A comparison of nested quadrat and point-line intercept sampling methods for fire effects monitoring in shortgrass prairie A comparison of nested quadrat and point-line intercept sampling methods for fire effects monitoring in shortgrass prairie
Within the National Park Service (NPS) and other federal land-managing agencies, there has been widespread application of the use of standardized fire-effects monitoring protocols. While standardization is often desirable, researchers and managers have come to recognize that 1 method does not work in all habitats with regard to application and efficiency. In 1999, in response to a...

A model for spatially and temporally distributed shallow landslide initiation by rainfall infiltration A model for spatially and temporally distributed shallow landslide initiation by rainfall infiltration
We describe a model for regional initiation of shallow landslides based on an approximate analytic solution to Richards equation combined with an infinite-slope calculation. The model applied over digital topography computes pressure heads and factors of safety as functions of depth for geographic information system (GIS) grid cells at any time during and after rainfall events. An...

A proposed international watershed research network A proposed international watershed research network
An “International Watershed Research Network” is to be an initial project of the Sino-U. S. Centers for Soil and Water Conservation and Environmental Protection. The Network will provide a fundamental database for research personnel of the Centers, as well as of the global research community, and is viewed as an important resource for their successful operation. Efforts are under way to...

A science and technology initiative within the office of civilian radioactive waste management A science and technology initiative within the office of civilian radioactive waste management
In 2002, by following a national decision-making process that had been specified in the 1982 Nuclear Waste Policy Act, Yucca Mountain (YM) was designated as the site for the nation's geologic repository for commercial spent nuclear fuel (SNF). The U.S. Department of Energy's (DOE's) Office of Civilian Radioactive Waste Management (OCRWM) must now obtain regulatory approval to construct...

Adaptive Management Implementation: Glen Canyon Dam Adaptive Management Program Trinity River Restoration Program Adaptive Management Implementation: Glen Canyon Dam Adaptive Management Program Trinity River Restoration Program
Two adaptive management programs, the Glen Canyon Dam Adaptive Management Program (GCDAMP) and the Trinity River Restoration Program (TRRP) are examined. In both cases, the focus is on managing the aquatic and riparian systems downstream of a large dam and water supply project. The status of the two programs, lessons learned by the program managers and the Adaptive Environmental...

Analytical method for optimal source reduction with monitored natural attenuation in contaminated aquifers Analytical method for optimal source reduction with monitored natural attenuation in contaminated aquifers
A method is developed for optimizing monitored natural attenuation (MNA) and the reduction in the aqueous source zone concentration (??C) required to meet a site-specific regulatory target concentration. The mathematical model consists of two one-dimensional equations of mass balance for the aqueous phase contaminant, to coincide with up to two distinct zones of transformation, and...
