WebSubsurface Utilities users need to specify the weir discharge coefficient. Typically a weir discharge coefficient ranges between 2.65 and 3.10 (English units). Since the weirs in a sewer system are mostly sharp-crested weirs, a value of 3.0 is a common default assumption without knowing the weir specifics and hydraulic conditions. WebHowever, these equations are only applicable to combined sewer overflow (CSO) structures, whose weir constructions correspond with the standard weir layout. The objective of this work is to outline an alternative approach to obtain spill flow discharge data based on measurements with a sonic depth finder. The idea is to determine the relation ...
