SpletThese are called the horizons of a typical soil profile. The uppermost horizon is called the “organic” horizon or “O” horizon. Just below the O horizon is “topsoil” or “A” horizon. … SpletBelow the subsoil is the C horizon, or parent material, which is what initially formed the soil. The parent material is most commonly rocks moved by glaciers, formed over large amounts of time. Finally, below the parent material, is the R horizon, or regolith. Basically, it’s just a layer of rocks- there’s really not a whole lot to it. Splet4.2.2. Constrained Deformation Modulus Moduli describing the deformability of subsoil are determined from in-situ tests with empirical relationships. The relationship between the constrained modulus of defor- mation M0 and parameters describing properties of alluvial subsoil is described by the same function which determines equation (6). rita wolba
