The Tree Fruit Research and Extension Center (WTFREC), located in Wenatchee, Washington, includes a former U.S. Public Health Service/EPA pesticide test plot area and a laboratory drain field, in addition to an active university tree fruit research and extension center. As a result of pesticide weathering experiments the test plot had been contaminated with organochlorine, organophosphorus, and other pesticides above known levels of concern for human health and the environment. The US Environmental Protection Agency (EPA), Washington State University (the current property owner), and Washington Department of Ecology determined that remediation of the test plot area was necessary. The EPA requested the U.S. Army Corps of Engineers, Seattle District (USACE), to propose, design, and implement the characterization and remediation.

For more than a century, a large volume of gold-mining tailings was deposited in Whitewood Creek and the Belle Fourche River, tributaries to the Cheyenne River in western South Dakota. Much of it still remains, and field and historical evidence indicates continued remobilization of tailings-containing alluvium in these bedrock-dominated channels. Both long-term, natural fluctuations in climate and anthropogenically driven changes can impact regional precipitation, temperature, hydrologic patterns, and ecosystem functions. Such changes have the potential to affect both the transport and distribution of arsenic-laden sediments and mechanical erosion that can undermine the stability of channel-bed and overbank material. This study reevaluates published literature and simulates future climatic conditions with Global Change Models downscaled to hydrologic models to detect trends and determine if they differ from historical time series data or exhibit non-stationarity. Arsenic concentrati...

This paper describes building information modeling (BIM) research by students and faculty of the University of Nebraska’s Peter Kiewit Institute (PKI). The paper also describes work in conjunction with the United States Strategic Command (USSTRATCOM), located at Offutt Air Force Base in Omaha, Nebraska, USA. The objective of this on-going research is to create a virtual modeling environment where architects and planners can present building concepts and design options to customers in a way that is more easily envisioned by the client. The proposed environment would integrate BIM and virtual environments by allowing a free exchange of data between applications. The specific research mentioned in this paper focuses on visualization and editing of interior room configurations for use by USSTRATCOM. The software used for this research project was Autodesk Revit, Autodesk 3DS Max, and a proprietary gaming engine called Unity, developed by Unity Technologies and based in San Francisco, Ca...
