Hydrodynamic separation water flow sediment
 Sajner, Pavel ; Neterda, Zdeněk (referee) ; Němec, Zdeněk (advisor)
The dissertation deals with clogging of reservoirs and ponds by redundant sediments which penetrate water system by erosion. It describes methods of extracting pond sediments. It contains measurement of dewatering of sediments on hydrocyclone and design of laboratory hydrocyclone and filter unit. In the conclusion there is design of technology of dewatering sediments which were extracted by wet method by drainage excavator. Numerical simulation of flowing in hydrocyclones is simulated in the CFX programme and dewatering technology is simulated in the CHEMCAD programme.

Obsah biogenů (N, P) ve vodě a sedimentu vybraných rybníků
 Kyselová, Martina
The thesis contains findings about ponds, their water and sediment. Further findings on the eutrophication of ponds and biogens N and P, which play the most important role in it. Part of the thesis is an experimental part for which samples of water and sediment from the Šumický horní, Zámecký, Bohuslavický I and Ráček I were taken in 2016. In the laboratory of the Department of Fisheries and Hydrobiology, the basic indicators for water quality assessment and the given indicator in Sediment were set. The results of the water analyses were compared with the requirements of Government Regulation No. 401/2015 Coll. On water quality. Based on the results of the sediment analysis, the possibility of their use in agriculture was assessed.
