Hydrologic consequences of hot-rock/snowpack interactions at Mount St. Helens Volcano, Washington
Thomas C. Pierson
1999, Professional Paper 1586
Emplacement of hot volcanic debris onto a thick snowpack can trigger hazardous rapid flows of sediment (including ice grains) and water, which can travel far beyond the flanks of a volcano. Five papers in this volume document aspects of rapid-snowmelt events that occurred in Mount St. Helens between 1982 and...

1999, Continental Shelf Research (19) 335-361
Sediment inventories of the cosmogenic radionuclide 7Be (t1/2=53 d) were measured on the Eel River shelf and slope (northern California continental margin) to investigate sedimentation processes associated with coastal river flooding. Seabed coring shortly after major riverflow events in 1995 and 1997 documented a shelf-wide flood deposit, and subsequent radionuclide...

1999, Ecosystems (2) 395-410
Although limnologists have long been interested in regional patterns in lake attributes, only recently have they considered lakes connected and organized across the landscape, rather than as spatially independent entities. Here we explore the spatial organization of lake districts through the concept of landscape position, a concept that considers lakes...

The U.S. Army Alaska is responsible for environmental activities on Fort Wainwright near Fairbanks, Alaska. In order to better meet the needs of environmental investigations, the Army requires geohydrologic information about the Fort Wainwright area. Since 1994, the U.S. Geological Survey has been working in cooperation with the U.S. Army...

1999, Fact Sheet 086-99
MOC3D is a general-purpose computer model developed by the U.S. Geological Survey (USGS) for simulation of three-dimensional solute transport in ground water (Konikow and others, 1996). The model is an update to the widely used USGS two-dimensional solute-transport model (MOC) and is implemented as an optional “package” for the ground-water...
