Abstract:
|
"IWMI requested the author to develop a computer model (PLANWAT) for use in its research projects and in collaborative action research projects with other organizations. PLANWAT is a computer model that uses the single crop outputs of SAPWAT, combines them into a cropping system and calculates irrigation requirements for that system. It is suitable for use on a range of systems, from 10 m2 to several million hectares. For small areas, it links to a water-harvesting module that estimates required runoff areas and minimum storage volumes. It is expected that this computer program will be useful for those who manage irrigation water on farms and in irrigation systems, and for those who design water storage facilities for farms. The printed version includes a CD-ROM."
