Master's thesis

Flood Risk Assessment for the Selected Stationing of Odra river II.

Abstract:

The task of this thesis is to apply the methodology of flood risk and hazard maps for the selected Odra river section flowing through the city of Ostrava and Bohumín, which were flooded by the river, mainly in the summer of 1997 and May of 2010. In the thesis there is detailed methodology description from theoretical as well as practical point of a view. For culminating overflows modelling there was used a software tool HEC-RAS in which I created a model for 1D culminating overflows Q5, Q20, Q100 and Q500. Further, I processed the results from the hydraulic model in the program ArcMap 10.1 and created flood hazard and flood risk maps in it.

Abstract:

Úlohou tejto práce je aplikovať metodiku tvorby máp povodňového rizika a nebezpečenstva na vybraný úsek Odry pretekajúcej cez mestá Ostrava a Bohumín, ktoré boli touto riekou zaplavené a to hlavne v lete roku 1997 a v máji v roku 2010. V práci je podrobne popísaná metodika ako z teoretickej tak aj z praktickej stránky. Na modelovanie kulminačných prietokov bol použitý programový nástroj HEC-RAS v ktorom som vytvoril 1D model pre kulminačne prietoky Q5, Q20, Q100 a Q500. Výsledky z hydraulického modelu som ďalej spracoval v programe ArcMap 10.1 a vytvoril v ňom maticu povodňového rizika a samotné mapy povodňového nebezpečenstva a povodňového rizika.
