The topographic parameters normally considered
for estimating soil erosion losses that includes inclination and length of
slope. Scientists have experiment the solution and it results that the
laboratory tests and field observations are used to determine the effect ofslope shape on both mass stability and resistance towards rainfall erosion. Thus,
it is concluded that the concave and compound slope shapes are superior to
planar forms in terms of improving mass stability and limiting erosion.
Why do most
natural slopes have curvilinear rather than planar profiles? What slope shape
is best suited for minimizing erosion losses …. convex, concave, compound
(convex-concave), or planar (uniform)? Why are most man-made slopes constructed
with planar surfaces and uniform gradients? These are not trivial questions -
perhaps no other variable affects the stability of slopes with regard to both
surficial erosion and mass wasting as does topography or slope morphology.
Topographic parameters normally considered in estimating soil erosion lossesinclude inclination and length of slope. Surprisingly, slope shape is seldom if
ever considered. Conceptual and mathematical models, as well as the results of
laboratory tests and field observations, can be used to determine the effect of
slope shape on both mass stability and resistance to rainfall erosion.
