Tank experiment
There is a hole outside my appartment that in the future will hold a parking garage. It is a pity, because the garage is going to destroy my direct view of the sunrise over the swamp from the breakfast table.
In the meantime, I have set it up as a sedimentology lab experiment. In the heavy summer downpours here in Houston, there is actually some erosion of sand from the neighbours' flower beds. This flows down a footpath and empties into "Garage construction lake" at the base of the picture here (notice channel scour) and then builds a nice friction dominated mouthbar of rippled sand into the shallow water. The picture is unfortunately not that good, there are actually two separate lobes built at various water depths and in two separate episodes of sedimentation (aka rain showers!)
