2009/10/29
To alleviate the pollution in the Oslofjord region it is planned to transport wastewater
to a central treatment plant by a 35 km tunnel system. The objective of the
study was to analyze the conseque...
Urban Runoff Peak Frequency Curves
Urban Runoff Peak Frequency Curves
font style='font-size:12px;'>
2009/10/28
Runoff peak frequency curves were derived from runoff flows observed in an
urban test catchment and from runoff flows simulated for storms selected from
two rainfall records. The first record, of a ...
