Surely you mean underwater?

Well it could be funny. lat year a road collapsed and swallowed a few cars at olympic. One reason suggested was that the deep foundations put in for the Much needed apartment blocks was diverting underground water flow and condensing it intpo rivers which washed away the underpinning of the road. basically bu the time they have completed filled the water table with 100 metre deep concret piles where is the water going to go?

It was pretty obvious what happened, they dug out a big pit right next to the road without reinforcing it. Strong rain/floods washed out the underlying material, and the road collapsed.

i am not a drainage engineer

but the way it was explained was that in rain season the water soaks in between one and 2 meters and flows downhill. it it hits a big lump of concrete all the water has to be diverted along the concrete until it hits the corner and then it flows round the cornerand carries on going down hilll. So if the foundation is 10 metres wide, then 10 metres worth of water comes together at the corner creating a stronger, more erosive current
