Post earthquake bridge damage assessment coupling field data and reliability tool

Abstract. To date, in Austria no empirical assessment of absolute damage curves has been realized on the basis of detailed information on flooded buildings due to a dam breach, presumably because of the lack of data. This paper tries to fill this gap by estimating an absolute flood-damage curve, based on data of a recent flood event in Austria in 2006. First, a concise analysis of the case study area is conducted, i.e., the maximum damage potential is identified by using raster-based GIS. Thereafter, previous literature findings on existing flood-damage functions are considered in order to determine a volume-water damage function that can be used for further flood damage assessment. Finally, the flood damage function is cross validated and applied in prediction of damage potential in the study area. For future development of the estimated flood damage curve, and to aid more general use, we propose verification against field data on damage caused by natural waves in rivers.

Careful Assessment

Disasters cause destruction, but also bring opportunities for development. A lack of this perspective in disaster management leads to planning and managerial follies. The reconstruction and rehabilitation program from the Latur earthquake (Maharashtra, India) should be used as a starting point. Leh, the largest district of India, was hit by a cloudburst and subsequent flashfloods on 05–07 August 2010. The monetary value of the total damages is estimated to be approximately Rs 225 crores. A total of 87% of the affected infrastructure required complete reconstruction. The rest received partial damages. This paper uses field data collected on development needs in 112 villages over a span of five years (just preceding the disaster) and data for damage assessment from the 42 affected villages collected immediately after the disaster. The paper does a careful assessment of the damages in the flashflood, analyses the pre-existing developmental requirements of all the villages in the district, and explores the possibilities of integrating post-disaster reconstruction with the pre-existing developmental requirements. In India, post-disaster reconstruction quite often is an elaboration of short-term, makeshift arrangements, thereby giving rise to obvious developmental concerns. Merits and demerits of this strategy will be discussed. This research examines the financial implications of integrating reconstruction projects with development programs. It also looks into the sustainability of development, and how can this serve as a strategy in making communities more resilient to future disasters.
