Abstract
This work shows a way to size and calibrate parameters of urban stormwater collection and treatment infiltration system. Its design allows collection of stormwater runoff events for a 2 year return period and infiltration time of less than a period between two critical stormwater events. Functioning of this system has been trialed with chaleng tests, loading the system with clean water, and results obtained have been used to calibrate preliminary hydrodynamic model. This model consists of two parts, one that follows water balanse in infiltration system, and second part which models the infiltration by using simplified Green-Ampt equations. Calibration of the model has been performed by using PEST methodology, and acquired parameter values have been subjected to sensitivity analysis. Conslusions obtained from the model have been used to design monitoring sollution for infitration system, which enables continues performance measurements of the system.
U radu se prikazuje dimenzionisanje i kalibracija parametara infiltracionog sistema za prikupljanje i tretman kišnice sa urbanog sliva. Sistem je dimenzionisan tako da prihvati kritične kišne epizode povratnog perioda od 2 godine i da ih infiltrira za period manji od razmaka dva uzastopna kritična kišna događaja. Funkcionisanje sistema je provereno probnim opterećenjem sa čistom vodom i ovi rezultati su iskorišćeni za kalibraciju preliminarnog hidrodinamičkog modela. Model sadrži deo koji prati bilans vode u infiltracionom sistemu i deo koji modelira infiltraciju uprošćenim Grin-Emptovim (Green-Ampt) jednačinama. Kalibracija je odrađena PEST metodologijom, a dobijene vrednosti parametara su proverene analizom osetljivosti modela. Zaključci dobijeni sa modela su iskorišćeni za projektovanje sistema za monitoring infiltracionog bazena, koji će omogućiti kontinualno merenje performansi sistema.
