| Description | The submitted thesis deals with the issue of new source of water for city Oslavany. The stream springs from left bank of river Oslava, 25 km south westerly from the Brno. City exploits few water sources but considers finding another one. Subject of research is the suitability of the spring as an additional water supply for 4700 inhabitants of the Oslavany. The introductory section is as a form of research devoted to a geology of Oslavany, the Carpathian Foredeep, Bohemian Massif, Moravikum, Boskovická brázda and history of research. The second part outlines protective zone of water resources, legislative, includes measurements of physicochemical properties, mentions CaCo3 concretions and debates possibilities of using this water source. Aim of this work is to verify water resource yield and quality of the stream described in 1990. Requested flow rate is 1 l/s. Part of this work is measuring of qualitative indicators of groundwater - pH, conductivity, ORP and temperature. 6 measurements were carried out in different seasons to assess spring variability in time. Measured flow rate is 0,5 l/s - 1 l/s and for more detailed results proper survey should be carried. There can be found CaCo3 sediments around the spring outflow, resulting from higher groundwater mineralisation. They come from limestone found on nearby field, where water infiltrates. Part of this work is to suggest protection zone of water resources. The inner zone defines strict rules and would be at close quarters of the spring. The outer zone has no harsh rules and would be the area of 1 km2. Agriculture restrictions would be needed. In conclusion, advantage is that the spring is stable with flow rate near 1 l/s. On the other hand, disadvantage is unsuitable water quality which should be treated. Stream is potentially usable. |
