Analysis of sea-surface temperature in the Indian Ocean shows that warming correlates with east African rainfall; the effect on atmospheric convection and precipitation over the Indian Ocean is greater than that associated with El Niño (ENSO).
Research exploring the mathematical properties of kriging, a widely-used surface interpolation method. The continuity properties of kriging digital terrain models over a wide range of terrain types helps hydrologists assess the usefulness of kriging for D
Annual peak flows have increased at most rivers in Maine during the last century. What effect does this have on computed peak flows, such as the 100-year flows, that are used for designing bridges and other structures?
Provides standards and guidance for measuring, estimating, collecting, and analyzing water-use data. Includes brief descriptions of water-use activities, commonly used water-use terminology, and approaches and methods used in estimating water use.
Report on the use of regression equations from measurements made by water quality monitors and analytical results of manually collected samples estimating nutrient, bacteria, and other constituent concentrations to study streams in Kansas.
Research projects intended to create regional and national data that conform to conditions predicted by general circulation models, so that land and wildlife managers can understand the likely consequences of climatic changes in their areas of study.
Overview of the Southeastern Amphibian Research and Monitoring Initiative, annual report, field methods and protocols, statistical design and analysis, glossary, projects, and lists of frogs, toads and salamanders.
Streamflow statistics and basin characteristics for most streams in specific US states using the Streamstats program. Data for areas can be selected from interactive maps and by an automated process. Includes a tutorial.
Types and quantities of raw materials used by U.S. manufacturers and consumers, which have changed significantly as the economy has moved from one that is predominantly agricultural to one that is primarily industrial.
