Project Number: 5342-13610-007-06
Project Type: Reimbursable

Start Date: Oct 01, 2001
End Date: Sep 30, 2005

Objective:
The objective of this interagency agreement with US-EPA is to improve ecosystem risk assessment via characterization research, process modeling, and via long-term monitoring studies, develop hydrological process models which can be extrapolated to larger scales. The research is designed to determine the vulnerability of semiarid landscapes to a variety of natural and anthropogenic stressors at multiple spatial scales.

Approach:
For initial funds provided within this funding period the following approach will be utilized. Conduct an evaluation of hydrologic process models suitable for multi-scale watershed assessments in the Lower Colorado River Basin. The primary evaluation factor will be the ability of the model to predict flooding (frequency, duration, and magnitude and erosion as a function of landscape composition and pattern. In addition, the ability of the model(s) to utilize large-area remotely sensed data and readily available datasets for model parameterization will be examined. A demonstration for parameterization of one or more of the models reviewed using existing datasets to illustrate the utility, issues, and uncertainties associated with the parameterization process using readily available datasets will also be carried out.
