Summary: | <p>In view of the complexity of the phenomenon of water
related soil erosion in the Bia catchment area, linked to a large
heterogeneity of soils, to a very scattered and in some places non-existent
vegetation cover, and to a poorly distributed precipitation in both space
and time, a mapping test of the “specific erosion” random variable is
undertaken. The mapping of the intensity of the erosion hazard was carried
out using the Universal Soil Loss Model (USLE). The map shows that the basin
is generally characterized by relatively moderate erosion rates with an
average erosion rate of 16 t/ha/year.</p> |
