Ecosystems Research

Yusuf Mohamoud

My research interests include hydrologic and water quality modeling at different watershed scales; impacts of land use and climate change on water availability and quality; and enhancing existing process-based watershed models, particularly the HSPF. My work also involves developing statistical modeling tools for ungauged and data-sparse watersheds. Overall, my research contributes to improving TMDL development and implementation plans for impaired water bodies. The goal is to develop models and modeling approaches that are applicable to complex watershed management issues, specifically those relating to water sustainability (quantity and quality).
