Abstract
Urban stormwater hydrographs with various
degrees of detention and infiltration were routed through 30
hypothetical drainage networks. Only infiltration reduced
flow volume. Infiltration shortened flow duration while detention
lengthened it. Both detention and infiltration reduced
peak rate of flow, but not to the degree for which they were
designed; their effectiveness varied with drainage networks
and urban hydrologic changes. These results encourage balanced
consideration of infiltration and detention for solving
specific problems of flooding and erosion in specific watersheds.
