When boundary of bench terrace is at the contour then construction of bench terrace involves minimum earthwork, and levelling is done only in cross-wise direction. The boundary of level bench terrace is aligned along the contour line, but in case of inwardly sloping bench terraces having same bench boundary, they are executed on the longitudinal grade, facing towards outlet.

3. Contour bunding is not technically feasible on the land slopes, greater than 6%. Contour bunding is an important measure to conserve the soil and water in arid and semi-arid areas with high infiltration rate and permeability. It is commonly used on agricultural land up to 6% slope.

A contour bench, as shown in Fig. 2, consists of a cordon of earth placed just downhill of a channel, and following a contour line. This cordon is made with earthmoving machines that dig the channel, move the earth, and shape the benches. The construction of contour benches follows well-defined norms (Cherif et al., 1995). The bench length ...

The results of an experiment to monitor water and sediment balance inside a contour bench terrace system are presented. The study site, located in the El-Gouazine watershed (central Tunisia), includes two terraced plots of approximately 3000 m 2, one of which was left fallow for several years, while the other was tilled. The characteristics of ...

A special and well-known type of contour bunds is terracing contour bunds, often used for the production of rice. In comparison to normal contour bunds, terraces even out the slope of the ground and therefore make the paddies plain. Rice cultures are the best known example of contour bunds.

Contour ploughing. Terrace farming shifts the slope’s structure to create flat areas that provide water catchment. Contour ploughing suits the slope’s natural shape without changing it. On the steep slopes, wide flat steps or terraces are designed so that flat surfaces are usable for cultivation, thus minimizing surface run-off and soil erosion. Ploughing parallel to the contours …
