What is Rain?• Rain is liquid water in the form

of droplets that have condensed from atmospheric water vapour and then precipitated—that is, a heavy enough to fall down due to gravity.

• Rain is a major component of the water cycle and is responsible for replenishing most of the fresh water on the Earth. It provides suitable conditions for the different types of ecosystems, it also provides water for hydroelectric power plants and crop irrigation.

Rain: a Rich Resource

Rain is liquid precipitation that is directly involved in Earth's dynamic weather fronts and climate classifications. It is responsible for replenishing the vast majority of fresh water on the planet, and adds up to an average global volume of 39 inches a year. Rainfall has been largely integrated into human civilization and is relied upon for the various key advantages it possesses over other means of freshwater acquisition.

1. Human Life

• Fresh water to sustain their lives.• The human digestive system needs water. • Expelling toxic substances from human body.• Water cushions the human joints.• Water reduces the human body temperature,

helps blood to flow and transport oxygen and nutrients.

• The lymph system composed of water, help to fight diseases.

2. Plants

• To survive and reproduce. • Assuring growth from seedlings to

mature stages of development. • Plants provide much needed oxygen.• Plants hold the topsoil together.

3. Natural Water Storage

• Rain water fills Aquifer which provides drinking and bathing water.

• Water in the aquifers travel though the sedimentary rock to other locations, thus providing plants and trees with a constant source of water.

• Huge amounts of rainfall over the Arctic regions drop snow, locking up trillions of gallons of fresh water in the snow sheets and glaciers.

• Rain is the main source for rivers and lakes.

4. Inundation and Flooding

• Positive effects on farmlands and delta areas.

• The flood waters transported huge quantities of silt over the banks of the rivers.

5. Electricity Generation

• Hydroelectric plants-They harness the power present in the fast-moving river water.

• Rainfall is a necessary factor in keeping enough water volume moving through the penstock pipes and turbines.

• Frequent and adequate rain keeps all of our hydroelectric plants constantly operating.

Heavy Rain: A Major Loss

More often than not, rain can become a curse also. The inconvenience it causes is well known and obvious, as in the case of weather-sensitive events. Then there's the mild depression factor, as cloudy and wet weather can dampen spirits.

1. Vegetation

• Heavy storm results in mass destruction of vegetation.

• Uprooting of trees & plants.• Decaying of plants.• Affects food availability for humans.• Destruction of animal habitat.

2. Water Quality

• A polluted environment leads to acid rain.

• Causes skin disease to humans.• Vegetation is destroyed.• Water bodies get polluted.• Sand becomes polluted.

3. Mudslides• Excessive rain following a dry period

causes Mudslides.• Mudslides erode valuable soil.• They destroy habitation and thus

can be life-threatening.• Destruction of roads and other

infrastructure.• Small trees and plants get

destroyed.

4. Flooding

• Flooding destroys homes, businesses etc..

• Flooding may lead to animal & human death.

• Flash floods are even more dangerous.

• Leads to polluted water bodies.• The National Economy is destroyed.

Uttarakhand Disaster

With the onset of the 2013 Monsoon, Uttarakhand and Parts of Himachal Pradesh in the North Western sections of India, received heavy rainfall and cloudburst

• Uttarakhand was hit by torrential rains and cloudburst. Accompanied floods and landslides.

• Caused large devastation in the state.• Many towns and villages have undergone horrendous

damage.• Roads ,bridges and several other infrastructures were

swept away.• Lead to the death of many people.

Precautions • Construction of dam.

• Construction of self closing self barrier.

• River & costal defences.

• Proper climate study.

• Systematic construction of buildings.
