Deployable flexible flood mitigation device

A method for the creation of a Deployable Flexible Flood Mitigation Device manufactured from textile and membrane materials. The Flexible Flood Mitigation Device comprises a textile/membrane panel configured to be movable between an opened position and a closed position, wherein in the closed position, the panel forms a barrier against flood water; and a spool that is manually or electrically operated Is used to move the panel from the dosed position to the opened position. The spool can also be eliminated and the panel can be manually folded for storage, The Flexible Flood Mitigation Device can be configured for use in many applications including subway tunnels, vehicular tunnels, stairwells, ventilation shafts, and other openings that can be threatened by flooding, ft can be used in any orientation 9vertical, horizontal or at an angle with respect to gravity) and can stop fluids approaching from either side. 种用于创造由纺织品和膜材料制造的可展开的柔性洪水缓解装置的方法。所述柔性洪水缓解装置包括被配置用于可在打开位置和闭合位置之间移动的纺织品/膜板件，其中在所述闭合位置，所述板件形成了针对洪水的屏障；以及
