Abstract Environmental response to acidic deposition results from movement of water through the ecosystem. As a part of the environmental studies for acidic deposition sponsored by the U.S. Environmental Protection Agency (EPA), hydrologic classification based on regional baseflow properties was done. To obtain the amount of baseflow, a flow separation method was developed based on the division of streamflows into baseflow and other runoff sources. Because of the differences in the flow paths and exposure duration, the two components were assumed to be associated with distinct geochemical responses. Individual annual hydrographs were analyzed using 31 separation slopes to determine the amount of baseflow. A total of 1575 streamflow stations in the Northeastern U.S. were analyzed through the access of a long-term daily stream flow data base. An interactive computer program was developed to obtain baseflow properties and other hydrologic characteristics of each station.
