Statement of Research Interests
My research interests include application of systems methods to identification and evaluation of models that simulate surface water and ground water flow processes
and their interaction. I give particular attention to predictions in poorly gauged and ungauged basins. Due to limited/non-existent ground-based observations at these locations, possibility of improved predictions highly depends on our ability to utilize systems methods and models to advance physical process understanding. Diagnostic model evaluation, utilizing powerful techniques to extract process relevant information from the available observations, provides a meaningful approach to constrain structure/parameters of surface water and ground water flow models. My research also involves integrating remotely sensed observations with models. Satellite-based remote sensing products provide critical information in regard to physical characteristics (i.e. vegetation pattern, topography) as well as input (i.e. rainfall) and dynamic response characteristics (i.e. inundation maps) of the watersheds. I believe sustainable management of water resources necessitates an integrated strategy that considers both surface and ground water resources. Such a strategy requires knowledge of physical processes, modelling techniques, systems methods and their integration with newly available technology.
