The Sinmap Approach To Terrain Stability Mapping, Robert T. Pack, David G. Tarboton, C. N. Goodwin

Civil and Environmental Engineering Faculty Publications

A promising approach to modeling the spatial distribution of shallow debris slides combines a mechanistic infinite slope stability model with a steady-state hydrology model. The spatial distribution of a “stability index” is governed primarily by specific catchment area (the upslope area per unit contour length) and slope. The model can be interactively calibrated to the unique characteristics of the topography, rainfall, and soils of a particular study area using simple parameters, graphs and maps. Once a landslide and terrain inventory is completed using aerial photographs, this approach is shown to have the capability of producing a stability classification map of …

United States Environmental Protection Agency: Publications

This report summarizes the findings of an evaluation of sprinkler irrigation as a volatile organic compound (VOC) separation and disposal method.

Background A need for lower cost, effective treatment alternatives for the disposal of treated contaminated groundwater provided the impetus to conduct a SITE demonstration of sprinkler irrigation since it provides both separation and disposal options. Since the application of irrigation is fairly widespread throughout the United States, there may be an opportunity to employ this as a dual purpose technology; concurrent irrigation and disposal of treated groundwater. In order to determine whether this option is viable, it is necessary …

Climate Change And Nebraska

United States Environmental Protection Agency: Publications

The earth’s climate is predicted to change because human activities are altering the chemical composition of the atmosphere through the buildup of greenhouse gases — primarily carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons. The heat-trapping property of these greenhouse gases is undisputed. Although there is uncertainty about exactly how and when the earth’s climate will respond to enhanced concentrations of greenhouse gases, observations indicate that detectable changes are under way. There most likely will be increases in temperature and changes in precipitation, soil moisture, and sea level, which could have adverse effects on many ecological systems, as well as on …
