Locating projects in <br /> <br />relation to canal system structures and groundwater hydrology data (e,g., SDF <br /> <br />maps, saturated thickness, groundwater levels) will utilize various map layers. <br /> <br />Investigating opportunities for enhanced canal system management and <br /> <br />additional conjunctive use potential can result from a composite analysis of <br /> <br />databases representing irrigated acreage, groundwater well location, soil types, <br /> <br />and canal system layout. The use of computer based GIS (Geographic <br /> <br />Information System) applications can promote better analysis and provide <br />
