Modelování lavinového ohrožení na území CHKO Jeseníky pomocí metod DPZ a GIS
 Školoud, Libor
This diploma thesis presents a comparison of the accuracy level of elevation data and 3D elevation countours and digital relief model 5. generation. These data are used in modeling of avalanche danger Velke Kotliny on the territory of CHKO Jeseniky. In ArcGIS 10.2 software model calculations are performed of break off zones using two equations, resulting in potential break off zones. The equation is based on the same basis, but it differs in approach of their authors inclusion of horizontal and vertical curvature of the terrain. Furthermore, the equations are different with their assigned values of individual variables, which may result in changing the source data and the associated change in details and accuracy. This facet follows modeling of avalanche paths in RAMMS software (Rapid Mass Movement System), wherein the input data are crucial for simulation of individual avalanches. Distinguishing of input date significantly affects the accuracy of the simulation of avalanche paths and calculating thier final values (pressure, speed, snow depth) in individual section of their paths.
