Extracted text: A dam is to be constructed to supply irrigation to farms. As a low dam its height is limited to 3m and the freeboard is set to 0.5m. Design the trapezoidal dam to be as safe under all conditions. Coefficient of Friction is 0.5 and the soil bearing capacity is 125kPa. Show all the needed calculations that will lead you to conclude that your design is safe
