Program Goals

Our basic objective is to improve our understanding of hydrological systems and how they are responding to changes in climate and land use.  Ultimately, our goal is to develop better strategies for protecting water resources and assessing hydrological risk (e.g., flooding, drought).

Brief Description

There has been considerable speculation about how climate change will influence terrestrial hydrology.  Changes in processes like flooding, groundwater recharge, and storm runoff have important implications for water resources.  In addition, hydrology plays important roles in biogeochemical systems controlling nutrient cycling and greenhouse gas (GHG) emissions.  Our research emphasizes improving our understanding of physical hydrology and its interactions with ecosystem processes so that we can make better predictions of how climate change will impact water resources and GHG processes.  Ultimately, our goal is to use this information to develop improved approaches for protecting water and the environment.
