The hydrologic and hydraulic processes that control urban flooding are examined through analyses of flood response in the Baltimore. Metropolitan area. These analyses focus on warm season thunderstorm system sand their impact on Dead Run, a 14.3 km2 tributary of the Gwynns Falls watershed, which is the principal study region of the Baltimore Ecosystem Study. Field observations of rainfall from a network of 18 rain gage stations and discharge from a network of 6 stream gaging stations have been collected during "warm season" observing periods in 2003, 2004, and 2005. Field observations are used in conjunction with the Stormwater Management Model (SWMM) to examine the spatially and temporally varying hydrological response of Dead Run. Model implementation incorporates a complete representation of the storm drain network (digitized from engineering drawings) and the network of stormwater detention basins. Analyses highlight the role of differences in density and distribution of impervious surfaces and in the urban drainage infrastructure (the storm pipe network and stormwater management facilities) for spatial heterogeneities of flood response.
