08. Debris Amusement

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%.
