Hydromorphological survey and identification of reference status of the Jizera River
Tomšová, Zuzana ; Matoušková, Milada (advisor) ; Ferbar, Petr (referee)
Long-term and intensive human use of watercourses has led to their considerable degradation. Recently, there has been an effort to improve the ecological status of aquatic ecosystems, based on studies of hydromorphological characteristics of natural watercourses and identification of reference conditions. The aim of this thesis was the hydromorphological survey and an identification of reference conditions of the Jizera River. The selection of sites suitable for identification of reference status was based on pre-set criteria determined on remote sensing data, which eliminated significant anthropogenic impacts on the channel and floodplain. The survey using River Habitat Survey (Environmental Agency, 2003), Hydroecological Monitoring (Langhammer et al., 2014) and REFCON (Šmerousová a Matoušková, 2014a) methods was conducted in selected sites. Sites where hydromorphological conditions correspond with very good class, according to Hydroecological Monitoring, were used for identification of the type-specific reference conditions. Physico-chemical characteristics according to ČSN 757221 (1998) and Rosendorf et al. (2011) and the biological quality element macroinvertebrates according to Opatřilová et al. (2011) were also evaluated. Physico-chemical characteristics reached class I - II (ČSN, 1998) and...

Proposal of restoration measures in Slubice River basin based on ecohydromorphological survey
Šmerousová, Kateřina ; Matoušková, Milada (advisor) ; Just, Tomáš (referee)
This diploma thesis deals with ecohydrological state of the streams as an answer river habitat quality to exploitation, regulation and otherwise modification (flood-defence engineering, impoundment, river restoration, climate change or the spread of alien species), and with revitalization of water bodies for the purpose of elimination and mitigation of the negative consequences river ecosystem modification and improvement of ecological function river ecosystems in landscape. Focus is on the Slubice river basin in Landscape Protected Area Žďárské vrchy where field survey ecomorphological methods EcoRivHab a HEM was applied. On the basis of the obtained outputs antropogenic transformation of the river network, water quality, hydrological condition, definition of the reference state and assessment of the river patterns and changes of the length on the basis of the historical maps and ecomorphological survey outputs in the area of interest strongly antropogenic changed watercourse reaches was identified which require restoration and suitable restoration measures was proposed to the purpose of WFD goals attaining.
