A dropdown flood barrier (100) is disclosed, which comprises at least one panel (102) and an associated counterweight (104), the panel configured to be movable between an elevated position and a lowered position in cooperation with the counterweight; and at least one rotatable drive (106) coupled to the panel, and is configured such that rotation of the rotatable drive enables the panel to be moved from the elevated position to the lowered position, the rotatable drive includes a brake arranged to exert a force against the rotation of the rotatable drive when a speed of the rotation exceeds a predetermined threshold, wherein in use, the rotatable drive is activated to enable the panel to controllably move under its own weight from the elevated position to the lowered position to form a barrier against flood water, the controllable movement of the panel enabled by the brake of the rotatable drive and the counterweight.
