Integrating a Landscape/Hydrologic Analysis for Watershed Assessment

Abstract

Methods to provide linkages between a hydrologic modeling tool (AGWA) and landscape assessment tool (ATtILA) for determining the vulnerability of semi-arid landscapes to natural and human-induced landscape pattern changes have been developed. The objective of this study is to demonstrate the application of ATtILA and AGWA to investigate the spatial effects of varying levels of anthropogenic disturbance on runoff volume and soil erosion in the San Pedro River Basin. Results were particularly useful for assessing the effects of land cover change in the watershed and highlighting subwatersheds that require careful management.
