Abstract
The paper discusses the possibilities to evaluate the effects of applying different criteria for design of surface drainage systems on the reliability of these systems. The reliability is expressed using the safety faktor for surface drainage, which is defined in the paper as the product of the hydrologic safety faktor (reflects the relation between the design storm frequency and the actual storm frequency) and the hydraulic safety faktor (defined here as inlet efficiency). An example is given to demonstrate the evaluation of safety factors in surface drainage design for a hypothetical catchment that consists of a two-lane pavement with associated sidewalk, with considerations related to inlet capacity and spacing.
U radu se prikazuju mogućnosti procene efekata primene različitih kirterijuma za projektovanje sistema za odvođenje površinskog oticaja od kišnih voda na pouzdanost tih sistema. Pouzdanost je iskazana preko koeficijenta sigurnosti za odvođenje površinskih voda, koji je u radu definisan kao proizvod hidrološkog koeficijenta sigurnosti (odnos verovatnoće pojave računske i stvarne kiše) i hidrauličkog koeficijenta sigurnosti (ovde definisanog kao efikasnost slivnika). Prikazan je primer kojim se ilustruje određivanje koeficijenta sigurnosti pri projektovanju odvođenja kišnih voda za hipotetički sliv koji se sastoji od kolovoza sa dve saobraćajne trake i pripadajućeg trotoara, i u kome se razmatraju kapacitet slivnika i rastojanje između slivnika.
