Working towards better representation of Nature!

Our research group is focused on the analyses, study and development of new models and frameworks that contribute to the pool of earth system modeling. A subtle understanding of water cycle components at variable temporal and spatial scale leads to a better representation of watershed process in coupled climate and earth system models (ESM).  


A realistic runoff routing model captures temporal and spacial variability of stream flow [for example, Model for Scale Adaptive River Transport (MOSART; Li et al., 2013)] which affects water balance and other land processes in ESM. A dynamic and optimal reservoir operation rule that considers uncertainties can address non-stationarity which arises from climate change.  Similarly, reservoirs' water management has direct impact on streamflow and its temperature (Li et al., 2015). This prompts a further understanding of reservoirs, in a stratified form, to analyze the extent of their impact on stream temperature.

Physical and virtual water transfer can be analyzed through a  global water-food-energy nexus study. As the spatio-temporal distribution of water changes, it is important to look at global surface water quality and quantity by employing global river routing and stream temperature models.
