Rainwater harvesting is being increasingly used to collect precipitation water. The ideas of trenches is to obstruct surface runoff from catchments and concentrate the water to be infiltrated. The collected …

Rainwater harvesting is being increasingly used to collect precipitation water. The ideas of barriers is to obstruct surface runoff from catchments and prohibit flow of the water to be infiltrated. …

Channel spreading is grouping technologies by which the wetted area of a drainage channel or river bed is artificially increased in order to enhance water infiltration to the aquifer. The …

Sand dams are impounding structures constructed above ground within intermittent river channels. During rainfall events, storm water runoff will accumulate sands and gravels behind the dam structure. This creates an artificial …

Subsurface dams are barriers of low permeability that are constructed underground. These structures reduce or stop the lateral flow of groundwater in order to store water below ground and elevate …

For dune filtration surface water is infiltrated into the dune system and after soil passage retrived by pumping on a well gallery or lower lying ponds. This process serves as …

Excess irrigation as a MAR technique is used on irrigated farmland where excess water is available and is spread over the area during dormant or non-irrigated seasons to allow for …

Ditches, furrows or drains are point or linear structures that allow for the recharge water to infiltrate to the aquifer underneath. They are usually shallow, flat-bottomed and closely spaced structures …

Flooding as a MAR technique is used on when excess river water is available during high flow season or when flood events need to be managed. The system uses passive …

Recharge dams are impermeable structures built into stream channels that store stream runoff water by creating surface reservoirs upstream of the dam. They can be either designed to recharge the …

Rooftop rainwater harvesting is being increasingly used in urban areas to collect precipitation water. Uses are manifold and include surface storage in tanks, usage for irrigation and groundwater recharge. The …

For Aquifer Storage, Transfer, and Recovery (ASTR) water is injected into the aquifer through one well and is extracted by another well located some distance away. The underground passage facilitates …

For Aquifer Storage and Recovery (ASR) a constructed deep well is connected to the targeted aquifer and is used for both water extraction and injection. This type of MAR is …

Soil Aquifer Treatment is a technology where water is recharged into the groundwater through soil percolation under controlled conditions. During percolation, natural soil filtration processes occur improving the source water …

Surface spreading and specifically infiltration ponds are among the most applied MAR techniques around the world. They are based on the retention and spreading of water over a mostly flat …

The infiltration through shallow wells, shafts or pits is usually practiced to recharge a phreatic aquifer where spreading methods cannot be applied because of the existence of a low permeability …
