Recharge

Science / Geology / Recharge: Water added to an aquifer or other water body. An aquifer is recharged by precipitation in an area where the aquifer has a porous connection to the surface.

Ground Water Recharge Area

Science / Geology / Ground Water Recharge Area: A location where surface water or precipitation can infiltrate into the ground and replenish the water supply of an aquifer. MORE

Recharge Area

Science / Geology / Recharge Area: The geographic area where water infiltrates into the ground and enters an aquifer. MORE

Recycling Time

Entertainment / Photography / Recycling Time: Time it takes a flash unit to recharge between firings. MORE

Palmer Drought Index

Business / Agriculture / Palmer Drought Index: A measure of the severity of prolonged periods (months or years) of abnormal dryness or wetness over large regions, published periodically by the Joint Agricultural Weather Facility. The Palmer Index MORE

Flowing Well

Science / Geology / Flowing Well: A well that taps an aquifer that is under enough pressure to force water to the surface. Caused when the aquifer has a recharge area at a higher elevation. MORE
