Techniques developed in previous studies were applied to positional data and depth data concerning underwater topography of a reservoir. The Gauss-Krüger projection was applied to horizontal coordinates of positional data. The horizontal coordinates and the vertical coordinate yielded a curve in an underwater topography. A surface containing the curve was obtained by a fixed point iteration. Numerical results for two time periods were compared.
