ENVIRONMENTAL SCIENCE AND ENGINEERING

TOPICS EFFECTS OF OVER UTILIZATION OF WATER FLOODS & DROUGHT CONFLICT OVER WATER By kvk

EFFECTS OF OVER UTILIZATION OF WATER Decrease of Ground Water Ground Subsidence Lowering of Water table Intrusion of Salt water Earth quake & Landslides Drying up of wells Pollution of water

Decrease of ground water

Ground Subsidence

Lowering of water table

Intrusion of salt water

Earth quake landslides

Drying up of wells

Pollution of water

FLOODS It is an overflow of water Happens when the water exceeds the carrying limit of dams,lakes,ponds,,etc

Causes of floods Heavy rainfall,melting of snow, sudden release of water from dams. Deforestation,overgrazing,mining increases the runoff from rains and hence the level of floods raises.

FLOODS EFFECTS Water spread in surrounding areas. Plain surface became eroded and silted with mud. Extinction of civilization MANAGEMENT Constructing dams and reservoirs. Channel management, embankments also control the floods Fore casting, flood warning

DROUGHT Scarcity of water Occurs due to inadequate rainfall Failure of monsoons Excessive withdrawal of ground water

Causes of drought Annul rainfall in minimum , less than the evaporation High population Intensive cropping pattern and over exploitation of scarce water resources through dug well or bore well.

drought EFFECTS Hunger , malnutrition , scarcity of drinking water. Desertification. Degradation of natural resource Large migration of people and urbanization MANAGEMENT Rain water harvesting. Improve ground level water Modern irrigation technology

CONFLICT OVER WATER Conflicts through use Unequal distribution of water has often led to inter state or international disputes Constructions of dams Hydroelectric power generation, dams are built across the rivers, which initiates conflict between the states

Conflicts through pollution Production of electricity and shipping , rivers and lakes are also used for industrial purpose.

Management of conflicts over water Efforts are mainly concentrated to enact laws to check these practices to control water pollution. Demand of nationalisation of water needs serious consideration

Any queries?
