Research
“Transient storage of water” is the key word in my research program. I study transient storage processes in systems at two different scales; watershed and stream/river. Processes slowing water movement though a watershed moderate flooding and impact of drought in the system. Transient storage processes in a stream play an important role in maintaining stream habitat and water quality.

My research program is developed on two primary objectives: 1) to understand mechanisms, quantity and timing at which water is temporally stored in watersheds, hillslopes, and stream/rivers by addressing physical and biological factors delaying water movement through the system, and 2) to understand the effects of water retention process on water quality and habitat quality of stream and river systems. One of my goals is to provide useful information for stream and watershed restoration through scientific research
