Abstract
Two watershed models were reviewed in this study on the utilization of flow
reduction factors in detention basins. The watersheds were the Middle Brook
and the Devils-Cedar Brook basins in New Jersey. A flow reduction factor set of
75%, 80%, 90 %, on average, was used in the Middle Brook Model with
ultimate flow conditions reduced to a fraction of undeveloped conditions in the
watershed. Similarly, a flow reduction factor set of 40%, 65%, 65% was used in
the Devils-Cedar Brook Model with ultimate flows reduced to a fraction of
existing conditions at the time of the study.
