What Are The Common Treatment Methods For Watershed Deterioration?

1.	What Are The Common Treatment Methods For Watershed Deterioration?
Answer» Contour building: Construction of narrow trapezoidal embankments (bunds) along the contours to impound water Contour trenching: EXCAVATION of trenches ACROSS the slope to break the velocity of runoff, and bunds are created DOWNSTREAM with the material dug out from the trenches Contour stone walls: STONES are dry packed across the hill slope to intercept surface runoff Bench terraces: Conversion of slopes into level steps fields FARM bunds: Constructed on agricultural land, on the contour line, to arrest soil erosion and improve soil moisture profile
