This thesis is concerned with analysis and brief evaluation of hydrological data provided by Lesy hl. m. Prahy company. Processing and assessment of data was carried out within two separate parts.

To enable this data research a modification using MS Excel application was necessary followed by formation of a script in R application. These adjustments were inevitable due to a high number of records. The data is constituted by values of the following indicators: BSK, CHSK, nitrogen nitrate, dissolved oxygen and undissolved matter, measured within a range of eleven years in various drawing profiles of fifteen Prague streams. In the second part of this work the model was created by GWR method and by experimental attainment of various factors which could hypotethically affect the quality of surface water in the capital city of Prague. By means of statistical methods existence of several places that are negatively affected by urbanizations and human activity has been proven. Out of htese places the most affected is Komoransky stream. This fact has...
