Rainwater harvesting (RWH) is the process of collecting and storing rainwater rather than letting it run off. Rainwater harvesting systems are increasingly becoming an integral part of the sustainable rainwater management "toolkit" [5] and are widely used in homes, home-scale projects, schools and hospitals for a variety of purposes including watering gardens, livestock, [6] irrigation, home ...
Use of groundwater, especially for irrigation, may also lower the water tables. Groundwater recharge is an important process for sustainable groundwater management, since the volume-rate abstracted from an aquifer in the long term should be less than or equal to the volume-rate that is recharged.
The reasonable use of the water by a riparian owner is subject to the downstream riparian owner's "riparian right" to receive waters undiminished in flow and quality. Federal environmental regulation of non-navigable waters under the Clean Water Act of 1972 was possible, because all surface waters eventually flowed to the public ocean.
Groundwater banking is a water management mechanism designed to increase water supply reliability. [1] Groundwater can be created by using dewatered aquifer space to store water during the years when there is abundant rainfall .
Sustainable groundwater management: the management and use of groundwater that can be maintained without causing an undesirable result. Undesirable results include any of the following: Persistent lowering of groundwater levels; Significant and unreasonable reductions in groundwater storage; Significant and unreasonable saltwater intrusion
Water resources are natural resources of water that are potentially useful for humans, for example as a source of drinking water supply or irrigation water. These resources can be either freshwater from natural sources, or water produced artificially from other sources, such as from reclaimed water or desalinated water (). 97% of the water on Earth is salt water and only three percent is fresh ...

Water located beneath the ground surface An illustration showing groundwater in aquifers (in blue) (1, 5 and 6) below the water table (4), and three different wells (7, 8 and 9) dug to reach it. Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in ...
The groundwater flow equation, in its most general form, describes the movement of groundwater in a porous medium (aquifers and aquitards). It is known in mathematics as the diffusion equation, and has many analogs in other fields. Many solutions for groundwater flow problems were borrowed or adapted from existing heat transfer solutions.
