Potential of Napier Grass in Preventing River Siltation Associated with Water Runoff

River serves as an important element of water resources and that preventative measures from pollution are required to keep it in sustainable manners. The application of vegetative barrier as a soil conservation approach has been getting much global attention due to its advantages in terms of inexpen...
