Hydromorphological survey and type specific reference conditions of streams
Tomšová, Zuzana ; Matoušková, Milada (advisor) ; Králová, Magdalena (referee)
The aim of Water framework Directive 2000/60/ES (WFD) is to reach a good ecological status of watercourses which consist of 3 constituents - the biological, physio-chemical and the hydromorphological state. To make these conditions equal among the various countries of the EU, the particular conditions of various watercourses are characterized as deviations from the default "reference status". The reference status corresponds to the natural (or near natural) state without any anthropogenic disturbance (or with only a minor disturbance). These disturbances mean different modification of the watercourses or ways of farming in the proximity of the inundation area. This Bachelor's Thesis studies publications as a basis for defining the hydromorphological - type specific - reference conditions in the WFD (2000/60/ES) context. Issues of classification and typology of watercourses are discussed, as well as the current legislation connected with these issues and the methods of hydromorphological survey in chosen countries. In the last section, possible hydromorphological parameters suitable for the determination of morphologically type-specific conditions are defined in Czech republic. Key words: reference condition, stream typology, ecological status, natural status, near natural status, hydromorphological...
