Water reservoirs are used to manage the fluctuating supply of water over long periods of time. By storing excess water when it is available, and holding it for use in times when no excess occurs, a more or less constant supply can be made available for use.

The time frame depends on several factors, many overlapping. These factors include reservoir capacities, rainfall, drought cycles, human migrations, pollution, usage rates, and anticipated future supplies and demands.
Storage capacity (reservoirs) and water management policies can buffer the supply vs. demand tension by holding and protecting water gathered in times of high rainfall to ensure that adequate supplies are available during times of drought.
Even in areas that have relatively long drought cycles, adequate supplies can usually be maintained by exercising proper management of water resources. However, water shortages occur somewhere in the world every year. Thailand is a current example.
As the world's population grows, these shortages will become more frequent and more severe. But there will be enough water for everyone for a long time if we can develop new technology and all learn to manage our existing water resources more efficiently.

What geologic process forms aquifers?
Aquifers are typically formed through the process of sedimentation and accumulation of permeable layers of rock, such as sandstone or limestone, that can hold and transmit water. Over millions of years, these layers are compacted and become saturated with water, creating underground reservoirs that can be tapped for drinking water and other uses.
What is an underground geothermal reservoir?
Over thousands of years rain water seeps through cracks in the Earth's crust and collects in underground reservoirs between the crust and the mantle. The mantle heats the water into a super-heated liquid and, voila!, you have a geothermal reservoir!
How long can a drought last?
Droughts can vary in duration, ranging from a few months to several years. The length of a drought depends on factors such as climate conditions, weather patterns, and human impacts on the environment. Long-term or "mega" droughts can last for decades, leading to severe water shortages and environmental challenges.
Where is petroleum found in ocen or ocean floor?
Petroleum is found in the ocean floor beneath the seafloor sediments. It accumulates in underground reservoirs formed by porous rocks such as sandstone or limestone. These reservoirs are typically located in offshore areas where sedimentary rocks have been deposited over millions of years.
Petroleum and natural gas are most often mined from?
Petroleum and natural gas are most often extracted from underground reservoirs located deep beneath the Earth's surface. These reservoirs can be found in porous rock formations such as sandstone or limestone, where the hydrocarbons have accumulated over millions of years. Techniques such as drilling and hydraulic fracturing are used to access and extract these resources for energy production.
Why water in reservoirs is stored for several years before further treatment?
to allow wast to settle out naturally
How is petroleum stored in ground formations?
Petroleum is stored in underground formations called reservoirs, which are typically porous and permeable rock layers such as sandstone or limestone. The petroleum accumulates in these formations over millions of years as a result of geological processes, forming reservoirs that can be tapped into for extraction through wells drilled into the rock.
What is A water shortage that goes on for several years is referred to?
A water shortage that goes on for several years is referred to as a water crisis.
Animals and plants have been using water for million years why dont we run out?
The plant has over 70% of water stored in it.
How is carbon is stored in the biosphere?
In the atmosphere carbon is stored as CO2, methane (CH4), and other organic compounds. in other word, the carbon is stored in a gigatonnes.

How long does bamboo live when submerged in water?
Bamboo can live for several years when submerged in water, typically around 2 to 5 years.
How long can RNA be stored at a stable condition without degradation?
RNA can typically be stored at stable conditions for several months to a few years without significant degradation, depending on the specific type of RNA and storage conditions.
