AbstractThe aim of this research was to determine the influences of meteorological and hydrogeological factors on the water level of a rainwater storage and infiltration reservoir. The examined reservoir is located in the urban and industrial area of Krakow, on ground owned by the Polish State Railways (PKP), Kraków-Bieżanów branch. We analyzed a range of climatic (precipitation and evaporation) and hydrological factors (water stage in the reservoir and groundwater level) and their inter-relationships to determine their influences on the water depth regime in the storage and infiltration reservoir. Based on our results, the increase in the water table level in the reservoir is connected with the increase in the groundwater level and it is observed in the spring and summer periods, when meltwater and stormwater enter the reservoir. At the end of July, the groundwater table level increases because of excessive rainfall events. Throughout the entire experimental period, the reservoir was fed by infiltering groundwater from the upper parts of the basin. The water depth averages in the reservoir were closely correlated with the average groundwater table levels, the sum of precipitation from the week prior to the date of the examination of water depth in the reservoir, and the sum of potential evaporation in the given week.
