Environmental Effects of Watershed Modifications


  • David, Wilfredo P.


Watershed management is more effective when there is a relief from the population to exploit the land. Undoubtedly, such policies must be premised on a full appreciation of the interdependence and the extent of interaction of the various components of watershed ecosystems This paper defines the basic concepts and assumptions in the discussion of watershed management with the objective of providing sound physical bases for land use policies for rural and forest watershed. Related issues such as soil erosion, water quality and other hydrometereological concerns are hoped to be given future research considerations.
