Abstract Subject headings

A high resolution data acquisition technique was used to monitor stormwater runoff and losses of matter from three urban catchments in the city of Uppsala, Sweden. The landuse of the catchment areas were dominated by industry (1), apartment houses (2), and single houses with gardens (3), respectively. Battery supported data loggers with sensitive probes were used for registration outflow, temperature and electric conductivity every fifth minute during one year. The monitoring approach in this study clearly indicated the dynamics and the quality of urban stormwater. During one measurement period the precipitation was 125 mm while the runoffs from area 1-3 were 1016 mm, 267 mm and 60 mm, respectively. The much higher runoff from the industrial area indicated that wastewater was discharged to the stormwater sewer system. The high conductivity (407 mS/m) and temperature (19.5°C) of the water throughout the year were also clear evidence for this suggestion.
