Separation of Floodplain Flow and Bankfull Discharge: Application of 1D Momentum Equation Solver and MIKE 21C

A floodplain is an area of low-lying land adjacent to a river, stream, or other water body that regularly inundated by during periods high flow. Floodplains typically have relatively flat terrain and are composed sediments deposited the river over time. Floodplain flow refers movement across surface This can occur as result spilling banks seeping into ground then re-emerging on floodplain. Bankfull discharge just fills channel stream top its banks. It point at which maximum capacity without overflowing onto often used reference for assessing flood risk planning management strategies. To examine bank-to-bank hydro-morphodynamics it necessary comprehend distribution throughout main Along with hydraulics, bankfull crucial parameter estimating bank erosion. For evaluating generation variety modeling tools approaches available. study investigates methods separating from observed data using one-dimensional momentum equation. two-dimensional tool (MIKE 21C) was also employed investigate usefulness proposed method in region enormous
