NeDNR has developed computer simulations to illustrate how groundwater pumping may depleteStream depletion is reduction in streamflow due to groundwater pumping in a system in which surface water and groundwater are connected. streamflow under different hydrologic systems: gaining streamA gaining stream is one where water flows from the aquifer towards the stream., losing streamA losing stream is one where water flows from a stream towards the aquifer., and disconnected streamA disconnected stream is separated from the water table by unsaturated soil or rock.. To begin, explore how a gaining stream responds to pumping.
The purpose of the first simulation is to depict the relationship between groundwater pumping and the flow of a gaining stream. Change the well location and adjust pumping, then observe how the stream depth and water tableThe upper level of the underground area in which the soil and rocks are saturated with water. respond.
Adjust the location of the pumping well using this slider or by clicking on the slider's labels.
The well can be placed at three different distances from the stream.
