ABSTRACT
The free-surface flow problem has an unknown border of the field of calculation, where we have to write boundary conditions. For this reason, it is sometimes difficult to solve this kind of determination. That is why researchers have limited their investigations to particular shapes of obstacles. In this study, we do not use a specific shape of the obstacle. Each part of the solution is analyzed. We found cases where the free-surface was not continuous and we show how we force the continuity to solve this problem.
