#trench #contour #cct #sct #swc #soilconservation Trench is a type of excavation or in the ground that is generally deeper than it is wide. Contour trenching is an agricultural technique that can be easily applied for water, and soil conservation, and to increase agricultural production. Between two trenches crops can benefit during the growing season from the subsoil water reserve gathered during the rainy season. Types of Trench:- Staggered trenching involves the excavation of trenches of shorter length in a row along the contour with interspace between them. These trenches are arranged in a straight line (staggered form). Staggered contour trenches are trenches dug in a trapezoid shape with a top width of 1.0 meters, and a bottom width of 1.0 meters, and a depth of 0.6 meters. Continuous Contour Trench (CCT) is usually used in semi-arid watersheds to conserve water and reduce soil erosion. There is still a lack of understanding of how the CCT influencer hydrological processes at a watershed scale. Continuous contour trench is dug at a right angle to the slope and are planned along contour lines. Doing so stops the water flowing downhill in its tracks by the trenches, and water percolation into the soil below is facilitated
