The figure shows a 50-m-long concrete dam that rests on silty clay. The water level on the left hand side of the dam is $6\mathrm{m}$ higher than the water level on the right hand side. Due to the difference in water levels on the two sides, there is seepage occurring underneath the dam. A flow net has been already drawn to analyze this seepage situation. Answer the following questions based on the information available on this figure. a) Write down the values of the following parameters: b) If it is given that the hydraulic conductivity of the silty clay is $2.5\times 10^{?3}\mathrm{m}/$ day, and the width of dam perpendicular to the cross-section $=120\mathrm{m}$, calculate the seepage loss $Q$. c) What is the pressure head (not counting seepage loss) at Point P? $h_p=$ m d) What is the seepage loss head at Point P? $h_{\text{seep }}=$ e) What is the pressure acting on the base of the dam at Point $P$ ? $P_P=786?40?1\mathrm{kPa}$
