Field drainage management

Presented at the 2002 USCID/EWRI conference, Energy, climate, environment and water - issues and opportunities for irrigation and drainage on July 9-12 in San Luis Obispo, California.Includes bibliographical references.The Colorado State University Irrigation and Drainage model (CSUID) is a decision support system (DSS) that helps design and/or manage irrigation and drainage systems, which maintain crop productivity while controlling drainage return flows. CSUID includes components for irrigation scheduling; root growth calculations; flow and transport in unsaturated and saturated zones; drain discharge; and crop yield estimates. The DSS runs on a PC with Windows 95/NT. Data for the model is currently being collected from four fields in Colorado's Arkansas River Basin
