The storm event water balance of urban watersheds is examined through experimental studies in Baltimore, Maryland and Princeton, New Jersey. Analyses focus on the role of urban infrastructure, rainfall variability and soil hydraulic properties in controlling runoff processes in urban watersheds. The Dead Run (14.3 sq. km.) and Moores Run (9.1 sq. km.) watersheds in Baltimore and Harry's Brook (6.7 sq. km.) watershed in Princeton are the study watersheds used for examining the urban water balance. The Dead Run watershed has a nested network of 6 stream gages at basin scales ranging from 1.2 sq. km. to 14.3 sq. km. Analyses in Harry's Brook are based on a network of 4 stream gages. Stream gaging in small urban rivers is difficult, with particular problems arising in specifying stage-discharge rating curves for both high flow and low flow conditions. The role of measurement error in constraining analyses of the urban water balance is examined, based on analyses of direct discharge measurements and hydraulic modeling studies. Storm event water balance analyses from the study sites are used to characterize runoff production mechanisms in urban watersheds.
