US Army Corps of Engineers - Portland District required that a two-dimensional (2D) depth-averaged and a three-dimensional (3D) free-surface numerical models to be developed and validated for the John Day tailrace. These models were used to assess potential impact of a select group of structural and operational alternatives to tailrace flows aimed at improving fish survival at John Day Dam. The 2D model was used for the initial assessment of the alternatives in conjunction with a reduced-scale physical model of the John Day Project. A finer resolution 3D model was used to more accurately model the details of flow in the stilling basin and near-project tailrace hydraulics. Three-dimensional model results were used as input to the Pacific Northwest National Laboratory particle tracking software, and particle paths and times to pass a downstream cross section were used to assess the relative differences in travel times resulting from project operations and structural scenarios for multiple total river flows. Streamlines and neutrally-buoyant particles were seeded in all turbine and spill bays with flows. For a Total River of 250 kcfs running with the Fish Passage Plan spill pattern and a spillwall, the mean residence times for all particles were little changed; however the …

This document reports the findings of the groundwater and leachate monitoring and sampling at the Environmental restoration Disposal Facility for calendar year 2009. The purpose of this annual monitoring report is to evaluate the conditions of and identify trends for groundwater beneath the ERDF and report leachate results in fulfillment of the requirements specified in the ERDF ROD and the ERDF Amended ROD.

As a part of the Waste Acceptance Product Specifications (WAPS) for Vitrified High-Level Waste Forms defined by the Department of Energy - Office of Environmental Management, the waste form stability must be determined for each of the projected high-level waste (HLW) types at the Savannah River Site (SRS). Specifically, WAPS 1.4.1 requires the glass transition temperature (T{sub g}) to be defined and time-temperature-transformation (TTT) diagrams to be developed. The T{sub g} of a glass is an indicator of the approximate temperature where the supercooled liquid converts to a solid on cooling or conversely, where the solid begins to behave as a viscoelastic solid on heating. A TTT diagram identifies the crystalline phases that can form as a function of time and temperature for a given waste type or more specifically, the borosilicate glass waste form. In order to assess durability, the Product Consistency Test (PCT) was used and the durability results compared to the Environmental Assessment (EA) glass. The measurement of glass transition temperature and the development of TTT diagrams have already been performed for the seven Defense Waste Processing Facility (DWPF) projected compositions as defined in the Waste Form Compliance Plan (WCP) and in SRNL-STI-2009-00025. Additional phase transformation information …

This report discusses the United States counterterrorism cooperation with China after the terrorist attacks on September 11, 2001. This effort raised short-term policy issues about how to elicit cooperation and how to address China's concerns about military action (Operation Enduring Freedom). Longer-term questions have concerned whether counterterrorism has strategically transformed bilateral relations and whether China's support has been valuable and not obtained at the expense of other U.S. interests.

The purpose of this annual report is to evaluate the conditions and identify trends to develop Hanford Site specific data on the performance of the lysimeter systems related to the vadose zone monitoring and potential future use of lysimeter systems.

This report is categorized into two categories: (I) Agriculture in the Tax Extenders Bill (H.R. 4213) and (II) Agriculture in the Supplemental Appropriations Bill (H.R. 4899).

Congress has expressed a great deal of interest in using Unmanned Aerial Vehicles (UAVs) to surveil the United States' international land border. U.S. Customs and Border Protection (CBP) utilizes advanced technology to augment its USBP agents' ability to patrol the border, including a fleet of six UAVs. This report examines the strengths and limitations of deploying UAVs along the borders and related issues for Congress.

This report provides background on events leading up to and surrounding the country's most recent elections, in March and June 2008.

The 111th Congress may elect to consider legislation (H.R. 500 and S. 237) that has been introduced to amend and reauthorize the Nonindigenous Aquatic Nuisance Prevention and Control Act of 1990 to further study vessel ballast water management standards and modify how ballast water is handled. This report provides background on various approaches to ballast water management and reviews current ballast water management laws and programs.

The Navy has been procuring Virginia (SSN-774) class nuclear-powered attack submarines (SSNs) at a rate of one per year for the past several years, and a total of 12 boats have been procured through FY2010. The Navy's proposed FY2011 budget increases the procurement rate to two boats per year. This report discusses the Navy's proposed FY2011 budget, which requests $3,441.5 million in procurement funding to complete the procurement cost of the 13th and 14th Virginia-class boats.

The U.S. program of assistance to Afghanistan is intended to stabilize and strengthen the Afghan economic, social, political, and security environment so as to blunt popular support for extremist forces in the region. Since 2001, nearly $48 billion has been appropriated toward this effort. This report provides a "big picture" overview of the U.S. aid program and congressional action. It describes what various aid agencies report they are doing in Afghanistan. It does not address the effectiveness of their programs.
