The flood damage function model is indispensable for assessment as it can provide useful information establishing protection strategies. For the of residential house in different areas, models have been traditionally proposed considering only depth–damage curve. However, duration and may also an influence on damage. Conventionally, rate was estimated based about monetary losses collected from local people or insurance payout databases. This research proposes a new methodology to establish that considers depth, duration, velocity. Field surveys were conducted Teesta River Basin rural Bangladesh. each house, questionnaire identify (flood qualitative representation velocity), household structure (area, plinth height, ceiling height), structural mechanism, required amount material labor repair after event. Finally, including impacts types parameters established through multiple regression analysis. consistency verified estimation statistical parameters. It serve loss correlates flooding with various parameters, such building materials their mechanism.
