Flooding may occur as an overflow of water from water bodies, such as a river or lake, in which the water overtops or breaks levees, resulting in some of that water escaping its usual boundaries, or it may occur due to an accumulation of rainwater on saturated ground in an areal flood.

Often, two technologies emerge more or less simultaneously, and then reinforce each other as mutually compatible technologies. In doing so, they can create a kind of synergy together and make one another more efficient, more cost-effective, more profitable, and more useful—like a pair of horses working together to pull a

There are few more compelling images of the American adventure than those of the Old West. Whether depicted in fiction, photos, film, or ballads, they celebrate the heyday when gold, copper, and silver were king.

Editor’s Comments: The Desiccated Future

About a year and a half ago, in the January/February 2017 issue of the magazine, I mentioned predictions from NASA and other organizations that the US is in for a megadrought sometime during this century. A megadrought is one that lasts for decades rather than months or years, and we

Battling Invasive Species

When William Shakespeare introduced the starling into his play Henry IV more than 400 years ago, he recognized the bird’s moderately annoying qualities by imagining it tormenting its host with the repetition of a single utterance—over and over and over. However, he certainly could have had no concept that his
