Burda, Jan ; Hradilek, Václav (advisor) ; Bašta, Petr (referee)
This thesis deals with a measure bathymetry small water reservoirs Kala in the basin of Litovicko-Šárecký brook using a measuring instrument RiverSurveyor M9, and evaluation of measured depths in the form of a digital terrain model of the reservoir floor and the determine the accumulation of the small water reservoir. The theoretical part deals with small water reservoirs in general, ways of clogging and bathymetry. It also describes the location of interest small water reservoir Kala. There are also describes the interpolation methods and a digital terrain model. Included are basic information about the measuring instrument RiverSurveyor M9, which were measured. In the practical part describes the procedure for measuring of the reservoir floor. Furthermore, it is processed by a digital terrain model, including an evaluation of reservoir accumulation. For the creation of a digital terrain model is used several interpolation methods, which are then compared to each other. Among the comparison methods include IDW, Kriging, Topo to Raster, Spline, and Natural Neighbourhood Trend. Have proven IDW method that achieves the best results.
