Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to 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.
In the aquifer, groundwater flows from points of higher pressure to points of lower pressure, and the direction of groundwater flow typically has both a horizontal and a vertical component. The slope of the water table is known as the “hydraulic gradient”, which depends on the rate at which water is added to and removed from the aquifer and ...
The vadose zone, also termed the unsaturated zone, is the part of Earth between the land surface and the top of the phreatic zone, the position at which the groundwater (the water in the soil's pores) is at atmospheric pressure ("vadose" is from the Latin word for "shallow").

Agricultural water management in the Philippines is primarily focused on irrigation. The country has 3.126 million hectares of irrigable land, 50% (1.567 million hectares) of which already has irrigation facilities. 50% of irrigated areas are developed and operated by the government through the National Irrigation System (NIS). 36% is developed by the government and operated by irrigators ...

According to the New York Times, here's exactly how to play Strands: Find theme words to fill the board. Theme words stay highlighted in blue when found.
Precipitation and infiltration recharge the groundwater with an island. If rainfall recharge of an island aquifer is significant, the seepage zone might form and shift the interface towards the sea. Ghijben – Herzberg Principle can be used to estimate the depth of groundwater. [16] Confined Continental Coastal Aquifer
