The impact of agricultural and anthropogenic activities on Lhotický and Vitický stream in the watershed of the river Želivka
 Jakešová, Helena ; Charvátová, Helena (advisor) ; Petrů, Anita (referee)
Every small watercourse is part of the balance in nature. Human activity affects the quality and the physico chemical composition of water. Man is changing riverbeds and hydrological conditions of the environment. This bachelor thesis evaluates the chemical composition of experimental flows of the Lhotický stream and the Vitický stream of the Želivka river basin in the Křemešník Highlands. Doing field research, monitoring and evaluating the results of water samples is carried out to find the influence of human activities on the quality and composition of water. The area is anthropogenically influenced mainly by sewage water in the municipalities where sewage treatment plants are missing. Agricultural activity causes contamination along the entire length of the flow. The streams do not have a treated bed, overflowing is possible in numerous floodplains, the impact of pollution is mitigated by riparian vegetation.The monitored indicators rank the experimental flows into the lowest class. In the area, maintaining a healthy ecosystem is possible.
