Ground water level can be increased by ground water conservation and control use of water. Protect : trees, water sheds,lakes, ponds, deep drilling for water in coastal areas and water conservations.
Ground-water depletion is primarily caused by sustained ground-water pumping. Some of the negative effects of ground-water depletion include increased pumping costs, deterioration of water quality, reduction of water in streams and lakes, or land subsidence.
Groundwater is recharged naturally by rain and snow melt and to a smaller extent by surface water (rivers and lakes). Recharge can help move excess salts that accumulate in the root zone to deeper soil layers, or into the groundwater system. Tree roots increase water saturation into groundwater reducing water runoff.
The below are the plants it has good root system and can able to increase ground water level.
- Thespesia Populnea.
- Margosa tree [Neem tree]
- Banyan Tree.
Depending on its permeability, aquifers can gain water at a rate of 50 feet per year to 50 inches per century. They have both recharge and discharge zones.
Net Ground Water Recharge = Change in groundwater storage + Groundwater Extraction. Gross recharge can be determined adding base flow component of the run-off to the net recharge.
Groundwater is stored in the tiny open spaces between rock and sand, soil, and gravel. How well loosely arranged rock (such as sand and gravel) holds water depends on the size of the rock particles.
Some rain returns to the air as water vapor when water evaporates from water surfaces and from moist soil. Plant roots draw some of the moisture from the soil and return it to the air through a process called transpiration.
Industrial discharges, urban activities, agriculture, groundwater pumpage, and disposal of waste all can affect groundwater quality. Contaminants from leaking fuel tanks or fuel or toxic chemical spills may enter the groundwater and contaminate the aquifer.
The signs and symptoms of infiltration include: Inflammation at or near the insertion site with swollen, taut skin with pain. Blanching and coolness of skin around IV site. Damp or wet dressing.
Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most precipitation falls as rain.
The time it takes for surface infiltration to reach an aquifer as deep as 400 feet may take hours, days, or even years, depending on the rate of recharge. In some of the flood-irrigated areas, groundwater levels in nearby domestic wells rise within a few hours to days of flood-up.
Balance in the water cycle means the average annual precipitation over Earth equals the amount of water that evaporates. the slope or steepness of a stream channel.
Here are some very broad “rules of thumb.” The effective root zone for most plants extends down to about 3 feet. An inch of rain will wet the soil to a depth of 1 foot, if there is no runoff and the soil is a sandy loam.

Groundwater is a part of the natural water cycle (check out our interactive water cycle diagram). Some part of the precipitation that lands on the ground surface infiltrates into the subsurface. The part that continues downward through the soil until it reaches rock material that is saturated is groundwater recharge.
Water, as a vapor in our atmosphere, could potentially escape into space from Earth. While our planet as a whole may never run out of water, it's important to remember that clean freshwater is not always available where and when humans need it. In fact, half of the world's freshwater can be found in only six countries.
While your well is a 6” hole in the ground, it is not directly replenished by rainfall, as you might expect a cistern to function. With less rain, or changes in aquifer structure, the well becomes non-water bearing – i.e. dry. Your well may not 'fill up' when it rains, but it does reap the indirect benefits.
When recharge occurs in an unconfined aquifer, the water table rises to a higher elevation, much like water level in a bucket will rise as water is added to it. One inch of precipitation moving underground to the water table will cause the groundwater level to rise considerably more than an inch.
Groundwater supplies drinking water for 51% of the total U.S. population and 99% of the rural population. 64% of groundwater is used for irrigation to grow crops. Groundwater is an important component in many industrial processes. Groundwater is a source of recharge for lakes, rivers, and wetlands.
Groundwater contamination occurs when man-made products such as gasoline, oil, road salts and chemicals get into the groundwater and cause it to become unsafe and unfit for human use. Materials from the land's surface can move through the soil and end up in the groundwater.
Ninety-eight percent of Earth's available fresh water is groundwater. It is about 60 times as plentiful as the fresh water found in lakes and streams. Water in the ground travels through pores in soil and rock, and in fractures and weathered areas of bedrock.
The boundaries of a surface watershed and groundwater recharge area can, but do not always, coincide. Lakes that appear to have no major inlet are often fed by groundwater. Sometimes humans withdraw too much water from an aquifer, resulting in serious problems.
Effects on Surface WaterThe flow of water in streams and rivers declines and water levels in lakes and reservoirs drop if rainfall does not replenish these resources.
Factors Affecting Recharge RatesInfiltration and net recharge vary temporally and spatially by season, storm water intensity, stream stage, soil type, vegetation type and cover, elevation, slope, temperature, solar radiation and other factors, including the presence of buildings, paved surfaces and drainage culverts.
A watershed describes an area of land that contains a common set of streams and rivers that all drain into a single larger body of water, such as a larger river, a lake or an ocean. For example, the Mississippi River watershed is an enormous watershed. Small watersheds are usually part of larger watersheds.
Surface water and groundwater systems are connected in most landscapes. Surface-water bodies such as lakes and wetlands can receive groundwater inflow, recharge groundwater, or do both. The movement of water between groundwater and surface-water systems leads to the mixing of their water qualities.
Geology. Rainfall flows down to the rocks beneath the ground. Some rocks are permeable and allow water to flow through them. Permeable rocks can lead to less surface water.
Conserve water every day. Take shorter showers, fix leaks & turn off the water when not in use. Don't pour toxic household chemicals down the drain; take them to a hazardous waste center. Use hardy plants that require little or no watering, fertilizers or pesticides in your yard.
