King <br />Mr. B Sauer <br />Mr. J. Busch <br />University of Idaho <br />Department of Agricultural Engineering <br />Moscow, ID 83843 <br /> <br />TECHNICAL CONTACT: B. King <br /> <br />MACHINE COMPATIBILITY: MS-DOS IBM Compatible <br /> <br />DOCUMENTATION: Microcomputer program development for on-farm irrigation <br />systems planning. Research technical completion report, Idaho Water Resources <br />Research Institute. university of Idaho, Moscow ID 83843 <br /> <br />SPATIAL PRECISION: <br /> <br />TEMPORAL PRECISION: Half-monthly <br /> <br />OVERVIEW OF CAPABILITIES, ASSUMPTIONS: Models the soil-crop-system <br />interaction of on-farm irrigation systems showing inadequacies in the system <br />plan, if any. Assumes half-monthly time step is sufficient for evaluating <br />irrigation system adequacy <br /> <br />STRENGTHS: Shows soil-crop-system interactions <br /> <br />,\ <br /> <br />WEAKNESSES: No user support; requires Lotus Symphony for data entry. Does <br />not compute potential ET <br /> <br />INPUT REQUIREMENTS: Potential ET, rainfall, soil and crop characteristics, <br />water and labor availability, irrigation system components and layout, water, <br />labor and energy lost. <br /> <br />OUTPUT PRODUCED: <br />1. Adequacy of irrigation for all crops grown in rotation. <br />2. System limitations causing irrigation shortfalls. <br />3. capital and operational costs including the effects of inflation. <br /> <br />1-15 <br /> <br />\, <br />
