The aim of the study was to analyze the possibility of using selected rainfall-runoff models to determine the design hydrograph and the related peak flow in a mountainous catchment. The basis for the study was the observed series of hydrometeorological data for the Grajcarek catchment area (Poland) for the years 1981–2014. The analysis was carried out in the following stages: verification of hydrometeorological data; determination of the design rainfall; and determination of runoff hydrographs with the following rainfall-runoff models: Snyder, NRCS-UH, and EBA4SUB. The conducted research allowed the conclusion that the EBA4SUB model may be an alternative to other models in determining the design hydrograph in ungauged mountainous catchments. This is evidenced by the lower values of relative errors in the estimation of peak flows with an assumed frequency for the EBA4SUB model, as compared to Snyder and NRCS-UH.

Vulnerability Maps

The term “vulnerability of groundwater to contamination” was introduced by French hydrogeologist J. Margat in the late 1960s. The idea of describing the degree of vulnerability of groundwater to contaminants as a function of hydrogeological conditions by means of maps was conceived to show that the protection provided by the natural environment varies at different locations. Groundwater vulnerability maps belong to category of special-purpose environmental maps and introduce one of the possible tool to solve groundwater protection. The synthetic map of relevant catchment area of Žilůvky stream was composed in the program ArcGIS as a intersection between 4 partial maps: the map of soil character according to infiltration capability, the map of geological structure according to permeability, the map of unsaturated zone potency and the map of karst phenomens, springs and boreholes localization. The final map was presented in 4 variants A – D according to meaning of layers which have the influence on groundwater vulnerability.
