A massive, concrete dam spillway has been instrumented with a series of piezometers, A through E, to monitor pore-water pressures at various locations through the permeable soil deposit (next page). The reference datum in this case coincides with the downstream water table, and all dimensions are reported in meters (m). (A) Determine the elevation head for all piezometers A through E. (B) Determine the pressure head for all piezometers A through E. (C) Determine the total (piezometric) head for all piezometers A through E. (D) Determine the pore-water pressure (kN/m²) at all locations where piezometers A through E have been installed. (Note: unit weight of water - 9.81 kN/m².) (E) Present your results in a reasonably organized, tabulated fashion.
