PULSE: Model-Estimated Ground-Water Recharge and Hydrograph of Ground-Water Discharge to a StreamEntry ID: USGS_PULSE
Abstract: The computer model PULSE can be used to construct a hydrograph of groundwater discharge to a stream. The model is applicable to a groundwater flow system that is driven by areally uniform recharge to the water table, and in which groundwater discharges to a gaining stream. One of the two formulations used by the model allows for an instantaneous recharge pulse and subsequent groundwater discharge to the stream. The other formulation, which allows for a gradual hydrologic gain or loss term in addition to the instantaneous pulse, can be used to simulate the effects of gradual recharge to the water table, groundwater evapotranspiration, or downward leakage to a deeper aquifer.
