Sauk-Suiattle Sediment Model

A beta version of a computational network-based sediment model was developed in order to connect processes of sediment supply on hillslopes, routing in streams, and deposition in reservoirs. The sediment model is developed in a framework called Landlab and driven by a physically-based, distributed hydrology model called DHSVM. The coupled sediment-hydrology model is designed to integrate relevant temporal and spatial scales of hillslope geomorphology, hydroclimatology and river network processes along with answering questions that are relevant to engineering application. The coupled model framework is designed to be applicable in other global watersheds, and could be useful for predicting sediment budgets particularly in the face of environmental and land use/land cover changes.

This model was developed for the Elwha Watershed, in the State of Washington.
