Debris-flow susceptibility of watersheds recently burned by wildfire
S.H. Cannon
2004, Conference Paper, Watershed Management and Operations Management 2000
Evaluation of the erosional response of 95 recently burned watersheds in Colorado, New Mexico, and southern California to storm rainfall established the factors that best differentiate between debris-flow producing basins and those that produced other flow responses. These factors are drainage-basin morphology and lithology, and the presence or absence of...
Louisiana's barrier islands: A vanishing resource
Jefferey H. List
2004, Report
Louisiana's barrier islands are eroding so quickly that according to some estimates they will disappear by the end of this century. Although there is little human habitation on these islands, their erosion may have a severe impact on the environment landward of the barriers. As the islands disintegrate, the vast...

Tectonic framework and Late Cenozoic tectonic history of the northern part of Cyprus: Implications for earthquake hazards and regional tectonics
Richard W. Harrison, Wayne L. Newell, Hilmi Batihanli, Ioannis Panayides, John McGeehin, Shannon A. Mahan, Ayse Ozhur, Efthymios Tsiolakis, Mehmet Necdet
2004, Journal of Asian Earth Sciences (23) 191-210
Located near the triple junction of the African, Arabia, and Eurasian Plate, Cyprus has had an active and complex neotectonic history, which includes devastating historical earthquakes. Investigations into the tectonic framework of the northern part of Cyprus provide important insights into regional tectonism of the Eastern Mediterranean and Middle East....

2004, Report
Eighteen of the 124 species of mammals inhabiting Colorado are bats. The unique life history characteristics of bats prevent many people from realizing that they comprise 15 percent of our native mammal fauna. Being fast fliers that are active at night, bats are mostly elusive to human senses except in...
Using discrete choice modeling to generate resource selection functions for female polar bears in the Beaufort Sea

Snehalata Huzurbazar, editor(s)
2004, Conference Paper, Resource selection methods and applications: Proceedings of the 1st International Conference on Resource Selection
Polar bears (Ursus maritimus) depend on ice-covered seas to satisfy life history requirements. Modern threats to polar bears include oil spills in the marine environment and changes in ice composition resulting from climate change. Managers need practical models that explain the distribution of bears in order to assess the...
The Parkfield experiment; capturing what happens in an earthquake

2004, Fact Sheet 049-02
To better understand what happens on and near a fault before, during, and after an earthquake, the U.S. Geological Survey (USGS) and the California Geological Survey began the Parkfield Earthquake Experiment in the 1980's. Researchers from the USGS and collaborating institutions have created a dense network of instruments on the...
