Abstract. The Papathoma Tsunami Vulnerability Assessment (PTVA) Model (Papathoma, 2003) was developed in the absence of robust, well-constructed and validated building fragility models for assessing the vulnerability of buildings to tsunami. It has proven to be a useful tool for providing assessments of building vulnerability. We present an enhanced version (PTVA-3) of the model that takes account of new understanding of the factors that influence building vulnerability and significantly, introduce the use of the Analytic Hierarchy Process (AHP) for weighting the various attributes in order to limit concerns about subjective ranking of attributes in the original model. We successfully test PTVA-3 using building data from Maroubra, Sydney, Australia.

<p>The Kedukan Bukit inscription was written in 682 AD. It is considered as the oldest inscription related to the kingdom of Srivijaya and an authentic proof of the advanced maritime culture of Srivijaya. This argument is supported by the fact that, geographically, Sumatra is endowed with hundreds of large and small rivers that have generated abundant natural resources from its upstream to downstream areas. Srivijaya must have utilized these natural conditions to facilitate the distribution of its trade commodities—pepper, camphor, resin, and gold—from the upstream regions (flowing through countless tributaries to the main rivers) to the coastal areas, and even further to the various ports in Southeast Asia. Archaeological methods were used to identify and analyze a number of findings in the form of ancient boat artifacts from Srvijaya period in terms of both their respective forms and positions as they were unearthed along the Batanghari and Musi watersheds, from the upstream to estuary areas. From these findings, it can be inferred that Srivijaya managed to build a pattern of distribution network of trade commodities and to develop a sophisticated boat technology to support it. The commodity distribution network started from the upstream areas, namely the feeder points, all the way down to the downstream areas, namely the collecting centers; then, the commodities would be transported to the estuary, namely the main port of Srivijaya, and then carried to various other ports throughout Southeast Asia. The development of boat technology is the second key to the success and effectiveness of the pattern of trade commodity distribution that Srivijaya created from its upstream to downstream areas. The combination of such distribution network pattern and the development of boat technology has successfully established Srivijaya’s image as the most influential maritime power in Southeast Asia in the ancient period.</p>

Current Energy

Korea is a very well-known country for having abundant tidal current energy resources. There are many attractive coastal areas for the tidal current power that have very strong currents due to the high tidal range and the acceleration through the narrow channels between islands in the west and south coasts of the Korean peninsula. Recently, the Korean government announced a plan that aims to increase the portion of electricity generated from renewable energy to 20% by 2030. Korea has abundant tidal current energy resources; however, as reliable resource assessment results of tidal current energy are not sufficient, the portion of tidal current power is very small in the plan. Therefore, a reliable resource assessment should be conducted in order to provide a basis for the development plan. This paper describes the resource assessment of tidal current energy in Korea based on the observational data provided by KHOA (Korean Hydrographic and Oceanographic Agency) and numerical simulation of water circulation. As the observational data were unable to present the detailed distribution of the complicated tidal current between islands, numerical simulation of water circulation was used to describe the detailed distribution of tidal current in Incheon-Gyeonggi and Jeollanam-do, where the tidal energy potentials are abundant. The west and south coastal areas of Korea were divided into seven regions according to the administrative district, and the theoretical tidal current potential was calculated using average power intercepted. The results of this research can provide the insight of the tidal current energy development plan in Korea.

Bridge Abutment

Tsunamis can seriously damage bridges in coastal areas. Studies of such damage have elucidated the action of tsunami-induced forces on girders. However, tsunami-induced erosion of bridge-abutment backfill has been largely neglected. This article investigates this little-studied topic using hydraulic model experiments and numerical analyses. The results show that a tsunami erodes the backfill close to the abutment; the scale of the erosion increases with the duration of the tsunami. By contrast, the backfill on the far side of the abutment remains relatively intact. This suggests that the presence of the abutment accelerates the erosion of the backfill in its vicinity. A numerical simulation shows that the tsunami erodes the oval conical part of the backfill on the landward side of the onshore wing. When the erosion reaches the lower end of the wing the backfill begins to flow out from underneath. Thus, an increase in the soil-cover depth of the onshore wing might help slow down the erosion.

More and more people have take more attention on the problem like Seawater intrusion, The same floor recharge and "heat transfixion". This article has established the groundwater flow and solute transport and temperature coupling numerical model,to simulate the underground water temperature’s change by changing the wells’ spacing manner. Simulation results show that the two kinds of disposing Wells solutions are not cause seawater invasion, the second disposing Wells scheme help to prevent the occurrence of seawater invasion.
