Abstract:

Irrigation water consumption in Saudi Arabia represents about 90% of the national water use, and the limited groundwater resources are the major water supply for irrigation. Improper irrigation water operation accounts for significant water losses in some large irrigation schemes. Consequently, the use of advanced techniques in irrigation operation and scheduling is essential for the reduction of irrigation water demands. A new and original Computerized and Dynamic Irrigation Water Management System (CDIWMS) was developed for automatic and/or manual irrigation operation and scheduling of irrigation schemes containing a large number of fields. The CDIWMS is supported by a comprehensive and dynamic database management system. The system performs several functions, including the dynamic modification of field information and operation conditions such as the delaying or suspension of irrigation, and the setting of fields for cutting or harvesting. The model was tested and implemented successfully in several large irrigation schemes in the Kingdom of Saudi Arabia using full automation and manual operation. The implementation of the CDIWMS has resulted in a saving of more than 25% of the water, energy and costs of operation and maintenance, and in an increase in agricultural production.
