WebNov 25, 2024 · When saturated, soils with large, continuous pores will have a much greater hydraulic conductivity compared to soils with small, discontinuous pores. As soil water content decreases, the hydraulic conductivity decreases because: (1) the total volume of water-filled pores decreases; and (2) the size of water-filled pores decreases (Figure 4.12). WebThe porosity is a measure of how the volume of voids per unit volume of the deposit. The porosity of sediments depends on the grain size, shape, roundness, sorting, and the level of compactness. The sediment porosity can vary from 0.82 for freshly deposited clays to 0.25 for extremely poorly sorted sediments.
