Effect of effluent from wastewater treatment plants on karst rivers
Schrimpelová, Kateřina ; Gruberová, Eva (referee) ; Malá, Jitka (advisor)
Karst rivers are special type of rivers because of their hydrography conditions. They usually flow from non-karst area and as soon as they reach in to the karst area they disappear underground. There, they flow through cavities until they reach the surface again. The aim of this thesis is to assess the impact of water outflow from wastewater treatment plant on karst rivers. The study was done in the central area of CHKO Moravský kras where the impact of two WWTP on a cave system Rudické propadání – Býčí skála is evaluated. As a part of this study a half-year monitoring was carried out, which consisted of water sampling once every two weeks. In total, 13 water samples were taken from 8 sampling points. Also 4 additional one-time samples were taken from the cave system. Moreover, flow rate, temperature, conductivity, oxygen concentration and pH were measured at the sampling point. Afterwards, the content of undissolved solids, CODCr, BOD, N-NH4+, N-NO2-, N-NO3-, P-PO43- and total phosphorus were determined in the samples. The change of parameters in time and during the flow in the river was observed from the measured values. The balance of pollutants in particular parts of the river was calculated. The outflow values from waste water treatment plants were compared to the emission limits for surface waters and the parameters of rivers were compared to the environmental quality standards. According to the results, it can be observed that the water quality improves after passing through the cavities. It was proven that the outflows from the observed waste water treatment plants are negatively influencing the water streams. The most serious problem is the wash up of sludge from WWTP Rudice and its consequent sedimentation in the river and/or outflow to the Rudické propadání.

Assessment of runoff conditions on flow in the Morava river basin
Holá, Lucie ; Niklová, Věra (referee) ; Uhmannová, Hana (advisor)
The diploma thesis deals with the design of nature close to the flood protection of the city Prostějov at the confluence of the watercourses Romže and Hloučely and the flow Valova (Romže). In canculations there was solved capacity of individual sections and canculation of levels for one-year, five-year and twenty-year flow. For canculations there was used one-dimensional mathematical model HEC-RAS 5.0.3. Determination of roughness of bottom and slopes was based on personal visit. The result of this diploma thesis is evaluation of current state and proposal of a nature close to the flood protection in the individual streams in the city Prostějov. The thesis contains the calculation part and the drawing part documenting the proposed measure.

Water conservation measures to slow down the runoff and increase the water supply in the floodplain of Kozí stream
Blatecká, Markéta ; Komendová, Denisa (referee) ; Hyánková, Eva (advisor)
This thesis deals with the variety of measures in the floodplain of the piped Kozí creek, which aim to improve its morphological and ecological condition, slow down the runoff from the basin and increase the retention capacity of its surroundings. The thesis contains theoretical knowledge about revitalization, renaturation and restoration of water reserves in the landscape, which is then applied to concrete solutions. Associated with this topic is also the drainage of the landscape and an assessment of historical drainage interventions from a contemporary perspective, within which the thesis addresses theoretical and practical dealings with drainage structures that are no longer needed or no longer functional. The thesis includes the implementation of watercourse monitoring according to the HEM methodology, which serves as a tool for assessing the hydromorphological condition of watercourses. The evaluation of the monitoring is then used for the design of individual measures.

Effects of Municipal Wastewater Treatment Plant at Lopac Sinkhole Cave System
Ondruš, Martin ; Gruberová, Eva (referee) ; Malá, Jitka (advisor)
The aim of this thesis is to assess the impact of water outflow from wastewater treatment plant on karst rivers. The study was done in the northern area of Moravský kras protected landscape, where the impact of WWTP Ostrov u Macochy on a cave system Lopačské propadání was studied. As a part of this study a half-year monitoring was carried out, which consisted of water sampling every two weeks. In total, 13 water samples were taken from 7 sampling points. Moreover, flow rate, temperature, conductivity, oxygen concentration and pH were measured at the sampling point. Afterwards, the content of undissolved solids, COD, BOD, N-NH4+, N-NO2-, N-NO3-, NKi and total phosphorus were determined in the samples. The change of parameters in time on the sampling points and further along the flow of the river was evaluated from the measured values. The outflow values from waste water treatment plants were compared with the emission limits for surface waters and the values of river water parameters were compared with the environmental quality standards. It wasn’t proven that the outflow from the observed waste water treatment plant is negatively influencing the water stream. The most serious problems are: -The WWTP was designed for treatment of sewage from Ostrov u Macochy, which involved separate sanitary and storm sewers. After finishing the WWTP, a uniform sewer was built. -High concentration of total phosphorus on the outflow from WWTP. -Poor quality of Lopač brook water already before the outflow vent from WWTP.
