This zone is generally 1 m or less above the water table, which is defined as the top of the region where virtually all the pore space is filled with groundwater. Which soil has the highest capillary action?
WebThe more fine-grained the sediment or rock, the higher the water is pulled. The diameter of the pore opening and the degree of connection with the saturated zone is very important. So much water is drawn into the pores above the water table that this zone is given a special term, the capillary fringe. Permeability of rocks WebMar 23, 2024 · The subgrade fill belongs to the unsaturated soil. The hydrogeological zone of the subgrade soil affected by groundwater is generally divided into four parts: residual water-bearing zone (bound, pore capillary, and partial suspension capillary water), capillary fringe, capillary saturated zone, and saturation zone (below the phreatic …
