Rural roads now have a flood damage function model: A case study in Bangladesh of the Teesta River basin

There has been research conducted on how flooding affects road transportation conditions but there has been limited research focused on road characteristics and the direct damage of floods on roads. Therefore, field studies were undertaken to fill in the missing gaps which were conducted in rural Bangladesh's Teesta River Basin. The method of the study was questionnaire based to gather information on flood characteristics such as a qualitative measure on flood velocity and flood depth. The methods of the study were done in two ways: road types in rural Bangladesh and questionnaire survey and a development of flood damage function. This study gathered a complete database through questionnaire surveys of flood-related road damage. Further, the study mentions that “this kind of database has not previously existed in underdeveloped nations such as Bangladesh, in part because it is challenging to undertake a qualitative assessment of flood velocity through a question-and-answer session with local responders.” The purpose of the study is to “act as a valuable support in flood disaster risk management works in Bangladesh.”
