River regulation and design of flood protection
Gřegoř, Adam ; Julínek, Tomáš (referee) ; Duchan, David (advisor)
The bachelor’s thesis deals with designing flood protection on the watercourse Velička (tributary of the river Bečva), which is situated in the area of Hranice municipality. The flow modelling was done as 1D surface water HEC-RAS model. Two options of flood protection were designed based on the size of the flood areas that occured during flood flows Q5, Q20 and Q100. The first option did not consider the usage of Lhotka dry pond. The second option considered the usage of Lhotka dry pond, which was designed in the study made by AgPOL s.r.o. firm to the north of Hranice and which transforms flood flows. The result of the bachelor’s thesis are maps of flood areas that occured during the flood flows Q5, Q20 and Q100 after the implementation of flood protection options. In conclusion, the suitability of the flood protection options is evaluated.

Monitoring jakosti vody vybraného toku
Zálešák, Petr
The bachelor thesis focuses on the evaluation of water quality in the Velička River. The Velička is located in the Hodonín district in southern Moravia. Its total length is 40.2 km. Its source is on the western slope of Velká Javořina and flows into the Morava River near Strážnice. The water flow was monitored in eight profiles at two-month intervals for one year. The monitoring had two phases. The first phase consisted of taking a water sample and measuring some of the water quality parameters in the field using an instrument kit from Hach Company. These were indicators of pH, conductivity, oxygen content, and water temperature. The second phase was carried out in a laboratory by measuring the quality parameters from the water samples using a spectrophotometer. The concentrations of total phosphorus, sulphates, nitrate nitrogen, and chlorides were monitored. The quality of the water in the river was evaluated according to the ČSN 75 7221 standard and government regulation No. 401/2015 Coll. Total phosphorus was evaluated as the most unfavorable qualitative parameter.
