Simulation of ecohydrological processes influencing water supplies in the Tuul River watershed of Mongolia

Achieving sufficient water supplies for multiple uses in the watershed is a major public policy issue. Understanding the current ecohydrologic processes is essential to assess potential impacts on hydrologic regimes. The Tuul River (TR) watershed faces a cold, continental climate with water supply v...
