Estimating Deep Percolation In The Mountain Rain-Snow Transition Zone, Patrick Richard Kormos

Boise State University Theses and Dissertations

Deep percolation (DP) is estimated from a small study catchment in the semi arid rain-snow transition zone in the foothills north of Boise, ID. A water balance is performed at the catchment soil bedrock interface, where soil drainage is assumed to be partitioned into DP and streamflow. While stream flow is measured, soil drainage must be estimated. We model the snow dynamics and surface water inputs (SWI) to the soil (Chapter 3), and the soil dynamics and soil drainage to the soil-bedrock interface (Chapter 4). The high spatiotemporal dataset used in this modeling effort is presented for the 2011 water …
