Normally the effects of the pond are assessed by a hydrograph routing calculation, rather than including the pond in the Tc, which cannot accurately simulate the behavior of most ponds. This means that the Tc calculation will normally end at the inflow to the pond, and the pond routing calculation will take over ...
WebThe time of concentration (Tc) is found by summing the time for each individual flow segment within the drainage area. Both single and multiple flow segments are modeled with the Tc calculator. The Tc equations provided in Bentley SewerCAD can be categorized into two broad categories: Equations that solve for velocity, then use velocity to ...
