Probable flood depth - we have a range of flood barriers for MFDs from 25cm to 80cm (MFD = Max Flood Depth). Smaller AquaDams are easier to install, cost less and require less space but will retain less flood depth.
Notice of flooding - flooding associated with tidal surge is a predictable flood threat. Periods of elevated threat can be determined years in advance from tide tables - this is a typical AquaDam flood protection scenario. The other extreme is flash flooding resulting from rainfall associated with severe, multi cell, thunderstorms. AquaDam is rarely a suitable for flash floods.
Water supply - typically AquaDams are filled with water from a pond, a river or stream, the sea or a fire hydrant.
Manpower - depending upon AquaDam size and total length a flood barrier will require a minimum manpower to install. There are any number of possible permutations but a hypothetical example - an hotel with 4 physically fit staff led by an AquaDam trained hotel manager could comfortably install a 50m / 50cm MFD flood barrier in half a day.
Space for deployment - water filled cofferdams are typically twice as wide as they are tall.
The triple photo sequence below is part of a 6 x 25m TEXAS model AquaDam (total barrier length 150m). The TEXAS has a 190cm filled width. Installation team 4 physically fit individuals. Water will be drawn from flood water. The 6 dams and petol water pumps and equipment are stored in a single garage.
