1. WATERSHED MANAGEMENT

2. What is WATERSHED ? Watershed is defined as any surface area from which runoff resulting from rainfall is collected and drained through a common point.

3. Types of WATERSHEDS Small Watersheds ( < 250 km^2 ) M edium Watersheds ( 250 – 2500 km^2 ) Large Watersheds ( > 2500 km^2 )

4. Classification of WATERSHEDS Agricultural Watershed Wetland/marsh Watersheds Coastal Watersheds Desert Watersheds Mountainous Watersheds Urban Watershed Forest Watersheds Source : http://ecoursesonline.iasri.res.in/mod/page/view.php?id=125271
