Tracking Water Flows by Temperature
Using a thermal imaging camera, engineers at University of Nebraska-Lincoln can visualize patches of warm water, such as discharge from power plants, as well as the flows of water on a large scale using aerial photography.
The Colorado River is one of the most stressed rivers in the U.S., and about 80 percent of its water comes from snowmelt. Research shows that dark-colored dust out of the Southwest now makes melt come earlier in the year--ultimately causing the river to lose more of its precious water annually.
Students Build Water Systems
The student organization Global Water Brigades is devoted to helping developing countries that lack basic water sanitation. At Northwestern University, students have been working with a village in Honduras to build pilas, a traditional water storage unit used by many Honduran families, and to provide water quality education.
