How to calculate tailwater for a culvert
WebA pond is used to model a reservoir, dam, catch basin, manhole, drywell, storage chamber, vault, or other impoundment that fills with water from one or more sources and empties in a manner determined by a weir, culvert, orifice, or other outlet devices. "Zero storage ponds" may also be used to model certain storm sewers. WebNOTE: For hand computations and some computer programs, H o is assumed to be equal to the tailwater depth (TW). In such a case, computation of an exit head loss (h o) would …
