摘要: Meierdiercks, Katherine L., James A. Smith, Mary Lynn Baeck, and Andrew J. Miller, 2010. Heterogeneity of Hydrologic Response in Urban Watersheds. Journal the American Water Resources Association (JAWRA) 46(6):1221–1237. DOI: 10.1111/j.1752-1688.2010.00487.x Abstract: The changing patterns streamflow associated with urbanization are examined through analyses discharge rainfall records for study watersheds Baltimore Ecosystem Study (BES). Analyses utilize a decade (1999-2008) observations from dense U.S. Geological Survey stream gaging network Hydro-NEXRAD radar fields. principal watershed BES is Gwynns Falls (171 km2). Focus given to two basins contrasting histories development, Dead Run Upper Falls. sharp contrasts properties between reflect differences urban development prior implementation stormwater management regulations (much Run) which an integral part hydrologic system (Upper Falls). mean annual runoff (558 mm) 35% larger than that Falls; typify “warm season” linked storm event response. Spatial heterogeneities response reflected seasonal diurnal streamflow. presented June 2006, during monthly over region ranged less 150 more 500 mm. Baisman Run, forest reference watershed, Moores highly urbanized City, provide “end-member” representations impacts on
