Here, () is the equation air/water interface, is the incremental displacement of the interface, and is the surface tension of water. For a given value of ρ s {\displaystyle \rho _{s}} , stable equilibrium configurations are identified as being those values of h {\displaystyle h} and α {\displaystyle \alpha } that satisfy
