Linking soil hydraulic properties with soil erosion estimations
Saturated hydraulic conductivity Ks can be used to describe water movement under saturated
conditions in the soils. It differentiates the amount of water infiltrating into the soil and the amount of
water flowing over the surface as runoff. Soils with small values of hydraulic conductivity have low
infiltration rates and during intense rains, water run-off will lead to consequent soil losses and surface
transport of colloids, nutrients, and microbes, which can then cause problems of eutrophication and
pollution of downstream areas (Dexter et al., 2004).
Objectives:
1. To locate the hotspots with low saturated hydraulic conductivity and high soil erosion
2. To combine saturated hydraulic conductivity (Gupta et al, 2021) and soil erosion (Pasquale et
al., 2017) spatial maps to modify risk classes
