Delivery System Schedules and Required Capacities
The delivery of irrigation water to farmers from irrigation districts vary considerably from one project to another. A number of delivery schedules have been identified according to the...
Irrigation Water Management with Rotation Scheduling Policies
Rotation schedules are delivery-system oriented and represent relatively low capitol investment in system components and system management, but are not usually responsive enough to crop...
System Scheduling for Large Farming Operations
Irrigation scheduling uses evapotranspiration data to recommend the time and amount of the next irrigation on a field by field basis. System scheduling minimizes the cost of water deliveries...
Arranged Delivery Schedules
The method of delivery of irrigation water to farmers from irrigation districts vary considerably from one project to another. Rotation delivery systems usually place too many restrictions...
Demand Irrigation Schedules
This class of schedules consists of Demand and Limited Rate Demand. They need no communication system and can satisfy the on-farm needs with negligible constraint. The Demand schedule...
Structuring Distribution Agencies for Irrigation Water Delivery
The performance of an irrigation project is significantly influenced by the organization which distributes water to users. It is demonstrated that a intermediate level authority, typically...
Overview of Canal Control Concepts
An overview of terminology and philosophies of canal control, plus brief descriptions of canal automation technologies, is given. The justification given for examining control schemes...
