Geologic impacts of the 2004 Indian ocean tsunami on Indonesia, Sri Lanka, and the Maldives Geologic impacts of the 2004 Indian ocean tsunami on Indonesia, Sri Lanka, and the Maldives
The December 26, 2004 Indian Ocean tsunami was generated by a large submarine earthquake (magnitude ???9.1) with an epicenter located under the seafloor in the eastern Indian Ocean near northern Sumatra, Indonesia. The resulting tsunami was measured globally and had significant geologic impacts throughout the Indian Ocean basin. Observations of tsunami impacts, such as morphologic change

Geophysical evaluation of the Success Dam foundation, Porterville, California Geophysical evaluation of the Success Dam foundation, Porterville, California
Success Dam is a zonedearth fill embankment located near Porterville, CA. Studies of Success Dam by the recent Dam Safety Assurance Program (DSAP) have demonstrated the potential for seismic instability and large deformation of the dam due to relatively low levels of earthquake shaking. The U.S. Army Corps of Engineers conducted several phases of investigations to determine the...

Ground-water surface-water interactions and long-term change in riverine riparian vegetation in the southwestern United States Ground-water surface-water interactions and long-term change in riverine riparian vegetation in the southwestern United States
Riverine riparian vegetation has changed throughout the southwestern United States, prompting concern about losses of habitat and biodiversity. Woody riparian vegetation grows in a variety of geomorphic settings ranging from bedrock-lined channels to perennial streams crossing deep alluvium and is dependent on interaction between ground-water and surface-water resources. Historically...

Groundwater-supported evapotranspiration within glaciated watersheds under conditions of climate change Groundwater-supported evapotranspiration within glaciated watersheds under conditions of climate change
This paper analyzes the effects of geology and geomorphology on surface-water/-groundwater interactions, evapotranspiration, and recharge under conditions of long-term climatic change. Our analysis uses hydrologic data from the glaciated Crow Wing watershed in central Minnesota, USA, combined with a hydrologic model of transient coupled unsaturated/saturated flow (HYDRAT2D). Analysis of...

Guideline for assessing the performance of electric power systems in natural hazard and human threat events Guideline for assessing the performance of electric power systems in natural hazard and human threat events
Electric power utilities are familiar with and skilled in preparing for and responding to almost-routine natural hazard events such as strong wind and ice storms and seasonal floods, as well as intentional human acts such as vandalism. Recent extreme weather (hurricanes Katrina and Rita), extremely destructive international earthquakes (in Sumatra and Pakistan), and nation-wide concerns...

Habitat preferences and intraspecific competition in black-footed ferrets Habitat preferences and intraspecific competition in black-footed ferrets
We used radio-telemetry data (28,560 positional fixes) collected on 153 black-footed ferrets (Mustela nigripes) to (1) reexamine the assumed obligate relationship of these ferrets to prairie dogs (Cynomys spp.), (2) investigate habitat preferences of ferrets at a small scale (1 year (P = 0.048). Also, preference was stronger for wild-born young ferrets than for young captive-born ferrets...

High resolution tree-ring based spatial reconstructions of snow avalanche activity in Glacier National Park, Montana, USA High resolution tree-ring based spatial reconstructions of snow avalanche activity in Glacier National Park, Montana, USA
Effective design of avalanche hazard mitigation measures requires long-term records of natural avalanche frequency and extent. Such records are also vital for determining whether natural avalanche frequency and extent vary over time due to climatic or biophysical changes. Where historic records are lacking, an accepted substitute is a chronology developed from tree-ring responses to...

Hydrologic landscape units and adaptive management of intermountain wetlands Hydrologic landscape units and adaptive management of intermountain wetlands
daptive management is often proposed to assist in the management of national wildlife refuges and allows the exploration of alternatives as well as the addition of ne w knowledge as it becomes available. The hydrological landscape unit can be a good foundation for such efforts. Red Rock Lakes National Wildlife Refuge (NWR) is in an intermountain basin dominated by vertical tectonics in...
