In this region, through Conservation Bench Terrace (CBT), farm-rainwater harvesting can be done. In the CBT system, land is divided along the slope into 2:1 ratio. The lower 1/3rd area is levelled> for collecting runoff from the upstream 2/3rd area, which is left in its natural slope. Upper 2/3rd area is cultivated during kharif either with ...

5.2 Bench Terracing. The original bench terrace system consists of a series of flat shelf-like areas that convert a steep slope of 20 to 30 percent to a series of level, or nearly level benches (Fig. 5.2). In other words, bench terracing consists of construction of series of platforms along contours cut into hill slope in a step like formation.

The conservation bench terraces, described in Section 5.2.3, have the main purpose to hold on the level terraces the run-off from catchment areas on the uphill side. In the two most northern states of the USA where the method was tested, it was found that they also increased the amount of trapped snow, partly as a result of the terraces acting ...

The land surface will be flattened gradually by deep ploughing over the years. The spacing between riser dikes varies with the natural slope. In parallel with the siltation of sloping terraces, the riser dikes are made higher. The sloping terrace is less effective than the bench terrace in both soil and water conservation.
