A canal is located in an area where the alignment parallels that of a nearby river. The difference in the water surface elevation of the canal and the river is 10 m. A 3-m-thick buried stratum of granular soil (permeable) extending between the canal and river is bounded by layers of clay (impermeable). The horizontal distance between the two bodies of water is 400 m. The coefficient of permeability for the granular soil is 0.75 m per day. (a) Make a sketch of the described conditions. (b) Calculate the volume of seepage that occurs from the canal to the river, per kilometer of canal length.

Calculation of Settlement

The vertical displacement of the structural foundation due to the loading from the superstructure is known as settlement. It is due to the reduction of air voids present in the soil. The amount of vertical displacement depends on the bearing capacity of the soil on which the foundation is laid. The effect of the settlement depends on the magnitude of settlement, uniformity, and the structural design of the structure. The maximum allowable settlement for residential and office buildings should be less than 18 mm, for industrial buildings, it is 38 mm and for commercial buildings, it is 25 mm.
