13 Canal Regulation Flow Rate Constant Downstream Water Level Constant Upstream Constant Downstream Hand-On Training Constant Upstream 13

14 Simple Example Canal Check H up Q up H down Q check Q down Q out1 Q up = Q out1 + Q check + Q out2 + Q down + S Q out2 14

15 Simple Example Constant H up Goal is to Hold Upstream Water Surface Elevation Constant Change in Inflow Increase or Decrease Change in Lateral Outflow (Irrigation Turnouts) 15

16 Hands On Training 144 Flume 3 feet wide Flume Constant Head Tank 16

17 Hands On Training 4 Teams 4 Teams of 2 People 3 Teams Operating Canal Gates 1 Team Water Master 1 Person Operates Gate 1 Person Liaison with other Teams Water Master Team Controls Inflow Tommy Water User 17

18 Hands on Training Objectives and Script Objectives Keep Water Level Constant in each Reach Minimize Waste Keep Water User Happy Script (as requested by Water User) 0 to 15 minutes Charge Canal supply water to 1 turnout located in Reach 3 15 to 30 minutes 1 new irrigation goes on in Reach minutes 2 new irrigation go on in Reach 1 and 3 and Reach 4 irrigation is shut off minutes Reach 1, 2, and 3 irrigations off, Reach 4 on. Automatic Control 18

19 Team Locations and Protocol Flume Water Master Constant Head Tank Team 1 only Talks to Team 2 or Water Master Team 2 only Talks to Team 1 or 3 or Water Master Team 3 only Talks to Team 2 or Water Master Water Master Talks to All Teams and Water User Water User can talk to all Teams and Water Master 19

20 Hands On Training Water Master Adjusts Inflow to System Communicates with All Teams Takes Water Orders from Team

21 Hands On Training Canal Teams 1 person operates gate 1 person communicates with others Team 1 through 2 must hold water level in their canal reach at a gauge height of 2.0 feet Water User orders water for turnout from the Team operating section of canal where turnout is located Team 3 keep water level at 2 and minimize spill 21

22 Hands on Training - Tips Water Master 1 revolution of supply gate = about 1 cfs Fully open turnout uses about 2 cfs Maximum water supply is 20 cfs Maximum flume capacity is 10 cfs Overtopping flume equals a ditch break Canal Teams Go slow on gate changes (do not over correct) When irrigation is started be ready for large change Communicate shortages both upstream and to water master Overtopping flume equals a ditch break 22

23 Flow Measurement Mechanical Magnetic Ultrasonic Differential Pressure Exotics Laser / Radar / Turbulence / Vortex / etc. 23

24 Open Channel Flow Measurement Mechanical Price AA / Impeller (turbine) Magnetic Point Ultrasonic Doppler/Transit Time Differential Pressure Weir/Flume 24

25 Pipe Flow Measurement Mechanical Impeller / Propeller / Paddle Wheel Magnetic Insertion / Full Pipe Ultrasonic Doppler / Transit Time Differential Pressure Venturi / Orifice / Pitot Tube / etc. 25

26 Flow Fundamentals Q (flow) = V (velocity) x A (area) Area (sq.ft.) measured directly from geometry Velocity (fps) = average velocity over area Flow (cfs) = calculated Q (flow) = V dx dy Volume (ac-ft) = Q (flow) x Time (days) x Q changes with time Volume = Q dt = V dx dy dt 26
