Assessment of Ochozsky Brook Status
Vaculíková, Klára ; Tůma, RNDr Antonín (referee) ; Malá, Jitka (advisor)
Bachelor's thesis deals with an evaluation of Ochozský stream in the village Březina in Moravian Karst. There was done a survey of a ground and the stream surroundings. There was also gained information from the Municipal office on technical adjustment of the stream, sewer network, waste water treatment plants and polluters of Ochozský stream. Two measurements of physicochemical parameters and sampling were carried out at six sampling points in autumn 2017 and in spring 2018. Flow rate was measured at three sampling points. Conductivity, pH, temperature, oxidation-reduction potential, concentration of dissolved oxygen and saturation with oxygen were measured in situ. COD, BOD, total phosphorus, ammonia, nitrites, nitrates and Kjeldahl nitrogen were determined in water samples in the laboratory. Organic nitrogen and total nitrogen were calculated. The results were evaluated with a respect of Government Decree No. 401/2015 Coll. There was also provided a hydromorphology assessment of Ochozský stream using methodology Stream Visual Assessment. A land use of the offshore stream strip was mapped.
