In recent years, affected by global warming, overturning is suppressed in large lakes such as Lake Biwa and the similar phenomenon is likely to occur in the future. In order to prevent such phenomenon, it is very important to reproduce the stratified lakes with high accuracy. However, the past research based on the hydrostatic pressure approximation did not take the loss of potential energy (𝐸𝑝) into consideration, and the analysis of 𝐸𝑝 is larger than reality. Therefore, this study is focused on internal solitary waves and tries to model the energy loss under hydrostatic pressure approximation. As a result, the energy loss of internal solitary waves can be modelled under hydrostatic pressure approximation successfully by using frictiontype energy loss and highly accurate analysis of the stratified lakes under hydrostatic conditions becomes possible.
