Current Projects:

Lost Hills Water District: Lost Hills Drainwater Reuse Demonstration Project: A small trial to determine if drainage water can be reused on selected crops, such as pistachios, and incorporated in the District's drainage water management programs.  BACK...

U.C. Davis: Reduction of Drainage During Preirrigation by Utilizing Alternate Furrow and Sprinkler Irrigation in Cotton: A project designed to quantify the magnitude of preirrigation drainage reduction of three irrigation types including sprinkler, alternate furrow and every furrow. This study will also look at irrigation impacts on yield, distribution uniformity, salinity, seasonal irrigation efficiency, water use efficiency and cost of production.  BACK...

CSU Fresno Foundation: Educational Workshops for On-Farm Irrigation Management Advances for Source Reduction of Deep Percolation and Drainage: Training and educational workshops conducted on recent advances in irrigation and drainage management, conducted at California State University, Fresno.  BACK...

Pond Shafter Wasco RCD: Assist RCD in Reducing Agricultural Drainage Through Mobile Irrigation Management Labs: A program to assist growers with irrigation system evaluations to improve distribution uniformity and irrigation efficiency to reduce the volume of agricultural drainage.  BACK...

Cal Poly: Irrigation Systems Evaluation Course: Supports six 2 ½ day short courses for staff from irrigation/water districts, farming company staff, consultants and the general public. Courses focus on irrigation theory and practice as well as an in-field evaluation of irrigation systems.  BACK...

Pond Shafter Wasco RCD: Irrigation Management Education and Training Through the Use of Demonstration Farms: Irrigation training workshops conducted in both English and Spanish for growers and field workers. Provides practical methods of irrigation management at on-farm demonstration sites. Effectiveness of various practices will be determined through the use of a mobile irrigation lab.  BACK...

Cal Poly: Detrimental Salinity Buildup on the Periphery of the Wetted Area Caused by Subsurface Drip Irrigation Identifies factors that may lead to a detrimental buildup of salinity with subsurface drip irrigation and suggest practices that might be used to reduce or avoid salinity buildup in root zones.  BACK...

Coachella Valley RCD: Salinity Mobile Lab Mapping and Analysis: Maps the salinity profile in a given crop field to assess the performance of irrigation management. Will produce site-specific salinity management programs resulting in substantial water savings, prevention of drainage problems from over-irrigation, and increased yields.  BACK...

West Stanislaus Irrigation District: Development of Salinity Budgets for the San Joaquin Basin: Will perform a quantitative analysis of changes in aquifer salinity, and provide salinity budgets in the San Joaquin Valley Project area. Will help determine the impacts and success of the San Joaquin Valley Drainage Project.  BACK...

U.C. Davis: Using Forages to Manage Drainage Water in the San Joaquin Valley: Will develop a livestock-based production system in the southern San Joaquin Valley to use saline drainage water.  BACK...

Completed Projects 2000 -

USDA/ARS: Integrated Management of Irrigation and Shallow Groundwater in the Presence of Drains: Field demonstration at Westlake Farms of irrigation management techniques to optimize crop use of shallow groundwater.  BACK...

U.C. Riverside: Findings and Recommendations to Develop the Six-Year Activity Plan for the Department's Drainage Reduction and Reuse Program: Will compile documentation on the state of knowledge and understanding of drainage water reuse studies, research and demonstration projects. Findings will help develop a six-year activity plan for the Department of Water Resources Drainage Reduction and Reuse Program.  BACK...
