Project Type: Specific C/A

Start Date: Sep 25, 2003
End Date: Jun 30, 2008

Objective:
The objective of this cooperative research is to develop a suite of tools using geographic information systems and remote sensing for improved characterization of landscapes for hydrologic modeling, estimation of soil moisture, and terrain mapping, including the characterization of fluvial geomorphic characteristics. In addition, collaborative research and riparian evapotranspiration and plant water sources will be continued under this agreement due to the move of Dr. Williams from the Univ. of Arizona to the Univ. of Wyoming.

Approach:
This project is a component of a larger applied project, the goal of which is to provide the US Army with a prototype operational soil moisture modeling system based on remote sensing technology, process-based models, and geographic information (GIS) systems. The proposed approach is an integrated remote sensing and modeling system that provides soil moisture data on a daily time step and at a variety of depths at local and regional scales. The remote sensing/modeling approach will be integrated into a GIS-based assessment tool for operational use by Army terrain analysts. A rigorous validation effort is planned at four watersheds in different U.S. climatic regimes to ensure product accuracy in international application. As an applied research project, technology transfer is an integral component of this work, including development of a prototype operational soil moisture estimation system, extensive documentation, conduct of workshops and training, and publication of results in peer-reviewed literature. Dr. William's work on riparian evapotranspiration represents a continuation of joint research initiated under a specific cooperative agreement between ARS and the Univ. of Arizona to determine the water sources (groundwater, surface water, or precipitation) for riparian vegetation for a range of species and riparian water use.
