Research Project: EVALUATION OF LEVEL-BASIN IRRIGATION IN HIGH-RAINFALL ZONES

Location: Water Management and Conservation Research

Project Number: 5347-13000-015-01
Project Type: Specific Cooperative Agreement

Start Date: Sep 30, 2004
End Date: Sep 30, 2009

Objective:
The objective of this cooperative research project is to evaluate the performance of precision-graded, zero-slope level-basin irrigation systems as practiced in Louisiana, including seasonal water use, yield, water advance, and surface drainage (for irrigation water and rainfall) on rice and row crops (e.g., soybeans, corn, etc.) in comparison to traditional surface irrigation and precision-graded fields with slope.

Approach:
Field studies will be conducted on cooperators' farms where level-basin irrigation is being used. Field sites will be instrumented to measure flow rates into and out of the selected fields. During representative irrigation events, measurements will be made of advance, water depths at selected locations and surface drainage or recession. Farm data on yield and irrigation labor will also be collected. Where possible, field data will be compared with results from existing simulation models.
