Watershed management is the management of watershed area to achieve certain objectives. The objectives can be conservation of soil and water, regulation of stream flow regime, flood control, reduction of sediments, ground water recharge etc. the life of people in plains is directly related to management of upper watershed areas. Watershed management is closely related to forest management as the forestry practices plays a critical role in it.
The basic objectives of studying this course are:
- To introduce basic concepts of Watershed and its management.
- To clarify the close relationship of water and soil.
- To devote the practical possibilities of vegetation management for better water yield
Students will be well aware about the basic concepts of Watershed Management and applications
