Development of a Web GIS tsunami inundation mapping service

Ayça, Aykut
Tsunamis, as the catastrophic disasters, can cause loss of live and property when they come to the shores. Preparation of emergency plans is essential to reduce the damage. Consequently, any initiative in tsunami modeling and inundation mapping is of vital importance for progressing safety surveillance and maintenance. In an effort to achieve a thorough analysis of effect of tsunami, it is critical to estimate the geographical extent of possibly affected area and to predict tsunami impacts. The inundation mapping system also must serve to manage the simulation data in a scalable environment to reach end-users in the time of event. For this purpose, in this study, the generation of a Web based Geographic Information System (GIS) to serve inundation maps through web. The research methodology consists of four main stages: (i) simulating tsunamis based on six different scenarios (ii) processing simulation data through a GIS application; (iii) development of web interfaces and implementation of the developed model for Web-GIS application; (iv) verification of the created model for Marmara Sea Region. The proposed system is expected to be an efficient tool for improving inundation mapping efforts for expected tsunamis in Turkey.


Advanced two- and three-dimensional tsunami models: benchmarking and validation
Velioğlu, Deniz; Yalçıner, Ahmet Cevdet; Department of Civil Engineering (2017)
Field observations provide valuable data regarding the nearshore tsunami impact, yet only in inundation areas where tsunami waves have already flooded. Therefore, tsunami modeling is essential in order to understand tsunami behavior and prepare for tsunami inundation. Analytical and numerical methods are widely applied to predict tsunami motion and inundation characteristics. On the other hand, the data obtained from field surveys and laboratory experiments are generally used for validation and performance ...
Assessment of inland tsunami parameters and their effects on morphology /
Pamuk, Aykut; Yalçıner, Ahmet Cevdet; Department of Civil Engineering (2014)
Recent tsunami events clearly showed the potential of massive destruction on buildings, infrastructure, coastal protection structures and also morphological changes by tsunami waves. This thesis covers investigation of tsunami motion at inundation zone considering different factors (smoothed ground without buildings, or with buildings), and related changes of inland tsunami parameters and their effects on morphology. For the applications, the simulations have been performed using different topographic condi...
Assessment of tsunami resilience of ports by high resolution numerical modeling: a case study for Haydarpasa port in the sea of Marmara
Aytöre, Betül; Yalçıner, Ahmet Cevdet; Department of Civil Engineering (2015)
Assessment of tsunami resilience is used to determine proper mitigation strategies. Thus, it is essential to obtain modeling results in highest confidence and accuracy. Haydarpasa Port in the Sea of Marmara is selected for tsunami assessment study due to vulnerable nature of ports against marine related disasters. The region also tends to have tsunamis since it is located on the western part of the North Anatolian Fault zone where 35 tsunamis occurred in last 2000 years. The aim of this study is assessment ...
Database development for tsunami information system /
Özdemir, Koray Kaan; Yalçıner, Ahmet Cevdet; Department of Civil Engineering (2014)
Tsunamis are believed to be one of the natural enemies of human kind and evolution as the damage it gives at the shores can be described as lethal in means of loss of lives, tangible damage to the economy and concrete living on the shore, threat to health in variety of sicknesses after drawdown of water. Since this phenomena has been lethal lately even in a country like Japan which was prepared for any fatal earthquakes and tsunamis, it is in great importance to use the technology and history in accordance ...
Geochemical traces of historical Eastern Mediterranean tsunamis in the sediments of Öüdeniz lagoon, sw Turkey.
Yeniçeri, Murat Toygar; Avşar, Ulaş; Department of Geological Engineering (2020)
Tsunami is flooding of huge wave of sea water over the land that has the potential to cause destruction and devastation on the coastal regions. They are the result of large subaqueous mass movements possibly related to earthquakes, landslides and volcanic eruptions. More than 44 tsunamis having intensities higher than 6 have been recorded historically in the Mediterranean and connected seas. In order to reveal their sedimentological traces, we investigated Ölüdeniz Lagoon, a depositional environment which h...
