Structures Impacted by Tsunami Bores Research Paper

Structures Impacted by Tsunami Bores - Research Paper Example The study seeks to offer understanding into the ways by which the coastal areas can be able to prepare themselves to withstand dangerous hydrodynamic forces associated with large tsunami waves that are progressing to the mainland.The conduct of this study is based on the recent occurrences of tsunamis that have majorly hit parts of the world such as Japan, Philippines, and Chile. As a result, many human lives have been endangered out of the tsunami waves that have extended into the mainland, hence causing severe destruction of buildings. The economic loss attributed to these tsunami attacks are also enormous with the 2011 attack costing US$319 billion worth of damages. The current study aimed at showing that the design of buildings needs to be done in consideration of the hydrodynamic forces, especially in the tsunami prone areas. By developing new guidelines and recommendations, it is aimed that the same will be applied in hydrodynamic constructions. In testing for the interaction b etween the bore and the structure, it is determined that a zero level of water momentum results in an impulsive force being exerted in the upstream. Consequently, the study established that for narrow channel conditions, the run-up power can strongly be affected by the channels. These channels can be built through SPH method as shown in the figure 2 below. Therefore, the study recommends taking special care in interpreting the hydrodynamic forces following initial impacts from the bore.
