how sand bags help prevent flooding, yet sand is also used for drainage since it’s porous and water easily flows through it?
In: Engineering
there are multiple kinds of sand; some sand works better than others; especially when wet.
sand bags are very malliable which makes them great for stacking around corners and bumps and curved areas
sandbags are NOT water tight and arent designed to be; since water will take the path of least resistance the sandbags help “guide” the water away from where we dont want it to go
