1 : Abhishek sinha Presentation on Hydrological Cycle $ Methods of Water Conservation
2 : The water cycle(hydrologic cycle or H2O cycle), is the continuous movement of water on, above and below the surface of the Earth. H Y D R O L O G I C A L C Y C L E

4 : Transpiration Transport Rainfall Precipitation Snowmelt Runoff Surface Runoff Infiltration into Groundwater Plant Uptake Evaporation Condensation
5 : Water changes its states among liquid, vapour, and ice at various places in the water cycle. The water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere, by the physical processes of evaporation, condensation, precipitation, infiltration, runoff, and subsurface flow.
6 : THE two processes change liquid water into vapor that can ascend into the atmosphere Evaporation 90% Transpiration 10%
7 : evaporation The transformation of water from liquid to gas phases as it moves from the ground or bodies of water into the overlying atmosphere. Total annual evaporation amounts is approximately 505,000 km3 (121,000 cu mi) of water, 434,000 km3 (104,000 cu mi) of which evaporates from the oceans.
8 : transpiration Transpiration is a process similar to evaporation. It is a part of the water cycle, and it is the loss of water vapor from parts of plants.
9 : Condensation The transformation of water vapor to liquid water droplets in the air, creating clouds and fog. It can often be used to generate water in large quantities for human use. Many structures are made solely for the purpose of collecting water from condensation, such as air wells and fog fences.
10 : Precipitation Precipitation is the formation of a solid in a solution. Most precipitation occurs as rain, but also includes snow, hail, fog drip and sleet.
11 : Snowmelt runoff Snowmelt is surface runoff produced from melting snow. Water produced by snowmelt is an important part of the annual water cycle in many parts of the world, in some cases contributing high fractions of the annual runoff in a watershed. Rapid snowmelt can cause flooding.
12 : Surface runoff Surface runoff is the water flow that occurs when soil is infiltrated to full capacity and excess water from rain, meltwater, or other sources flows over the land. Surface runoff causes erosion of the Earth's surface; deposition is the depositing of erosion.
13 : Water conservation
14 : Water conservation refers to reducing the usage of water and recycling of waste water for different purposes such as cleaning, manufacturing, and agricultural irrigation.
15 : Water Usage
16 : Water conservation measures A water conservation measure is an action, behavioral change, device, technology, or improved design or process implemented to reduce water loss, waste, or use.
17 : Water Conservation Measures Rainwater harvesting High-efficiency clothes washers Weather-based irrigation controllers Garden hose nozzles that shut off water when it is not being used, instead of letting a hose run. Using low flow taps in wash basins Automatic faucet is a water conservation faucet that eliminates water waste at the faucet. It automates the use of faucets without the use of hands.
18 : Water can also be conserved by landscaping. By changing behavior, such as shortening showers and not running the faucet while brushing teeth. Waterless car washes Utilization of Lake Water and or Sea Water for Cooling Towers Water-saving steam sterilizers, for use in hospitals and health care facilities.
19 : goals Sustainability- To ensure availability for future generations, the withdrawal of fresh water from an ecosystem should not exceed its natural replacement rate. Energy conservation- Water pumping, delivery, and wastewater treatment facilities consume a significant amount of energy. In some regions of the world (for example, California[3]) over 15% of total electricity consumption is devoted to water management. Habitat conservation- Minimizing human water use helps to preserve fresh water habitats for local wildlife and migrating waterfowl, as well as reducing the need to build new dams and other water diversion infrastructure.
