CSO Discharge characterization
CSO Discharge characterization
(OP)
I have a CSO structure where I need to characterize the outflow. The chamber has a tide gate (rectangular cast iron flap gate with bronze seals). I plan to use a meter to record the depth in the CSO inlet, then characterize the flow to the interceptor with a submerged orifice equation, but I am not sure if I can characterize the tide gate outfall using a mathematical equation. Can anyone provide me with a resource to understand how to calculate the out flow? Is this a reasonable approach to define the volume of water discharging from the CSO?

good luck

BUT the headwater is variable based on the storm hydrograph, and the tailwater is variable based on time/tide period. Yikes, sounds like a complex task!
Hopefully, you just need a worse case scenario at a given tailwater, which would be reasonable for the peak period of a storm? Then, you could just set up a stage:discharge curve and route the inflow.
