| flow_depth_gate | R Documentation |
Water Depth Upstream Of Gate
Description
Calculates the upstream water depth for a gate based on given discharge and gate parameters.
Usage
flow_depth_gate(a, Q, B, alpha, h2 = NULL, ret = "h0")
Arguments
a |
Gate opening height [m]. |
Q |
Discharge [m3/s]. |
B |
Gate width [m]. |
alpha |
Gate angle from horizontal [degrees]. |
h2 |
Optional. Downstream water depth [m]. Default is NULL (free flow). |
ret |
Specifies the return value. "h0" for depth only or "all" for all intermediate results. |
Value
A list containing the following hydraulic variables:
- h0
Upstream water depth [m].
- psi
Contraction coefficient [-].
- mu
Discharge coefficient [-].
- v
Flow velocity [m/s].
Examples
flow_depth_gate(a = 0.5, Q = 2.5, B = 2.0, alpha = 90)
flow_depth_gate(a = 0.5, Q = 2.5, B = 2.0, alpha = 90, h2 = 0.8)
flow_depth_gate(a = 0.5, Q = 2.5, B = 2.0, alpha = 90, h2 = 0.8, ret = "all")
