Tsunami damage reduction performance of a mangrove forest in Banda Aceh, Indonesia inferred from field data and a numerical model
[1] Since the 26 December 2004 Indian Ocean tsunami, the role of mangrove forests as natural defenses protecting coastal communities from tsunami disaster has been highlighted. However, some mangrove forests were destroyed by that tsunami. They are expected to have lost their protective functions. In this study, we develop a fragility function to assess the mangrove trees’ vulnerability, expres...
متن کاملCoastal mangrove forests mitigated tsunami
A study conducted after the 26th of December 2004 tsunami in 18 coastal hamlets along the south-east coast of India reiterates the importance of coastal mangrove vegetations and location characteristics of human inhabitation to protect lives and wealth from the fury of tsunami. The tsunami caused human death and loss of wealth and these decreased with the area of coastal vegetation, distance an...
متن کاملInformation Brief on Mangroves in Sri Lanka
Mangrove ecosystems played a vital role in buffering the force of the tsunami waves and in protecting the human inhabitations. Even before the Tsunami, Sri Lanka has been experiencing rapid loss of mangrove ecosystems mainly due to anthropogenic factors including unprecedented growth of the tourism sector. In addition to the provision of ecosystem functions, the mangroves are instrumental in su...
متن کاملDeveloping fragility functions for tsunami damage estimation using the numerical model and satellite imagery
Recent development of numerical modeling of tsunami and remote sensing technologies enable us to determine the detailed features of tsunami damage. Numerical model with high-accuracy and high-resolution bathymetry/topography grid predicts the local hydrodynamic features of tsunami, such as inundation depth and current velocity. Also, high-resolution satellite imagery provides detailed informati...
متن کاملHow effective were mangroves as a defence against the recent tsunami?
Whether or not mangroves function as buffers against tsunamis is the subject of in-depth research, the importance of which has been neglected or underestimated before the recent killer tsunami struck. Our preliminary post-tsunami surveys of Sri Lankan mangrove sites with different degrees of degradation indicate that human activity exacerbated the damage inflicted on the coastal zone by the tsu...
