New Technology: Stop Flooding Under Levees

What flooding problem is being addressed with the new tech? seepage under a levee known as sand boil

How does the tech work?

• an umbrella-shaped screening device is inserted into the land
• to prevent sand boils from growing
• relieves underground hydrostatic pressure that created the sand boil
• inhibits subterranean erosion that can cause [the] failure of a nearby levee

What will this replace? sandbags around levees

Tech Link | 23 states listed in NOAA flood warning. Could this umbrella-like invention protect their levees?
