WebDefinition of a River Regime. The river regime refers to the changes in a river's discharge over the course of a year in response to a number of factors. The factors affecting river regime include precipitation, temperature, evapotranspiration and the physical properties of the drainage basin. Let's have a quick look at how these factors have ... WebRelated to Flood hydrograph. Tidal Flood Hazard Area means a flood hazard area in which the flood elevation resulting from the two-, 10-, or 100-year storm, as applicable, is governed by tidal flooding from the Atlantic Ocean. Flooding in a tidal flood hazard area may be contributed to, or influenced by, stormwater runoff from inland areas, but the …
