Research Project: MODELING SNOW, SOIL MOISTURE, AND STREAMFLOW IMPACTS ON WATER, SOIL AND VEGETATION RESOURCES IN SEMI-ARID BASINS

Location: Northwest Watershed Management Research

Project Number: 2052-13610-010-02
Project Type: Specific Cooperative Agreement

Start Date: Sep 30, 2008
End Date: Sep 29, 2013

Objective:
1. Evaluate how snow deposition, energy balance and melt rates vary with site conditions such as elevation, topographic structure and vegetation cover. 2. Use high resolution remote sensing of terrain and vegetation structure to improve characterization of landscape features and condition. 3. Continure testing, evaluation, validation and improvement of meterologic, hydrologic and snoe models. 4. develop a modeling strategy for extending point and catchment-scale results to larger areas and regions.

Approach:
This project will involve collaboration between ARS and University of Idaho scientists to: a. extend the surface energy balance and flux measurement efforts to evaluate growing season conditions; b. continue software testing and development for meteorological, hydrologic and snow modleing; and c. analysis of recently acquired OWLX LiDAR data, including development of specific products, and modification of simulation model structures.
