Land use is fundamentally changing water resources. Water extraction is drawing down water tables and lowering river levels; land use change affects the partitioning of water fluxes; changes in surface runoff and aquifer recharge will affect surface water and groundwater resources; while changes in evapotranspiration may feed back to precipitation regimes. Given the interactions between different hydrometeorological processes, a systems approach is needed. This project is the first to combine both climate impacts on the hydrological regime and hydrological feedbacks on the climate.
This is accomplished by using a state-of-the-art suite of data assimilation, new process understanding, and integrated modelling of the atmosphere surface groundwater system. The set-up will be used to evaluate anthropogenic and natural changes in major water fluxes and resources for the Gangetic Plain. The northern Indian plains have experienced land use changes and water exploitation at an unprecedented scale, posing extraordinary scientific challenges to understand, quantify and predict availability of water resources.
We are focussing on the following questions:
