Culvert hydraulics at the design discharge
Hydrology · Hydraulics · Computation
From a raindrop on the ridge to a checked culvert section.
Terrain analysis, catchment delineation, three discharge methods, the unit hydrograph and the culvert hydraulics on this screen are computed in GeoTangent's own code — the same engine runs for every structure on a corridor.

What-if — change the storm
Every number on screen recomputes: time of concentration, intensity, three discharges, unit hydrograph, critical and normal depth, headwater, velocity and the checks.
