Abstract
Raster-Based Decision Support System for Determining Groundwater Availability Track: Water Resources Author(s): David Jordan, Stephen Wust, Cynthia Ardito, Van Kelley A raster-based site suitability analysis using multiattribute utility theory (MAUT) in conjunction with a MODFLOW groundwater availability model was used to determine potential supply well locations for Santa Fe County, New Mexico. Using ArcGIS Spatial Analyst, the site suitability analysis sought to identify potential supply well locations for the County that minimized impacts (and hence proximity) to existing supply wells, streams, and springs, while maximizing proximity to existing infrastructure, population centers, and areas of favorable geology and landownership using a MAUT approach. As a final step, potential supply well locations were evaluated using the MODFLOW groundwater availability model to further refine the location alternatives to identify the most promising ones. This approach provided county decision makers and the public with a structured, scientifically defensible, and unbiased method of identifying potential supply well locations. David Jordan INTERA Inc.
