaches. We invite submissions that develop or apply common (SWAT, WEPP) as well as novel models focused on aspects of watershed scale hydrology, sediment and/or nutrient dynamics.
