A flownet is given below for flow under a concrete dam. The dam is 60 m long and has two 10 m sheet piles driven partially into the granular soil layer. The datum is at the surface of impervious bedrock, shown in the figure. The water level is H=20 m above soil layer in the upper stream and at the soil layer surface in downstream. The coefficient of permeability of soil is k= 0.6 m/day. Calculate the quantity of seepage under the dam during a period of 10 days. Unit: m3

Highway Surveys and Location

Surveying is an operation in the civil engineering domain that requires collecting and identifying data regarding an area of land and topography. The data that is collected can be helped to plan and undertake the construction process. Civil engineers perform surveys to gather three-dimensional information regarding a particular area. Engineers specify several points on the surface of the earth and relationship between points, and the distance and angles between the points are evaluated. The data from this evaluation guides in drawing plans regarding buildings and structures.
