Oběh vody: The Water Cycle
Co to je oběh vody?
Co to je oběh vody? Mohl bych si jednoduše odpovědět – je všude kolem mne ! Oběh vody znamená přítomnost a pohyb vody na Zemi, v Zemi i nad Zemí. Voda je stále v pohybu a neustále mění svoji formu, z kapalné do plynné či pevné, a naopak. Oběh vody existuje již po miliardy let a veškerý pozemský život je na něm závislý; Země by bez...
Wood River Valley residents rely on groundwater for domestic supply, either from domestic or municipal-supply wells. The rapid population growth since the 1970s has caused concern about the long-term sustainability of the groundwater resource.
Nutrient enrichment can affect the ecological health of a stream. For example, excessive aquatic plant growth caused by increased nutrients can reduce dissolved oxygen necessary for other aquatic life. Topics of particular interest in this study area include:
seasonal patterns among nutrients, flows, algae and plants in streams
rooted aquatic plant vs. algae growth
In August 2013, the Beaver Creek wildfire burned more than 100,000 acres of public and private land northwest of Hailey, Idaho. According to the U.S. Forest Service, about 57 percent of the area is considered moderately burned, and the risk of post-fire soil erosion is high on more than 8,400 acres.
Because fluvial sediment poses both economic and ecological problems, resource managers need a safe, cost-effective way to measure sediment in streams, particularly in remote areas.

The Colorado River system provides about 35 million Americans with a portion of their water supply. It irrigates 5½ million acres of land in the West and provides water to tribes, parks, and wildlife. The system serves parts of seven States and Mexico—but reservoir levels have crept lower over the past several years, sparking questions about how much water remains and who will have access.
The water in the Delta arrives primarily from the Sacramento and San Joaquin Rivers, supplying water for more than 22 million people. This water source supports California’s trillion-dollar economy—the sixth largest in the world—and its $27 billion agricultural industry.
Groundwater, which flows out of sight through aquifers beneath our feet, is one of the Nation’s most important natural resources. In recognition of National Groundwater Awareness Week, March 5–11, 2017, here’s an opportunity to put your knowledge of this vital resource to the test!
