WebBoussinesq (1842 – 1929) evolved equations that can be used to determine stresses at any point P at a depth z as a result of a surface point load. Vertical pressure within an earth mass Boussinesq's Formula … WebThe Boussinesq Approximation is suitable when variations in density are due to thermal rather than pressure changes, thus the approximation is clearly justified for water. The Boussinesq approximation is also valid for a compressible gas, such as air, if the vertical extent of the flow, d, is much smaller than the density scale height, i.e.
