The diploma thesis is based on long-term monitoring of small watersheds in the Šumava region, differences and trends in the water chemistry in the years 1998 - 2015 and the differences in water balance and erosion of solutes in the years 2008 2015 are evaluated. Comparing average rainfall-runoff relationship on the catchments revealed little difference between the basins of the Horský (wetland) stream (runs off 37 %) and Bukový (forest) stream (32 %), while the basin of Mlýnský (drained pasture) creek runs off 60 % of incident precipitation. Basin of drained pastures Mlýnský - showed worsening of the parameters, which are expressed in lower proportion of water retained in the basin and also a higher proportion of dissolved solids in the effluent water. This corresponds to the overall erosion of substances from the basin, which is evident from the results, both forest and wetland basin matters detained while the drained basin is losing them for a long time. Only in the case of nitrate, ammonia, Ca2+ and Mg2+ loads from the forest and wetland basin are three times lower than the load from the drained pastures. For PO43- it is about one third less and in the case of SO42-, Cl-, K+ and Na+ it is about one half less.
