It is required to deepen a lake to 275m over an area of 30 m x 40 m. There is water to a depth of 10m in the lake. The unit weight of the soil at the bottom of the lake is 16 kN/m3, and the specific gravity of the soil grains is 2.57. What is the in situ water content of the soil at the bottom of the lake? It is proposed to lower the water table to the ground level and carry out the required excavation. The soil removed will be air dried and placed as compacted fill in a nearby earthwork, at dry unit weight of 14 kN/m3. What would be the height of the compacted fill, when the soil is placed over an area of 30 mx 60 m? 1 INPUT THE VALUE OF IN-SITU WATER CONTENT OF THE SOIL AT THE BOTTOM OF THE LAKE (IN PERCENTAGE FORM AND IN 2 DECIMAL PLACES) 2 INPUT THE VALUE OF THE HEIGHT OF COMPACTED FILL (IN mm AND IN 2 DECIMAL PLACES)
