Evaluation of Water Quality Factors in Storm Runoff from Paved Areas

摘要: Continuous water quality measurements of storm runoff into a single road inlet have been carried out at two experimental catchments in Belgrade, Yugoslavia, and Lund, Sweden. Both sites were equipped with similar instrumentation for overland flow, turbidity, pH, conductivity, temperature. The data recorded 10-s time intervals during rainfall events. To measure suspended solids concentration, turbidity meters calibrated conditions very to the real world. A detailed description field-measuring facilities used Belgrade catchment results from both are presented. After examination possible errors measurement, only reliable statistical analysis. Event mean, extreme, aggregated values analyzed. indicate that antecedent dry weather period length has minor effect upon sediments wash-off, but it an influence conductivity.
