Evaluation Class 1: Theory and Laboratory Practice of Evaluations (at Cal Poly)

Cost: $150

June 2024


Evaluation Class 1This first class is ITRC's traditional comprehensive 2 1/2 day class which combines classroom (50%) and outdoor laboratory (50%) activities.  Efficiency definitions and evaluation techniques are emphasized, ranging from how to take a pressure measurement to what specific measurements are needed for evaluation of six distinct irrigation methods (furrow, border strip, hand move/side roll sprinkler, linear move sprinkler, undertree sprinkler, and drip/micro). These systems can be "tuned up" to conserve water and power, and to maintain adequate surface water and groundwater qualities. The techniques and programs covered are the standard used for DWR-funded evaluation projects throughout California.

Evaluation Class 2: Field Evaluation of Drip/Micro Systems (San Joaquin Valley)

Cost: $150

June 2024


Evaluation Class 2This second class is a 2 1/2 day class where we will travel to sites in the San Joaquin Valley and perform the entire evaluations on 2 fields. The emphasis will be on performing the field evaluations for drip and microspray irrigation systems on trees/vines. This class will allow for more extensive field training to help with the comprehension of the materials from the first class.  It is highly recommended that those attending this field session attend Class 1 or have field experience doing irrigation evaluations. Note: Participants are responsible for their own transportation, hotel, and food expenses.
