The article analyses the current state of flood protection of the urban area in the foothill region. Problems of the area were characterized through selected critical points that support the local flood origination. Of course, the flood is a random phenomenon and its behaviour depends on many other factors, such as soil saturation, vegetation cover, river bed channel current state, as well as drainage cuts, soil management, etc. For efficient design of the flood protection measures, it is necessary to have input data with a high degree of reliability. This is usually not ensured in such small regions because hydrological and precipitation data from gauging and precipitation stations are missing. Therefore, before the design of the flood protection measures, the inputs themselves (mostly hydrological) are simulated, which is a demanding process and the results have a high degree of uncertainty. In this paper, different outputs of flood hydrographs modelled in different methods are presented and compared. The hydrograph is used then as a direct input for the design of the flood protection measures. Therefore, the degree of its reliability affects the whole proposal not only from the economic point of view but mainly from the aspect of protection of the adjacent area.
