The hydrostatic load is assumed to affect each element uniformly spread. This load is equal to the product of
- the hydrostatic pressure at centre of gravity of the element for a water level of 693 m.a.s.l., and
- the projection area of the element on the water-side surface of the dam wall (due to the curvature of the dam, the surface which is impacted by the water load is larger than that of the element mesh).
Due to the slopes of the centre surface between elevations of 610,37 and 678,69 m.a.s.l. (Ap-pendix Image 2) the resulting hydrostatic forces were split into two; one parallel and the other normal to the concerned element surface. cm2
