Welcome to the webpage of Watershed Systems Analysis and Modelling Lab.

Our focus is on developing systems theoretic approaches and tools to better understand, simulate, and predict hydrologic and water resources systems. Such systems consist of many interrelated, dynamical components working across a range of spatio-temporal scales.

Graduate students and post-doctoral fellows in the lab actively work on the different natural (e.g., rainfall-runoff, snow, permafrost, soil storage, etc.) and human-driven (e.g., reservoirs, water diversions and abstractions, agriculture, etc.) components and bring them together under a unified umbrella for the synthesis of systems behavior.

We are always interested to hear from highly-motivated individuals wishing to pursue graduate studies within our group. If you are one of them, please apply directly to Dr. Saman Razavi.
