The gate-like mechanism works much like an ordinary stable door, except substituting floodwater for the horse, with the door effectively 'blocking' the floodwater, or horse - ensuring of course that the gate is secured in the 'closed' position.
The structure, which took a team of engineers over 4 hours to design and build, is to be lowered into place in the West Country where the flooding is at its most severe. Any water which has already passed this point can simply be coaxed back behind the gate's defenses.
"We believe the time is right for this giant fortification to be put into position", said a spokesperson for the Department of the Environment. "With this technology we can really nip this flooding issue in the bud."
"Obviously, no plan can be completely full-proof, but we believe with the correct application, the measure has every chance of success, with only a slim chance that the moment has evaded us and galloped into the distance with mare-like enthusiasm."
