Large rivers sourced in the Rocky Mountains cut through elevated plains that exhibit limited river drainage but widespread surface water in the form of ephemeral (seasonal) playa lakes1, as well as extensive groundwater hosted in the High Plains aquifer of the Ogallala formations2. Here we ...
various topographic maps with a scale of 1:250,000 and multisentinel1 radar data (Table1) were used and analyzed. Furthermore, in addition to the Google Earth Platform (GEE), ArcMap 10.6.1 and Snap 9.0.0 were used to preprocess, process, and postprocess the topographic maps and satellite...
They receive most of their water from precipitation and surface runoff and lose water through aquifer recharge and evaporation [61]. They are usually dry during late winter, early spring, and late summer and may experience multiple wet-dry cycles during a single year. Because of the highly ...
but it sits atop the Ogallala Aquifer, which stretches into eight states. High winds virtually strip the vines of pests and disease. This desolate region is more of a growing area than a winemaking one, although it contains at least six wineries. All the conditions here are right for this...
The work presented here provides the first intensive insight into the bacterial populations in the digestive tract of the North American moose (Alces alces). Eight free-range moose on natural pasture were sampled, producing eight rumen samples and six co

The principal causes are aquifer-system compaction, hydro-compaction, natural compaction, underground mining, drainage of organic soils, sinkholes, and thawing permafrost [15]. Nearly the entire East Coast of the United States, from Massachusetts and parts of Maine to Florida, is known to be ...
