River Bathymetry Model Based on Floodplain Topography

Popis výsledku v původním jazyce

An appropriate digital elevation model (DEM) is required for purposes of hydrodynamic modelling of floods. Such a DEM describes a rivers bathymetry (bed topography) as well as its surrounding area. Extensive measurements for creating accurate bathymetry are time consuming and expensive. Mathematical modelling can provide an alternative way for representing river bathymetry. This study explores new possibilities in mathematical depiction of river bathymetry. A new bathymetric model (Bathy supp) is proposed, and the models ability to represent actual bathymetry is assessed. Three statistical methods for the determination of model parameters were evaluated. The best results were achieved by the random forest (RF) method. A two dimensional (2D) hydrodynamic model was used to evaluate the influence of the Bathy supp model on the hydrodynamic modelling results. Also presented is a comparison of the proposed model with another state of the art bathymetric model. The study was carried out on a reac
