- Dr. Overeem's research involves the development of predictive surface process models, which form a tool to quantify responses of sedimentary systems to changing environmental conditions. She uses field studies to critically assess model performance. Current field studies are in regions of rapid change; the importance of working in these regions for a global understanding of the changing environment. Current research projects involve Arctic Rivers in Greenland and Canada, but also the Ganges delta in Bangladesh. Overeem uses her modeling expertise to support the Community Surface Dynamics Modeling System (CSDMS) Facility team at the University of Colorado. CSDMS promotes the modeling of earth surface processes by developing, supporting, and disseminating integrated software modules that predict fluxes of sediments and nutrients in landscapes and their sedimentary basins. Overeem is the Education and Knowledge Transfer Specialist for CSDMS.
