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 )
Medium
Watersheds
( 250 – 2500 km^2 )
Large
Watersheds
( > 2500 km^2 )

4. Classification of WATERSHEDS

It is the process of implementing land use practices
and water management practices to protect and
improve the quality of the water and other natural
resources within a watershed.
