4. Introduction to Watershed
• A watershed is simply the geographic area through which water flows across
the land and drains into a common body of water, whether a stream, river,
lake, or ocean.
• A watershed is an area of land and water bounded by a drainage divide
within which the surface runoff collects and flows out of the watershed
through a single outlet into a lager river ( or ) lake.

5. Introduction to Watershed

6. Introduction to Watershed Management
• The management of watershed includes all measurements that can be taken
to protect, manage, and conserve water and related land resources.
• Watershed management recognizes that the water quality of our streams,
lakes, and estuaries results from the interaction of upstream features.

7. Objectives of Watershed Management
• The different objectives of watershed management are:
• To control damaging runoff and degradation and thereby conservation of
soil and water.
• To manage and utilize the runoff water for useful purpose.
• To protect, conserve and improve the land of watershed for more efficient
and sustained production.
• To increase infiltration of rainwater.

8. Principles of Watershed Management
• Utilizing the land based on its capability.
• Protecting fertile top layer soil.
• Minimizing setting up of tanks, reservoir and lower fertile land.
• Protecting vegetative cover throughout the year.
• In situ conservation of rainwater.
• Water harvesting for supplemental irrigation.

9. Why Watershed management is needed?
• The availability of fresh water in many part of our country is declining.
• Sustainable development can only be achieved by watershed management.
• Water available from sea is negligible due to high cost of de-salination.

10. Types of Watershed Management
• Watersheds is classified depending upon the size, drainage, shape and land
use pattern.
• Macro watershed (> 50,000 Hect).
• Sub watershed (10,000 to 50,000 Hect).
• Milli watershed (1,000 to 10,000 Hect).
• Micro watershed (100 to 1,000 Hect).
• Mini watershed (1 to 100 Hect).

11. Benefits of Watershed Management
• The crops yields has increased in dry land farming.
• The soil loss due to erosion was brought down.
• The income of farmers increased considerably.
• Aquatic life (fish) were increased due to construction of ponds.
• Increase in surface and ground water availability.

12. Disadvantages of Watershed Management
• Require higher cost to build it.
• It requires regular maintenance in order to work properly.
• This type of system depends on rainfall of area.

13. Conclusion
• Watershed is an essential in day to day life, a vast range of activities of every
day life depend upon adequate supplies of water for example agriculture and
industry, power production, inland transportation, sanitation and public
health services, and so on. Therefore to provide all these activities
construction of watershed and manage is essential.
• Watershed is a geohydrological unit of land that drain at a common point.
The management of watershed provides a means to achieve sustainable land
and water management, poor watershed management is a major cause of
land and water degradation rural proverty in the world.
