Analýza mechanismu vzniku povodní v povodí Opavy po profil Opava

Abstract

Floods can be a natural disaster, which cause material and environmental damage and in the worst case even cost human lives. The main aim of many flood studies is to bring out some finding, that could be use for optimisation of flood-protection arrangements and to specify outputs of flood prediction model. This thesis study the flood mechanism in the Opava river basin down to Opava profile. Part of the thesis is the load of landscape assessment during a season and the variation of flood frequency. More detailed is analysed the period 1960-2007. Particularly is paid attention to relation between the atmospheric conditions and origin of floods in connection with the time-space distribution of the causal precipitation. By synthesis of knowledge and using method of cluster analysis were set up a categorisation of flood according to common characteristics in the causation of flood origin and a shape of flood wave. There is also the Catalogue of flood, where are characterised the conditions of atmosphere and of landscape and hydrograms of flood wave in the Opava hydrological profile.
