A broad survey of regional patterns in stream flow nationwide. Maps and graphs summarizing streamflow conditions for water-year 2011 (October 1, 2010 to September 30, 2011) in the context of the 82-year period 1930-2011.
Methods to depict the connectedness of rock units across fault and fracture zones, allowing us to determine the distribution of geologic units, structural features, and other controlling factors, such as porosity and permeability.
We use moderate resolution satellite data to assess live fuel condition for estimating fire danger. Using 23 years of vegetation condition measurements, we are able to determine the relative greenness of wildland vegetation susceptible to burning.
About 355,000 million gallons per day of water was withdrawn for use in the United States during 2010, a decline of 13 percent from 2005 and a substantial change from the level of about 400,000 reported from 1985 to 2005.
We estimated mean technically-recoverable undiscovered continuous and conventional resources that total 495 million barrels of oil, 27.5 trillion cubic feet of natural gas, and 410 million barrels of natural gas liquids in this area.
