A study on proposal of the floating disaster prevention house against flood disasters (part 1) : Consideration of floating performance of the floating unit by water tank experiment

Abstract

The floating disaster prevention house (FDPH) was proposed, and conclusions about its disaster prevention performance were obtained as follows from this study. ,,1. The floating unit can perform the floating performance regardless of the slit position and the slit area of the flood wall, flow velocity and elevating speed of the water level.,, 2. The floating behavior of the floating unit can be reduced at the start of floating by setting up the clearance between the bottom of the flood wall and the floating unit. ,,3. FDPH is expected to be less susceptible to fluid pressure and drifting objects.
