Global Sediment and Water Discharge Modeling

Quantifying continental sediment flux is a fundamental goal of earth-system science. Ongoing measurements of riverine suspended sediment fluxes to the oceans are limited (<10% of rivers) and intra-basin measurements are even scarcer. Numerical models provide a useful bridge to this measurement gap and offer insight to past and future trends in response to human and environmental changes.

The WBMsed model is a spatially and temporally explicit (pixel scale and daily) global sediment flux model. It is a component within the Framework for Aquatic Modeling of Earth System (FrAMES), a spatially and temporally explicit multi-scale (local through global) hydrological/biogeochemical modeling scheme.
