Plantation on the Ridges
Watershed interventions follow a basic principle of ridge to valley approach where very specific structures are made according to the slope.On slopes greater than 25% the only intervention possible is to protect natural vegetation and plant a variety of species native to the area.

Ridge areas are treated to arrest soil erosion in the upper part of the catchment. Simple, low cost structure like contour trenches and contour bunds slows down the velocity of run-off and improves local soil moisture profile.

 

 

 

Boulder Checks and Gabion Structures are rock dams that effectively treat small streams, trapping silts thereby protecting watershed structures downstream from siltation. They also help recharge ground water and increase the duration of water flow in the drainage line.
