Climate-induced precipitation spikes demand modern civil hydraulic designs that move beyond undersized heritage drainage networks.
Using Intensity-Duration-Frequency (IDF) curves and the Rational Equation Q = C·I·A, peak runoff discharges are computed for catchment basins with increasing impervious paved surfaces.
Culvert Hydraulics: Inlet vs Outlet Control
Accurately diagnosing whether a box culvert operates under inlet control (critical depth at entrance) or outlet control (tailwater submerged barrel) dictates headwater elevation and prevents highway embankment overtopping.
