Bathymetry of water reservoirs in the Czech Republic

The remote sensing of water reservoirs is not common in the Czech Republic. At the present moment modern technologies are partially used for the large water reservoirs and the navigable parts of Czech rivers. Mostly there is just one measuring technique used and often not to its full potential. Most of the new measuring techniques of bathymetry are designed for the marine ecosystems. This thesis analyzes them and comes up with their possible use including their limits in the conditions of the water reservoirs and rivers in the CR. Those limits arise from geomorphology, volume, area, depth, water quality and bottom structures. At the present time it is possible to deduce from the measuring the character of bottom structures, this option has not been taken advantage of in the CR yet. The selection of the suitable sediment measuring technique, which is derived from the material composition of the bottom, is also discussed in this thesis. The result of the bathymetric measuring are the point datasets which are by the selected mathematical models transformed into connected areas with the as much reliable as possible representation of the bottom surface. In the end of the thesis selected mathematical models are discussed from the perspective of their applicability to different geometry and density of input data with the file of statistical indicators such as RMSE, MAE, ME
