[7 marks]Enlist various causes of failure of an earth dam.
[3 marks]What is rolled fill earth dam and hydraulic fill earth dam?
[4 marks]Describe with neat sketch how seepage line is drawn in homogeneous earth dam without any drainage arrangement?
[7 marks]Discuss measures to control seepage through earth dam and their foundation.
[7 marks]In order to compute the seepage discharge, a flow net is plotted for a homogeneous earth dam of height of 30 m and free board 2.0 m. The results obtained were: Number of potential drops = Number of flow channels = The dam has a horizontal filter of 30 m length at the downstream end. Compute the seepage discharge per meter length of the dam if the coefficient of permeability of dam material is 3 × 10-4 cm/s.
