This diploma thesis deals with the analysis of the factors which influence the direct drainage from the drainage area. The thesis specifically deals with the drainage area of the Kopaninský brook. Drainage is always influenced by several factors at the same time. These factors are above all climate, anthropogenic impact, underdrainage, shape and extent of a drainage area, land use, geologic structure, location and altitude of a drainage area. The direct drainage can be separated by different methods (modificated semi-graphical method, GROUND method, method of hydrogram separation, method of digitals filtres) or CN- curves can be used for calculation. This thesis used the method of CN curves to process the results of a given drainage area. In the methodical part of the thesis I reached to the creation of direct drainage maps with the utilisation of the BPEJ maps together with the input data gained by the method of CN curves. These outputs were created at different values of design rains repetition time N= 2, 10, 50 and 100 years. The volume of a direct drainage was calculated by a classic method and by a method using the ArcMap programme. Another part of the thesis was simulation of different area utilisation situations (real condition versus grassing of ploughland) and saturation of drainage area, or more precisely water content in soil (dry soil, middle dry soil, wet soil).
