It is required to deepen a lake to 1.5 m over an area of 25 m x 25 m. There is water to a depth of 0.70 m in the lake The unit weight of the soil at the bottom of the lake is 14 kN/m3, and the specific gravity of the soil grains is 222 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 12 kN/m3. What would be the height of the compacted fill, when the soil is placed over an area of 40 m x 40 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)
