Shifting Debris
The scattergraph depicted here reveals shifting debris that reduces the pipe
capacity at this monitoring location. The iso-Qs depict the average daily minimum
and maximum flow rates. As the debris accumulates, the same daily flow rates are
carried under deeper and slower conditions. The Manning Equation is applied using
the Stevens-Schutzbach Method to determine that the debris accumulation results in a capacity loss of 25.5%
