Notes:

  1. Creek flow over intake during normal operations measured in cubic feet per second or cubic meters per second.
  2. Volume of water diverted from the creek into the intake.
  3. Normal yearly flood flow conditions.
  4. Difference in elevation between the upstream weir wall and downstream wall of the collection chamber 5. This is head loss due to the Coanda intake structure. Typical Coanda head loss is between 52”-58” depending on design. A lower Coanda can be designed with a corresponding long weir length.
  5. The collection chamber is the concrete structure under the Coanda screen into which throughput water is collected and diverted to the penstock.
