Habitat Enhancement on the McCormack Williamson Tract: an Evaluation of Proposed Scenarios with a Hydraulic Model and GIS
Abstract
To support science based management decisions regarding the proposed levee breaching and habitat enhancement of a large island located in the northern Sacramento San Joaquin Delta, the McCormack Williamson Tract; a hydraulic model has been constructed, calibrated and validated. The model is used to analyze several breaching scenarios of the tract over a variety of flow conditions, ranging from purely tidal to large flood pulses. Model results for various scenarios are evaluated from both a habitat potential and a flood control perspective. An integrated approach combines results from the hydraulic model with a digital elevation model with the aid of GIS software, to provide inundation visualization and analysis for the evaluation of habitat potential. Regional flood impacts are quantified by a comparison of river stages above and below the project for the various scenarios.
