Abstract
Techniques to analyze the bottom topography in a closed water area are described. Positioning data are recorded with a global positioning system, and depth data are recorded with an echo sounder. Positioning data and depth data are synchronized to generate three-dimensional topographical data. Errors due to ship's movement are corrected using outputs from a clinometer and a compass. The change due to sedimentation is investigated for the bottom topography of Kojima Lake. We describe numerical techniques based on a finite-element method and an explicit time integration method to analyze flow generated in Kojima Lake.
