4.2.8 Embankment Dam Analysis-phreatic line and seepage analysis
An earthen dam made of homogenous material has the following data: Coefficient of permeability of dam material = 5.1×10⁻⁴ cm/sec; top level of dam = 290 masl; bed level of river = 235 masl; reservoir water level = 285 masl; top width of dam = 5 m; U/S slope of dam = 3:1; D/S slope of dam = 2:1. Determine the Phreatic line for the dam section and discharge passing through the dam. [8]
