- "Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater."
The process of water seeping into the ground and replenishing the supplies of groundwater.
Hydrogeology: The study of groundwater movement and distribution in geological formations.
Aquifers: Underground geological formations that store and transmit water.
Water cycle: The continuous movement of water between the Earth's surface, atmosphere, and subsurface.
Recharge: The process by which water from precipitation and surface water enters the subsurface and replenishes aquifers.
Soil physics: The study of the physical properties and behavior of soil, including water movement and retention.
Land use and land cover change: The impact of human activities on the landscape and how it affects the recharge process.
Watershed management: Managing the use and conservation of water resources in a specific geographic area.
Geophysics: The study of the Earth's physical properties, including the use of electromagnetic and seismic methods to map the subsurface.
Hydrological modeling: The use of mathematical models to simulate the movement of water in the subsurface and predict groundwater recharge rates.
Water quality: The assessment and management of the chemical and biological characteristics of water, including its impact on groundwater recharge.
Climate change: The impact of weather patterns and climate on groundwater recharge rates.
Artificial recharge: The process of deliberately adding water to an aquifer to enhance its storage and availability.
Groundwater conservation: Practices and policies to reduce groundwater depletion and enhance recharge.
Groundwater monitoring: The continuous measurement and assessment of groundwater levels and quality over time.
Remote sensing: The use of satellite imagery and other remote sensing techniques to map and monitor groundwater recharge areas.
Groundwater hydrology: The study of the movement and distribution of groundwater, including recharge, flow, and discharge.
Water resource management: The integrated management of surface water, groundwater, and other water resources to meet a range of societal needs.
Ecological impacts of groundwater recharge: The assessment and management of the impact of groundwater recharge on local ecosystems, including wetlands and riparian areas.
Hydraulic conductivity: A measure of the ability of a subsurface material to transmit water, which affects the rate of groundwater recharge.
Groundwater contamination: The sources, pathways, and fate of pollutants in groundwater, which can impact groundwater recharge.
Direct Precipitation recharge: Groundwater gets recharged due to direct rainwater infiltration into the soil.
Indirect recharge: It happens when rainfall or other surface waters accumulate in natural areas like river valleys, depressions or artificially created water bodies like tanks or ponds and percolate into the ground.
In-channel recharge: This recharge occurs in streambeds where water from the stream percolates into the underlying aquifers.
Lateral recharge: Lateral recharge occurs due to the movement of groundwater from the adjacent highland areas to the lowland regions.
Percolation from rainwater harvesting structures: Rainwater harvesting structures like rainwater harvesting pits, percolation tanks, recharge wells and check dams help to recharge groundwater to some extent.
Managed aquifer recharge: It is a technique of recharging groundwater artificially by enhancing the natural process of infiltration.
Recharge from irrigation: It is caused by surplus irrigation water percolating into the ground.
Artificial recharge: It is done by creating structures that facilitate the infiltration of surface water into the underground aquifer.
Subsurface recharge: It involves the direct injection of water through injection wells.
Spontaneous recharge: In this type of recharge, water flows naturally from high areas to low areas due to gravity, thereby recharging the groundwater.
- "Recharge is the primary method through which water enters an aquifer."
- "This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface."
- "Groundwater recharge also encompasses water moving away from the water table farther into the saturated zone."
- "Recharge occurs both naturally (through the water cycle) and through anthropogenic processes (i.e., 'artificial groundwater recharge'), where rainwater and or reclaimed water is routed to the subsurface."
- "The most common methods to estimate recharge rates are: chloride mass balance (CMB); soil physics methods; environmental and isotopic tracers; groundwater-level fluctuation methods; water balance (WB) methods (including groundwater models (GMs)); and the estimation of baseflow (BF) to rivers."
