Managing for Drought

The mania for a green lawn, or in some cases green anything, across many regions of the US has been quelled by recent droughts (thankfully now abating). Even long before water meters were spinning at record rates for golf resorts, private homes, and corporate campuses, scientists have been devising technologies

Stopping a Sinkhole to Save an Alabama Highway

With flooding, sinkholes, danger, and suspense, this story may resemble the latest Hollywood adventure film.

Solutions for the Drainage Dilemma

A quick perusal of once-popular English literature would show that the Victorians, and indeed a century of their predecessors, were eager to adopt any innovations to improve drainage. While most agrarian societies fought weather, taxes, and landlords to keep crops in the field, drainage for them and the estate managers

Dramatic photos that captured the devastation of the central plains Dust Bowl of the Great Depression are compelling evidence of how dry, vulnerable soil, transported by wind, transforms the landscape.
