The Hydrological Cycle
The hydrologic cycle consists of inflows, outflows, and storage. Inflows
add water to the different parts of the hydrologic system, while outflows remove
water. Storage is the retention of water by parts of the system. Because water
movement is cyclical, an inflow for one part of the system is an outflow for
another. Looking at an aquifer as an example, percolation of water into the
ground is an inflow to the aquifer. Discharge of ground water from the aquifer to a
stream is an outflow (also an inflow for the stream). Over time, if inflows to the
aquifer are greater than its outflows, the amount of water stored in the aquifer will
increase. Conversely, if the inflows to the aquifer are less than the outflows, the
amount of water stored decreases. Inflows and outflows can occur naturally or
result from human activity. The Hydrologic Cycle involves the continuous
circulation of water in the Earth-atmosphere system. Of the many processes
involved in the hydrologic cycle, the most important are
