Draining Lago di Garazas, the giant puddle that I had to wade through every time I wanted to fetch something from the garbarn.

Next to the barn was a mysterious old hole with some pipes in it which looked like part of an old drainage system. Good opportunity to test that. I pumped the entire giant puddle into that and it disappeared into a downhill pipe that emptied instantly.

Nice, because the yard could do with some drainage, as you can see.

A drainage problem at the new football field site

They spent a few months moving dirt and setting up drainage for the site, and it seems like there are a few problems from the rain storm that passed through this morning.

Flow Through Granular Beds

We often rely on water draining through beds of grains, whether it’s the soil foundation beneath a building or the sand-and-gravel-filter used in water treatment. But how does water move through these tortuous porous passages? That’s what we see in this video, which places grains in a jig resembling an ant farm and lets us watch as water–and air–drain through the grains. The result is more complicated than you might imagine, with dry pockets, weak spots, and developing sinkholes. (Video and image credit: J. Choi et al.)
