The NeDNR is developing a series of interactive applications about water. Please click on the links below to load the applications.
In this application, you can explore some interactions between surface water and groundwater to answer the following questions:
- How do the relative positions of the water table and stream level affect the direction of flow and rate of interaction between the stream and the aquifer?
- How does precipitation affect streamflow?
- How does soil texture (that is, whether soil particles are coarse like sand or fine like clay) affect recharge and streamflow?
Concepts addressed in this application include water table elevation, gaining and losing streams, runoff, recharge, baseflow, soil texture, and hydrographs.
Preview of Application 1
In this application you can explore the relationship between groundwater pumping and stream depletions under three hydrologic systems: a gaining stream, a losing stream, and a disconnected stream to answer the following questions:
- What are two ways in which pumping can cause stream depletions?
- How does the proximity of a well to a stream influence stream depletions?
- How do the effects of pumping on streamflow change depending on whether a stream is gaining, losing, or disconnected relative to the adjacent aquifer?
- How can pumping change the connectivity of a stream to its adjacent aquifer?
