Flow Measurement & Canal Operation     TBD
$90 (US) or $450 (international)

This three-day course is a series of training and educational opportunities for staff, field operators, engineers, and board members of agricultural irrigation/water districts. The classes held in San Luis Obispo utilize the excellent indoor and outdoor facilities at ITRC. Annual flow measurement and canal operations training is also offered for operators in the Chico area in cooperation with CSU Chico.


The course includes the following topics:

  • Flow Measurement - General and Pipelines: Principles of flow measurement for open and closed systems; common measurement devices - propeller, velocity head, venturi, metergate; how to take accurate readings; what to watch out for.
  • Flow Measurement - Canals: Equations for canals; weirs and flumes; corrections for common problems; current metering.
  • Canal Operations: The service concept, including farmer constraints and needs; purposes of different check structures; water level vs. flow rate control; minimizing tailender problem while still achieving good service; how to get more water through various structures; introduction to SCADA; interaction between canals and turnouts.
