Analysis of precipitation and their infiltration in the pilot area in Rijeka

Ovim radom prikazani su različiti aspekti pojavnosti oborinskih voda koja može prouzročiti ozbiljnu štetu i posljedice za vodonosnike ukoliko ih se ne zbrinjava na adekvatan način. Opisan je integralni način oborinske odvodnje koji se nameće kao adekvatno rješenje u zbrinjavanju i tretmanu istih. U radu su analizirane krivulje „Projektnog pljuska“ za grad Rijeku, s kojima su analizirani i hidrogrami otjecanja s odabrane prometnice Gornja Orehovica – Čavle. Provedene su i različite varijante dimenzioniranja upojnog bunara za odabranu prometnicu s različitim koeficijentima infiltracije, te različitim značajkama ulaznih podataka o oborinama. U radu su, za dati primjer, utvrđene kritične oborine i njihova trajanja, kao i kritične vrijednosti koeficijenata infiltracije kod kojih može doći do prelijevanja vode iz upojnog bunara.This thesis presents various aspects of rainfall occurrences that can cause considerable damage and consequences for aquifers if they are not adequately treated. An integrated method for the precipitation drainage is described as an adequate solution for their management and treatment. The Design storm curves for the city of Rijeka were analysed, which were then used to compute the runoff hydrograph from the Gornja Orehovica – Čavle road. The absorbing wells that collect the runoff from this road were designed based on several scenarios with different infiltration coefficients and precipitation input data. For this pilot area, critical precipitation heights and durations were determined, as well as critical values of infiltration coefficients for which the absorbing wells may become overflown
