Popis: In my diploma thesis Evaluation of the flow Semíč and a draft measure I summarized the literature review dealing with the revitalization of watercourses and water pollution. The aim of the study was to conduct a survey of the watercourse Semíč and its water-shed. Another objective was water sampling and evaluation of selected indicators of water quality in the laboratory. Samples were taken and evaluated for the period 2013/2014 and the one calculated averages. Analyses of zinc, copper and aluminium have been performed with respect to their financial costs twice, once analysis cadmium. The results were compared with the data obtained from the 1992 and 2002/2003. The comparison of the results over time shows that some indicators marked improve-ment in contrast to certain values worsened. Results from the period 2013/2014 reflect the improving quality of surface waters. However, it is still necessary to improve the management of farmland with an emphasis on erosion, proper crop rotation and fertilizer application. In the future, it is necessary to focus on better drainage and wastewater treatment.
