Sediment pond design (another post about)
(OP)
Background about the region where I live/work :
Statistical analysis reveal that 90% of storm event are equal or less than:
I'm trying to convince regulators (who are not hydrologists) that if you design a sediment pond based on a 2-year rainfall runoff (rainfall runoff exceeded only 10% of the time) and you try to minimize the outflow (detention over the maximum possible duration), you may get a sediment pond working 90% of the time (ok let's say 80%).
If you take care in the design process to check the area of the pond to ensure the settling of a particule of a certain size (e.g. 0.05 mm) + check the length/width ratio + minimum depth, you may increase the efficiency of this sediment pond.
They don't get this. They tell me that this kind of sediment pond will have a 60% efficiency, based on lab some test made in New Jersey.
I'm thinking of changing job :)
Statistical analysis reveal that 90% of storm event are equal or less than:
- 1 in of total precipitation
- Duration of 6 hours.
