Abstract:
In the context of Tsunamis the location of Galle is extremely vulnerable. It lies besides a
wide bay and a natural headland on which is located the historic Galle Fort with very
reflective vertical non-porous walls on all sides. In the vicinity of the headland on which
the Galle Fort is located, the wave energy concentrates due to refraction. These waves then
reflected from the vertical solid walls of the Fort and moved around the headland. Such
walls reflect almost all the incident wave energy with very high wave heights at the wall
itself. There is hardly any dissipation.
