| dc.description.abstract | A Compartmented Reservoir Operation Program, CROP84, is a computer program developed, by C. B. Cluff (1977), as a tool for optimizing the design dimensions of water harvesting agriculture systems. This model is used in conjunction with a rainfall /runoff model called RAMOD. The objective of the research was to compare the actual and the simulated values of seasonal irrigation and consumptive use of four crops: wheat, sorghum, cotton, and grapes. After repeated simulations structural improvements were made in the soil moisture accounting routine of CROP84. These improvements were in the equations that calculated the rate of root growth, the soil moisture depletion fraction and actual evapotranspiration. In the final simulation, the percentage difference for crop consumptive use calculated from the actual data and the simulation was +2.6 % for sorghum, -2.4 % for grapes, +2.0 % for wheat, and -8.8 % for cotton. | |
