Two sheet piles were driven 4 m apart into clayey sand, as shown in Figure 8.9, and a 2 m depth of soil between the two sheet piles was removed. To facilitate some proposed construction work, the region between the sheet piles is being dewatered where the water level is lowered to the excavation level by pumping out water con- tinuously. Assuming the hydraulic conductivity of the clayey sand as 2 x 10-6 cm/s, estimate the quantity of water that has to be pumped out per meter length per day. 4.0 m 2.5 m 2.0 m * 3.0 m K Sheet pile Impervious stratum Ground Level Clayey sand

![EXAMPLE 8.4
Two sheet piles were driven 4 m apart into clayey sand, as shown in Figure 8.9, and
a 2 m depth of soil between the two sheet piles was removed. To facilitate some
proposed construction work, the region between the sheet piles is being dewatered
where the water level is lowered to the excavation level by pumping out water con-
tinuously. Assuming the hydraulic conductivity of the clayey sand as 2 x 10-6 cm/s,
estimate the quantity of water that has to be pumped out per meter length per day.
