Universal Soil Loss Equation
The Universal Soil Loss Equation (USLE) is a widely used mathematical model that describes soil erosion processes. Erosion models play critical roles in soil and water resource conservation and nonpoint source pollution assessments, including: sediment load assessment and inventory, conservation planning and design for sediment control, and for the advancement of scientific understanding. The USLE or one of its derivatives are main models used by United States government agencies to measure water erosion. The USLE was developed in the U.S., based on soil erosion data collected beginning in the 1930s by the U.S. Department of Agriculture (USDA) Soil Conservation Service (now the USDA Natural Resources Conservation Service). The model has been used for decades for purposes of conservation planning both in the United States where it originated and around the world, and has been used to help implement the United States' multibillion-dollar conservation program.

United States Geological Survey
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of planets and moons, based on data from U.S. space probes. The sole scientific agency of the U.S. Department of the Interior, USGS is a fact-finding research organization with no regulatory responsibility. It is headquartered in Reston, Virginia, with major offices near Lakewood, Colorado; at the Denver Federal Center; and in NASA Research Park in California. In 2009, it employed about 8,670 people. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on its hundredth anniversary, was "Earth Science in the Pub ...

California Department Of Water Resources
The California Department of Water Resources (DWR) is part of the California Natural Resources Agency and is responsible for the management and regulation of the State of California's water usage. The department was created in 1956 by Governor Goodwin Knight following severe flooding across Northern California in 1955, where they combined the Division of Water Resources of the Department of Public Works with the State Engineer's Office, the Water Project Authority, and the State Water Resources Board. It is headquartered in Sacramento. History 1850-1875 California recognizes many types of water rights. Prior to the Treaty of Guadalupe Hidalgo, signed in 1848, California was part of Mexico. Riparian rights were the most prevalent type of water right. Under riparian rights, which have their origins in Roman law, a landowner can use water flowing by his property for use on his property. When California became part of the United States, the United States agreed to recognize exis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salinity
Salinity () is the saltiness or amount of salt (chemistry), salt dissolved in a body of water, called saline water (see also soil salinity). It is usually measured in g/L or g/kg (grams of salt per liter/kilogram of water; the latter is dimensionless and equal to per mille, ‰). Salinity is an important factor in determining many aspects of the chemistry of natural waters and of biological processes within it, and is a state function, thermodynamic state variable that, along with temperature and pressure, governs physical characteristics like the density and heat capacity of the water. A contour line of constant salinity is called an ''isohaline'', or sometimes ''isohale''. Definitions Salinity in rivers, lakes, and the ocean is conceptually simple, but technically challenging to define and measure precisely. Conceptually the salinity is the quantity of dissolved salt content of the water. Salts are compounds like sodium chloride, magnesium sulfate, potassium nitrate, and sod ...

Energy Biosciences Institute
The Energy Biosciences Institute (EBI) is an organization dedicated to developing new sources of energy and reducing the impact of energy consumption. It was created in 2007 to apply advanced knowledge of biology to the challenges of responsible, sustainable energy production and use. Its main goal is to develop next-generation biofuels—that is, biofuels that are made from the non-edible parts of plants and reduce greenhouse gas emissions. Funded by BP, which initially agreed to contribute $500 million over a 10-year-period, with $350 million slated for academic research, EBI is a joint initiative between the University of California, Berkeley (UCB), Lawrence Berkeley National Laboratory, the University of Illinois at Urbana-Champaign, and the energy company. It is the largest public-private venture of its kind. All research from its academic labs is published and publicly available. More information about the EBI is available to the public through the EBI Bulletin and its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Algae Fuel
Algae fuel, algal biofuel, or algal oil is an alternative to liquid fossil fuels that use algae as the source of energy-rich oils. Also, algae fuels are an alternative to commonly known biofuel sources, such as corn and sugarcane. When made from seaweed (macroalgae) it can be known as seaweed fuel or seaweed oil. These fuels have no practical significance but remain an aspirational target in the biofuels research area. History In 1942 Harder and Von Witsch were the first to propose that microalgae be grown as a source of lipids for food or fuel. Following World War II, research began in the US, Germany, Japan, England, and Israel on culturing techniques and engineering systems for growing microalgae on larger scales, particularly species in the genus '' Chlorella''. Meanwhile, H. G. Aach showed that '' Chlorella pyrenoidosa'' could be induced via nitrogen starvation to accumulate as much as 70% of its dry weight as lipids. Since the need for alternative transportation fuel h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Algae
Algae ( , ; : alga ) is an informal term for any organisms of a large and diverse group of photosynthesis, photosynthetic organisms that are not plants, and includes species from multiple distinct clades. Such organisms range from unicellular microalgae, such as cyanobacteria, ''Chlorella'', and diatoms, to multicellular macroalgae such as kelp or brown algae which may grow up to in length. Most algae are aquatic organisms and lack many of the distinct cell and tissue types, such as stomata, xylem, and phloem that are found in embryophyte, land plants. The largest and most complex marine algae are called seaweeds. In contrast, the most complex freshwater forms are the Charophyta, a Division (taxonomy), division of green algae which includes, for example, ''Spirogyra'' and stoneworts. Algae that are carried passively by water are plankton, specifically phytoplankton. Algae constitute a Polyphyly, polyphyletic group because they do not include a common ancestor, and although Eu ...

Kesterson Reservoir
The Kesterson Reservoir is part of the current San Luis National Wildlife Refuge in California. Formerly a unit of the Kesterson National Wildlife Refuge, the reservoir was an important stopping point for migratory waterfowl. Kesterson once consisted of 12 evaporation ponds totaling approximately 1,280 acres, and was historically used for agricultural drainage. Kesterson gained national attention during the latter half of the 20th century due to selenium toxicity and rapid die off of migratory waterfowl, fish, insects, plants and algae. The reservoir was closed in 1986, and concentrations of selenium at the site have continued to be monitored throughout remediation efforts. Background The Kesterson National Wildlife Refuge is located approximately 18 miles west of Merced County in the San Luis National Wildlife Refuge, in the San Joaquin Valley of central California. The refuge is 26,609 acres (107.68 km2) and includes a variety of wetland and riparian habitat which su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
