Blast noise from military installations often has a negative impact on the quality of life of residents living in nearby communities. This, in turn, negatively impacts the military’s testing & training capabilities due to restrictions, curfews, or range closures enacted to address noise complaints. In order to more directly manage noise around military installations, accurate noise monitoring around bases has become a necessity. Although most noise monitors are simple sound level meters, more recent ones are capable of discerning blasts from ambient noise with some success. Investigators at the University of Pittsburgh (Pitt) developed a more advanced noise classifier that can discern between wind, aircraft, and blast noise, while simultaneously lowering the measurement threshold. Here, more recent work between Pitt and the US Army Engineer Research and Development Center will be presented from the development of a more advanced classifier that identifies additional classes of noise such as machine gun fire, vehicles, and electronic noise. Additional signal metrics were explored given the increased complexity of the classifier. By broadening the types of noise the system can accurately classify and increasing the number of metrics, a new system was developed with increased blast noise accuracy, decreased number of missed events, and significantly fewer false positives.

During the past several years, the US Army has focused considerable attention toward developing improved methods for breaching walls in the urban combat environment. A major thrust area is centered on finding improved methods to breach the toughest wall type that Army units are likely to face: a double (steel) reinforced concrete (RC) wall. One impediment to this effort is that the relationship between the contact explosive charge configuration and the quantity of concrete removed has not been thoroughly understood. The U.S. Army Engineer Research and Development Center has conducted a research effort to better define the effectiveness of various explosive charge configurations in breaching RC walls. This paper presents a discussion of results from this research.

Brigadier General Richard C. “Rich” Gross is the US Army Legal Counsel to the Chairman of the Joint Chiefs of Staff. He attended the Military Academy at West Point and was commissioned in the US Army as a second lieutenant in the Infantry. He also attended the University of Virginia School of Law and the US Army Judge Advocate General's Corps. He holds a Master's degree in strategic studies from the US Army War College. Prior to his current position, he served as the Chief Legal Adviser for the Joint Special Operations Command, the International Security Assistance Force (ISAF), US Forces-Afghanistan (USFOR-A) and at US Central Command.The scope of application of international humanitarian law (IHL) is a deceptively simple concept; broadly speaking, it is where, when and to whom the IHL rules apply. Although this has always been a precondition for discussing IHL issues, the outer limits of the law's applicability remain unsettled. To open this issue on the nuances of the scope of the law's application, Brigadier General Gross gave the following interview providing the US perspective on the circumstances in which IHL applies, and the challenges that lie ahead in light of the ongoing evolution of the way war is waged.

This report details a study investigating the environmental impacts associated with the development and manufacturing of carbon nanotube (CNT)–based ink (called CNTRENE 1030 material) and novel CNT temperature, flex, and moisture sensors. Undertaken by a private-public partnership involving Brewer Science (Rolla, Missouri), Jordan Valley Innovation Center of Missouri State University (Springfield, Missouri), and the US Army Engineer Research and Development Center (Vicksburg, Mississippi), this work demonstrates the environmental life cycle assessment (ELCA) methodology as a diagnostic tool to pinpoint the particular processes and materials posing the greatest environmental impact associated with the manufacture of the CNTRENE material and CNT-based sensor devices. Additionally, ELCA tracked the degree to which optimizing the device manufacturing process for full production also changed its predicted marginal environmental impacts.

The Brunswick area consists of many acres of estuarine and marsh environments. The US Army Corps of Engineers District, Savannah, requested that the US Army Engineer Research and Development Center, Coastal and Hydraulics Laboratory, develop a validated Adaptive Hydraulics model and assist in using it to perform hydrodynamic modeling of proposed navigation channel modifications. The modeling results are necessary to provide data for ship simulation. The model setup and validation are presented here.

Logistical and combat operations in riverine, estuarine, and coastal environments remain a key military focus due to limited maneuverability, imperfect knowledge, and rapidly changing constraints. Vessel operation in water environments can be enhanced by routing algorithms that integrate mission parameters with environmental data and vessel specifications. These algorithms must update predetermined routes in a timely manner as parameters and specifications change. The US Army Engineer Research and Development Center Coastal and Hydraulics Laboratory is developing the capability for military planners to rapidly optimize vessel routes in water environments by extending capabilities of the Rapid Operational Access and Maneuver Support (ROAMS) modeling platform. The ROAMS platform allows users to rapidly generate models of a water environment in limited-information conditions, utilizing the Adaptive Hydraulics and STeady-state spectral WAVE computational engines for the base two-dimensional hydrodynamics and waves, respectively. Routing capabilities are built on path search and penalty-barrier optimization to automatically produce routes that account for temporally changing environmental variables and vessel maneuverability. This work outlines the components of the ROAMS routing package and presents a case study using ROAMS in a northeastern American metropolitan area. Benefits and limitations of the ROAMS routing platform are discussed and future improvements are suggested.

The Houston Ship Channel (HSC) is one of the busiest deep-draft navigation channels in the United States and must be able to accommodate increasing vessel sizes. The US Army Engineer District, Galveston (SWG), requested the Engineer Research and Development Center, Coastal and Hydraulics Laboratory, perform hydrodynamic and sediment modeling of proposed modifications in Galveston and Trinity Bays and along the HSC. The modeling results are necessary to provide data for hydrodynamic, salinity, and sediment transport analysis. SWG provided three project alternatives that include closing Rollover Pass, Bay Aquatic Beneficial Use System cells, Bird Islands, and HSC modifications. These alternatives and a Base (existing condition) will be simulated for present (2029) and future (2079) conditions. The results of these alternatives/conditions as compared to the Base are presented in this report. The model shows that the mean salinity varies by 2–3 ppt due to the HSC channel modifications and by approximately 5 ppt in the area of East Bay due to the closure of Rollover Pass. The tidal prism increases by 2.5% to 5% in the alternatives. The tidal amplitudes change by less than 0.01 m. The residual velocity vectors vary in and around areas where project modifications are made.

Watershed management increasingly requires ecohydraulic modeling and assessment within a regional context, rather than on a project-by-project basis. Such holistic modeling and assessment require evaluation capabilities across multiple temporal and spatial scales. Thus, modeling and assessment tools must be integrated in a scientifically and computationally effective infrastructure. The US Army Engineer Research and Development Center, in concert with the Hydrologic Engineering Center and its academic partners, including Brigham Young University, is establishing a comprehensive set of hydroinformatics modeling and assessment tools for ecohydraulic and water resources management applications, all linked based on a common data and information infrastructure. This paper presents the attributes of this information infrastructure and compares it with the analogous integration initiatives elsewhere.
