Calculate Channel Flow Depth (d) for V shaped Channel (V-ditch):

Note: Performs an iterative calculation to find the approximate depth of flow volume.

Calculation:

Designer/Checker:

Input:

Metric Units

1st side slope, rise/run (s1 - ft/ft or m/m), enter 0.0 for vertical slope.

2nd side slope, rise/run (s2 - ft/ft or m/m), enter 0.0 for vertical slope

Flow in channel (Q - ft or m)

Slope of energy grade line, rise/run, (S - ft/ft or m/m)

Manning's Roughness Coefficient (n)

Output:

Width of the water surface (w) =

Area (A) =

Wet perimeter (Wp) =

Hydraulic Radius (R) =

Flow depth, d =
