Flood the Gaza Tunnels | RealClearWire
The geography of Gaza argues strongly for the stratagem of flooding the tunnels. It would force the enemy above ground where they can more easily be destroyed, dramatically reduce the Israeli casualties required to accomplish that task and resolve the problem of dealing with parts of the tunnels that are too deep to destroy through bombing. Most importantly, flooding is a permanent or near-permanent solution to the Gaza tunnel problem. Once accomplished, pumping them out enough to be usable again would be both extremely costly and especially in conjunction with bombing exceptionally difficult. The timing of executing a flooding strategy is flexible; some could be flooded now, others later, and still others once they re discovered.
The engineering is straightforward. Egypt flooded thirty-seven cross-border tunnels in southern Gaza back in 2015 in what stands as a practical proof of concept in this location. Seawater from the Mediterranean would be pumped directly into the tunnel openings through short pipelines. While there s little hydrological head, there is also little topographical relief to deal with in laying the pipe. Large volumes of water are pumped long distances every day, and Israeli water technology is world class.
Sounds like a plan.
