@article{(Open Science Index):https://publications.waset.org/pdf/12179, title = {Developing Damage Assessment Model for Bridge Surroundings: A Study of Disaster by Typhoon Morakot in Taiwan}, author = {Jieh-Haur Chen and Pei-Fen Huang}, country = {}, institution = {}, abstract = {This paper presents an integrated model that automatically measures the change of rivers, damage area of bridge surroundings, and change of vegetation. The proposed model is on the basis of a neurofuzzy mechanism enhanced by SOM optimization algorithm, and also includes three functions to deal with river imagery. High resolution imagery from FORMOSAT-2 satellite taken before and after the invasion period is adopted. By randomly selecting a bridge out of 129 destroyed bridges, the recognition results show that the average width has increased 66%. The ruined segment of the bridge is located exactly at the most scour region. The vegetation coverage has also reduced to nearly 90% of the original. The results yielded from the proposed model demonstrate a pinpoint accuracy rate at 99.94%. This study brings up a successful tool not only for large-scale damage assessment but for precise measurement to disasters.}, journal = {International Journal of Civil and Environmental Engineering}, volume = {6}, number = {2}, year = {2012}, pages = {114 - 119}, ee = {https://publications.waset.org/pdf/12179}, url = {https://publications.waset.org/vol/62}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 62, 2012}, }
