Development of GPS for Monitoring the terrestrial water cycle
GPS satellites transmit signals optimal for sensing water in the environment. We are developing a new method to estimate soil moisture, snow depth, and vegetation growth using GPS reflection data. Our goal is to use existing GPS networks to provide near-real time data for hydrology, climate, and ecology studies. More info>>

Estimating soil hydraulic properties using remotely-sensed data
Soil hydraulic properties (SHPs) control the partitioning of precipitation into runoff and evapotranspiration. We are investigating a modeling strategy to estimate SHPs on a continental-scale using remotely-sensed soil moisture and temperature. Our goal is to create a nation-wide map of SHPs, which will allow existing hydrologic land surface models to improve their simulations of weather, floods, droughts, and longer-term climate change.

The effects of weathering on bedrock channel erosion and form
Erosion of bedrock-floored channels is controlled by numerous factors, including channel geometry, sediment distribution, and rock properties. We are studying the effects of weathering on the erodability of rocks in stream channels, using coordinated field, laboratory and modeling efforts. More info>>
