Tufa-depositing springs in the southern Driftless Area of Wisconsin, USA, are used to inform the response of shallow and local groundwater flow systems to changes in climate over the last 3,000 years. The springs emanate from a shallow, unconfined, sedimentary bedrock aquifer and at stratigraphic positions similar to a shallow, perched aquifer that was identified in the eastern Driftless Area. The perched aquifer was shown to be stable under current climate conditions and over decadal time scale...

Although springs have been recognized as important, rare, and globally threatened ecosystems, there is as yet no consistent and comprehensive classification system or common lexicon for springs. In this paper, 12 spheres of discharge of springs are defined, sketched, displayed with photographs, and described relative to their hydrogeology of occurrence, and the microhabitats and ecosystems they support. A few of the spheres of discharge have been previously recognized and used by hydrogeologists...

Thermal remote sensing is increasingly utilized as a tool in hydrology because it is easily-transferable, can provide high-resolution, synoptic views of water resource issues and may provide answers to difficult research questions. Thermal infrared radiation is generally considered to have a wavelength between 3.5-20 渭m. Commercial thermal infrared sensors typically detect radiation in the 7.5-13 渭m wavebands. The reduced cost of thermal imaging cameras now provides a cost-effective method for i...
