This paper analyses the flow area of Pazinčica river along with its adjoining basin area. Multiple hydrological analyses and calculations were carried out with the aim of proposing as many as possible solutions for the problem of flooding of the lowest part of the Pazinčica basin during the period of high waters. The graduation thesis defines the position of the basin and its borders, geological and hydrogeological features. The current situation of the basin was determined on site, which led to better understanding of the problems in the area and possible ideas for the solution of the aforementioned problems. The analysis of data on precipitation and temperature gave an insight into the trend of these parameters during the period of several years. The study included data analysis of flow from hydrological station Dubravica – Pazinčica. The data about maximal flow and volumes of water waves for the 10, 50 and 100 year return period were calculated using hydrological calculation on predefined profiles that were suitable for building hydrotechnical structures or character evaluation of high waters all on predefined sections of Pazinčica river. The study has generated several solutions for possible flooding. Emphasis was given on construction of the accumulation pool Lipa and Rakov potok on the upper part of the basin which would in turn, providing enough water for irrigation, have a direct impact on lowering the probability of floods in the lower part of Pazinčica river basin. Additionaly, a possibility of water evacuation from the pit zone in Pazinska jama to the Draga basin was also analysed.
