Water resource management is a very important issue from several angles such as development of water bodies for future, protection of available water bodies from pollution and over exploitation and to prevent disputes.
Why is it important to manage water resources Why are liquids instead of gas is used in hydraulic brakes.
Why are liquids used in hydraulic brakes instead of gases.
Liquids are used in hydraulic brakes because liquids cannot be compressed easily. Gases are compressible. Any object that is denser than the surrounding causes the air above the wing to travel faster than the air below the wing. Tornadoes are like giant vacuum cleaners because the air rushing into the tornado pushes objects into a tornado. This process is similar to the way dirt is pushed into a vacuum cleaner fluid.

Water-glycol Hydraulic Fluid: Water-glycol fluids contain from 35 to 60 percent water to provide the fire resistance, plus a glycol antifreeze such as ethylene, diethylene, or propylene which is non-toxic and biodegradable, and a thickener such as polyglycol to provide the required viscosity.

Examples include groundwater, rivers, lakes and reservoirs.
