is easily ACCESSIBLE FRESHWATER that can be found naturally or artificially in formations where WATER CAN ACCUMULATE, called —.

Surface water, reservoirs

Huge percentage of surface water, about 69%, is — in the form of ice caps and glaciers. It is found at the north and south poles in regions with permanent snow and permafrost (frozen soil). Most of the frozen freshwater are located in the Greenland and Arctic regions, and about 90% of it is found in —.

frozen water (solid) , Antarctica

— contain only a SMALL PORTION of Earth's water resources. They serve as an IMPORTANT SOURCE OF FRESHWATER, which is collected and stored in dams or watersheds to supply the community's water needs.

Rivers

are smaller versions of a river basin.

Watersheds

A — is made up of SEVERAL WATERSHEDS and is useful for the management of water resources. Some of the largest river basins in the world are located in Northern South America, the Amazon Basin, and the Congo-Zaire Basin in Africa.

river basin

accounts for approximately 96% of liquid freshwater.

Groundwater

It is a vital resource because it REPLENISHES SPRINGS and streams and supports wetlands.

Groundwater

is particularly essential when there is a SHORTAGE OF SURFACE WATER.

Groundwater

The —, commonly known as the —, is a natural pathway wherein WATER CHANGES between SOLID, LIQUID, AND GASEOUS PHASES through evaporation, condensation, precipitation, infiltration into the soil, surface runoff, and groundwater discharge.

hydrologic cycle water cycle

As water vapor reaches a higher altitude where the temperature is cooler, it undergoes the process of — , where it transforms into larger droplets and accumulates as clouds and fog.

condensation

As these droplets grow, collide, and become heavy, it falls as — in the form of rain, hail, or snow.

precipitation

It refers to the COLLECTION OF RAINWATER from a rooflike surface, which is then redirected to a storage, such as a tank, a cistern, a deep pit (well shaft, or boreholel, an aquifer, or a reservoir with percolation (the process of filtrating fluids through porous materials)

Rainwater Harvesting

Water collected with this method can be used for watering gardens, livestock, and irrigation With proper treatment, it can also be used domestically

Rainwater Harvesting

It is the process of directly INJECTING THE SURFACE WATER supplies such as potable water, rainwater. river water, and other reclaimed water into an aquifer (a bed/body of rock that stores groundwater) for later recovery and use by means of a well.

Aquifer Storage and Recovery

It is the progress of using HUMAN-MADE CONVEYANCES such as infiltration basins, trenches dams, or injection wells for both supplementing groundwater resources and recovering the water to add in an aquifer for various uses

Groundwater Recharge

It is USED WATER from bathroom sinks, showers. rubs, and washing machines. — may contain traces of dirt, food, grease, hair, and certain household cleaning products. While — may look "dirty," it is safe to use as irrigation water in a yard.

Greywater

It is the process of ELIMINATING CONTAMINANTS from municipal wastewater, such as household sewage and some industrial wastewater.

Sewage Water Treatment

It undergoes physical, chemical, and biological processes to GET RID OF CONTAMINANTS and produce treated wastewater that can be safe enough to be used.

Sewage Water Treatment

It is the process of using water from two different sources (groundwater and surface water) to maximize sufficient yield.

Conjunctive Use

It is a process of EXTRACTING FRESHWATER from saltwater by removing the unwanted salt content and pumping the brine water back into the ocean.

Thermal Desalination

This is considered as the popular solution to droughts and desert countries such as Arabia and Egypt. Saudi
