Possibilities of remote geomorphological mapping of dolines in the conditions of the Bohemian Karst
Hochmanová, Lucie ; Křížek, Marek (advisor) ; Uxová, Tereza (referee)
The study of karst areas is important for the inventory of local forms and their subsequent protection. The aim of this bachelor's thesis is to create a database and determine the morphometric characteristics of dolines in the protected landscape area of the Czech Karst above DEM 5G and to evaluate the possibilities of remote mapping of these karst forms. The mapping was based on training data from the Moravian Karst, but the morphometry was found to be different from the dolines in the Czech Karst. A total of 74 dolines were found, of which 58 were mapped on DEM 5G and 16 were added from the literature. Average values of morphometric characteristics were found for length 30.34 m, width 18.65 m, depth 2.57 m and circularity 0.663. Half of them show a linear arrangement and an elongated oval shape, which may indicate a continuity with the fractures. The majority of all mapped dolines form clusters on Devonian limestones in the northwestern area of the Bohemian Karst Protected Landscape Area. As a result, two map outputs with possible locations of dolines and a database with morphometric characteristics are available. Keywords: doline, Bohemian Karst Protected Area, digital elevation model, remote sensing mapping
