A lateral structure (LS) in HEC-RAS, parallel to the centerline of a river, is often used to connect a river reach to a 2D flow area, a storage area, or…
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…
Often it is necessary to re-condition a DEM by burning streams or building walls to force a watershed to be delineated with known streams or boundaries (example: NHD streams or…
Hydraulic Toolbox is a powerful tool to design riprap protection for channel banks, culvert outlets, and bridge scour countermeasures. A brief introduction about riprap is found here for general reference.…
XPSWMM is a popular 1D and 2D hydrologic and hydraulic modeling tool developed by Innovyze. Though originally XPSWMM was designed primarily to model storm sewer network system, it has gained…
A culvert is a closed conduit with a relatively short length connecting two open channels or water bodies. From a hydraulic analysis perspective, usually a culvert does NOT have too…
