Abstract : Future population increases in the Chesapeake Bay area will increase the demand for fresh water from its tributaries. A portion of this demand will be in the form of consumptive losses. In order to predict the impact of these consumptive losses on the Chesapeake Bay and future water resource programs, a study was initiated in a physical model of Chesapeake Bay to compare tide, velocity, and salinity data for a historical period of low flow with data resulting from freshwater inflow suppressed by the consumptive losses that may be expected some 50-60 years in the future. A base test simulating drought water years 1963-1966 was designed to reproduce known low-flow conditions, and a future test was designed to portray water years 1963-1966 combined with anticipated consumptive losses and diversions for 50 to 60 years in the future. Both te33sts contained a number of consecutively run, average year hydrographs to assess the bay's rebound potential following a drought period.
