The modified puls storage routing technique is widely used to size a detention basin by routing inflow hydrographs (Figure 1). The two unknowns, O2 and S2 , can be solved…

A storm water pump station (Figure 1) is needed in low areas of a drainage system where drainage by gravity is not possible, such as a depressed roadway segment. Pump…
A previous post introduced the design of a detention basin using Modified Rational Method in HydroCAD, and this post is about detention basin design using SCS hydrology in HydroCAD. The…
After a detention basin (a pond in HydoCAD) is added to the model and its storage is defined as explained in here, the next step is to model and design…
A storm water detention basin is usually required for a public or private development project to temporarily store excessive post-development runoff and only release the detained water through control structures…
A simple hydrograph development technique, developed by H. Rooney Malcom in 1980, is often used to design detention facilities serving relatively small watersheds (less than 640 acre or 1.0 sq…
HydroCAD and XPSWMM have the modified rational method built into the programs and it is very convenient to apply the method in either of the modeling tools. One or more…
