It is not good in my opinion because if we will try to recharge groundwater table by artificial flooding, definitely a large source of water will be needed for the practice. In this process the loss of huge percentage of water will happen by means of vaporization and the groundwater level of source area from which we are trying to recharge the another area with low levels of ground water will definitely affected. It is better to recharge likewise a method in rainwater harvesting.
In my opinion, recharging aquifers through the foothills should be done. In the foothills there are large permeable gravel and suitable slope. In the plain, the thick layer of clay blocks flood infiltration.
Yes it is, subject to feasibility. We have a large number of tanks in India that do not have a canal system or ayacut, but function as recharge mechanism for groundwater.
It depends on the goals of the project. If you wish to recharge the stream side shallow groundwater table and improve the riparian floodplain ecosystem, then yes, artificial flooding is important and something to consider. This is because most managed river systems operate to reduce flooding which affects the riparian ecosystem.
However, if you are talking about recharge to the deep aquifer, then artificial floods may not be the best approach as stated by others in this discussion. Natural recharge is a slow process. There are exceptions (the Edwards Aquifer in Texas and recharge in desert arroyos in Arizona), but the single best way to improve groundwater is to reduce withdrawals in the first place.
What about using pumped deep wells to recharge the aquifer? This method is used for removal of brackish water after desalination via reverse osmosis, but I see no reason why it wouldn't work with fresh water.
Actually due to the climate change water related disasters frequently increase. Which paper is focus on mitigate the drought as well as control the flooding in the area.
Yes it is possible provided the recharge area is permeable enough to allow water to penetrate to the ground water table. I know in UAE for example they recharge the ground water using injection wells.
