INFLUENCE OF THE GEOMETRICAL SHAPE OF AGRICULTURAL FURROW (GROOVES) ON THE SEDIMENT TRANSPORT

摘要

In this experimental work, it is shown that the geometric shape of the farming grooves could play an important role in sediment dynamics. From these results, it appears that, for slopes less than 40%, the grooves with a sinus shape export the least sediment mass. For steeper slopes, agricultural furrows in a circle lead to the minimum of sediment transport. The rheological behaviour of the solid discharge depends also strongly on the geometry of the grooves.
