Geotechnical Curiosity

[IRstuff]

So, this lot was all nicely graded and compacted for construction a few months back and after one of the previous storms, there were a bunch of material loss, but I couldn't quite come up with a plausible explanation for the "holes" on the side. When I look at the top of the mound, I don't see any obvious holes on the top, so water doesn't appear to have flowed from inside the mound.

Any ideas?

I was on a site where the material would self compact when wet.
It was a clay based silt.
When the crew turned a (fire) hose on some un-compacted soil, you could see the surface subsiding.
What really surprised me was the time a truck became stuck in dry soil.
The crew tuned on the hose, and when the soil was well wetted, the driver got in the truck and drove away.

I guess it makes sense that the slopes of the mound aren't as compacted and might get easily undermined and washed away. I guess I was sort of expecting more erosion or much less erosion.
