The influence of agricultural activities on selected physical and chemical parameters of surface water
MIKEŠOVÁ, Aneta
The aim of this diploma thesis was a statistical evaluation of the impact of farming methods and the land cover on hydrochemical parameters of surface waters drainage patterns in Novohradské mountains and identify the possible impact of agriculture on the valuesof these parameters. The area for the evaluation is consist of lower and upper parts of the basin of Pasecký, Bedřichovský and Váčkový stream. Sampling sites include agriculturally cultivated land, but also forest ecosystems. The work is mainly focused on the following parameters: conductivity, nitrate nitrogen (N-NO3-), suspended solids (NL105) and phosphate phosphorus (P-PO43-), which are parameters causing eutrophication of water. The parameters changes were analysed for the years 2014 - 2017. Significant differences were observed in the all three streams in the water chemisms between upper and lower parts of the watersheds of conductivity and nitrate nitrogen (N-NO3-). The results confirmed that the farming has a significant influence on the water quality in the Pasecký, Bedřichovský and Váčkový stream although it is an extensive farming.

Management of agricultural landscape and its impact on ion concentrations in running water
MIKEŠOVÁ, Aneta
The aim of this thesis was to compare chemical and physical parameters of surface water drainage patterns in Novohradské mountains and identify the possible impact of agriculture on the values of these parameters. Were used data for 2015 and 2016. Sampling sites include agriculturally cultivated land, but also forest ecosystems. The work is mainly focused on the following parameters: conductivity, pH, alkalinity, NO3-N and PO4-P, which are parameters causing eutrophication of water. The difference between the upper closures flows in forest ecosystems and lower closures flows near the agriculturally cultivated land has been contradictory. Conductivity values clearly showed that agricultural activity deteriorating water quality because conductivity at lower closures flows was sometimes three times higher than conductivity in the forest ecosystems, but for example, the value of PO4-P concentrations were higher at the upper closures flows, ie in forest ecosystems.

Historical-geographical aspects of the population development of the town of Třeboň
MIKEŠOVÁ, Aneta
The thesis deals with long-term population development of Třeboň and historical-geographical aspects that influenced its course. The introductory section describes the objectives and hypotheses. The next section is devoted to the discussion of literature and methodology. The thesis begins with the introduction of the town and county from the geographical, social and historical perspective. Further there is analytical processing of population development of Třeboň and other selected settlements, where the author tries to explain the determinants of the increase or decrease of population at predetermined periods. These findings are summarized in the synthesis, which generalize the trend of development and discuss in detail the various historical-geographical aspects. The final chapter assesses the achievement of the objectives and the trueness of hypotheses. The work is accompanied by tabular, graphical and map outputs.
