Irrigation Water Conservation - Benefits And Tradeoffs, Charles M. Burt
Irrigation Water Conservation - Benefits And Tradeoffs, Charles M. Burt
BioResource and Agricultural Engineering
Water conservation must be examined within the context of a water balance for a zone of specified boundaries. On-farm conservation may not result in basin conservation, and may actually damage water supplies within the basin, especially if groundwater supplies dwindle. Conservation must also take place with recognition of water rights, and therefore concepts such as Irrigation Efficiency and Irrigation Sagacity must be well understood. Because of the diversity of hydrology, there is no single menu of water management improvements which are applicable in all cases. In the future, more emphasis will be placed upon improving crop yields with a given …
Guidelines For Establishing Irrigation Scheduling Policies, Charles M. Burt
Guidelines For Establishing Irrigation Scheduling Policies, Charles M. Burt
BioResource and Agricultural Engineering
Successful on-farm irrigation scheduling requires that water delivery projects adopt a service concept, and that water deliveries be made with a high degree of reliability. An arranged delivery schedule and seasonal volumetric allocations are additional requirements. Until these conditions are met, attempts to implement modern on-farm irrigation scheduling techniques to maximize water use efficiency, and to maximize yields will be only partially successful.
Delano-Earlimart Irrigation District: Variable Frequency Drive Study, Charles M. Burt
Delano-Earlimart Irrigation District: Variable Frequency Drive Study, Charles M. Burt
BioResource and Agricultural Engineering
This report was conducted to study the pump station operation at Delano-Earlimart Irrigation District (DEID) after the installation of a variable frequency drive (VFD) control. The district is currently involved with the California Energy Commission's low-interest loan program for the installation of VFD units on their pump stations near Delano, California. Delano-Earlimart Irrigation District is a special water district organized under Division 11 of the California Water Code and encompasses 56,500 acres in Southern Tulare County and Northern Kern County. DEID has 18 individual pumping stations. DEID installed VFDs on key pumps at three different plants (D-3, D-12, and D-14).
