Abstract: A submerged multi-purpose facility is optimally located with respect to lateral forces and hydrostatic forces. Lateral force readings are first observed for the geographic location under consideration at a plurality of depths. From these readings, a lateral force curve is developed which is exponential in shape. The mid-range of this curve and just below the mid-range are the depths where the facility is ideally to be located. The facility can then be structured with respect to wall strength to withstand the hydrostatic forces at the depth location determined by the above technique.
