Soil texture plays a big major role in groundwater recharge, storage discharge as well as vulnerability to contamination. This project focuses on investigating the changes in soil texture at the watershed level, in efforts to analyse and predict water flow pathways through the soil.
Soil texture influences the rate of water infiltration through the soil. The soil hydraulic conductivity, permeability and water holding capacity changes along the watershed. In the previous map, areas with a course textured soil such as sandy and sandy loam, are expected to have a higher capacity to water infiltration. On the other hand, fine textures, such as clay and silt soils, limits infiltration of rainwater, leading to an increased runoff.
