Basic Concepts of Water Resource Sustainability

The majority of the earth's surface is composed of water. The water which is available for use by the living beings on earth comes from various water resources. Water resources are the naturally occurring water bodies that are intended to be used by the living beings on earth for drinking and other uses. Water resources provide 3% as freshwater, 97% as saltwater, two-thirds of which are frozen as glaciers and ices. The remaining water which generally doesn't remain frozen are the water resources found underground, precisely known as groundwater. The majority of these water sources act as non-convention sources of power generation, like in hydropower stations.

Assume that an area is underlain by a stratum of compressible soil 5.3 m thick. The weight of the proposed structure, say an earth embankment for a new highway, will result in an increase of 28.2 kPa pressure to the compressible soil. The settlement under this loading would be 0.30 m. The 385 compressible layer is doubly drained, and the soil has a cv value of 0.4 m2/month. Calculations indicate that it would take approximately 22 months for the settlement to occur under the weight of the proposed embankment. How long would be required for a surcharge imposing a pressure of 56.4 kPa to cause the 0.30 m of settlement?
