Abstract:
Theodore Roosevelt made reform of the U.S. Army Officer Corps a priority during his presidency. He felt compelled to act because of the problems that the army experienced during the war with Spain. As a volunteer soldier, Roosevelt had witnessed the shortcomings of many of the top-ranking officers in meeting the physical and organizational demands of the fighting, but he also acted because he wanted high-minded, intelligent, and physically fit leaders who could inspire his fellow citizens to a greater sense of duty in post-frontier America. Roosevelt's efforts to promote promising army officers to top commands and mandate physical fitness standards would prove disruptive, as he elevated officers out of the normal line of promotion. These practices would, in turn, generate protests in Congress and from within the military. The resulting controversies would cause Roosevelt to fall short of his goals for improving army leadership, roil civil-military relations, and demonstrate his limits as a political leader.

Abstract:
To create and maintain a navigable entrance for small craft between the Pacific Ocean and the natural lagoon now referred to as Bodega Harbor, the construction of two rubble-mound jetties and the associated dredging of interior channels were authorized by the United States Congress in the late 1930s. The jetties were built by the United States Army Corps of Engineers in the early 1940s. Elements of the planning, design, construction, monitoring, and maintenance of the jetties are discussed herein.

Abstract:
This article reconsiders early American state capacity through a close examination of the U.S. Army Corps of Topographical Engineers. The topographical corps, a bureau in the antebellum War Department, developed a form of conditional bureaucratic autonomy far earlier than recognized in previous scholarship, giving it a central role in shaping national economic development policies, especially in the nation's periphery. Unlike robust bureaucratic autonomy, such as that described by Daniel Carpenter (2001, 2010; see footnote 4), conditional autonomy is highly contingent and can quickly fracture if the surrounding environment changes. The long-serving chief of the corps, Col. John J. Abert, shaped the opinions of his supposed principals by managing the ideas, information, and proposals directed to them. When faced with challenges, the corps proved to be a flexible organization that adapted its methods to accomplish its preferred ultimate goals using different instruments. In the end, however, the corps' autonomy was threatened when it became involved in the sectional politics surrounding the potential building of a transcontinental railroad line. Once the corps lost several of the conditions supporting its autonomy, its downfall was swift. This article thus joins a recent wave of scholarship highlighting strengths within the early American state by foregrounding the role of the armed forces in statebuilding.

Abstract:
If statesmanship can be characterized as a bed rock of principles, a strong moral compass, a vision, and an ability to articulate and effect that vision, then the fortitude, tenacity, imperturbability, and resilience of William Crawford Gorgas cannot be overestimated. As Chief Sanitary Officer in Cuba and as Chief Medical Officer in Panama, he actualized strategies to eradicate the vectors of yellow fever and malaria. His superiors initially pigeonholed his requisitions, refused to provide him with any authority, and clamored for his dismissal. Nevertheless, with dogged persistence he created a coalition of the willing, who eventually implemented those reforms. As Surgeon General in the United States Army, he organized and expanded the Active Duty and Medical Reserve Corps in anticipation of World War I. Skilled university affiliated surgeons and personnel from throughout North America, manned base hospitals in Europe. Those lessons impacted upon subsequent military and civilian surgical care—organizationally, logistically, and clinically. He was universally recognized for his bonhomie, savoir-faire, modesty, discretion, decorum, courtesy, and graciousness. To those attributes must be added his devotion to duty, discipline, integrity, and authenticity, which characterized his leadership and statesmanship. Those attributes are most worthy of emulation and perpetuation by clinicians, academicians, educators, and investigators.

Abstract:
Military service has long been seen as one of the few routes available to African American men to demonstrate their rights to full citizenship. In 1942, the Women’s Army Corps (wac) opened this path for black women. More than 6,500 black Wacs served during the Second World War, yet, marginalized while in uniform and later overshadowed in narratives of black servicemen and white servicewomen, they and their unique experiences remain largely unknown outside of academia. This article examines the multiple subordinate positions to which the United States Army confined black Wacs, as black female soldiers, during the first years of the corps; investigates the army’s gender and racial policies and their civilian and military roots; and forefronts the actions of black Wacs who, by challenging their subordination, laid claim to their full rights as soldiers and as citizens.

Abstract:
The Battle of Okinawa was the last major ground battle of World War ii. The Tenth u.s. Army that invaded this small piece of Japan was a unique force composed of units from the u.s. Army and others from the u.s. Marine Corps. Much historical literature has focused on the different approaches to ground combat of the two armed services, but they also employed very different policies towards support of the news media. The u.s. Marines were much more supportive than the u.s. Army. The two different policies and styles of news coverage that reporters employed led to coverage favoring the u.s. Marines. Reporting suggested that u.s. Marine procedures were less costly in lives and created enormous concern in the United States about casualty rates, motivating President Harry S. Truman to hold an Oval Office meeting to re-think strategy in the Pacific theater. It would be wrong, though, to argue that the media altered the course of the war. Truman asked hard probing questions about the direction of the war, but General of the Army George C. Marshall acted to ensure that the United States stayed on its current strategic path.

Abstract:
World War II was the most devastating war in human history in terms of loss of life. The Japanese attack on Pearl Harbor on December 7, 1941, plunged the United States into war. Less than seven thousand military nurses were on active duty at the time of the attack. By the end of the war, there were over fifty-thousand active-duty nurses. The army nurses performed under fire in field and evacuation hospitals, on hospital trains and ships, and as flight nurses on medical evacuation transport aircraft. The skill and dedication of the Army Nurses Corps insured a 95% survival rate for the wounded soldiers who received medical care in a field or evacuation hospital. Two hundred and one nurses lost their lives during World War II and sixty-seven nurses were captured and held as prisoners of war. Sixteen hundred medals, citations and commendations attest to the nurses’ courage and dedication.

Abstract:
AbstractIran’s grand strategy revolves around three key pillars: regime’s survival, security, stability (S3). Viewing the United States, and to a lesser extent Israel, as enduring state threats aiming to disrupt S3, Tehran has increasingly prioritized asymmetric tactics in its defense doctrine. This approach aims to deter adversaries’ kinetic and non-kinetic operations while also positioning Iran to attain regional power status. The integration of AI into defense is seen as a force multiplier. Although Iran’s incorporation of AI into its defense capabilities and infrastructure remains in progress and lacks clarity, the regime is extensively focusing on enhancing its missile systems, proxy forces, Uncrewed Aerial Vehicles (UAVs), and naval power with AI technologies. Beyond state deterrence, Iran’s 360-degree defense doctrine places emphasis on safeguarding national critical infrastructure and ensuring domestic stability, both of which have recently been bolstered through AI. The defense infrastructure in Iran operates through a multi-layered approach, predominantly involving the Islamic Revolutionary Guard Corps (IRGC), the Army, and the Ministry of Defense. Each entity maintains low-profile research and development (R&D) facilities aimed at advancing AI capabilities or integrating AI technologies into existing systems. Given Iran’s practice of denial and deception (D&D) techniques in its defense technology investments, the exact budget allocated for AI remains undisclosed. However, notwithstanding the opacity surrounding defense AI R&D and budgetary allocation, all defense academies currently engage in training students and recruiting researchers in military applications of AI, a testament to Iran’s vision to progressively integrate AI into its arsenals in the future.

The army established the VRC in April 1863 to boost its manpower shortage, utilizing disabled veterans to maintain order in northern towns and other rear echelon assignments. Eventually 57,000 enlisted men served in the Corps. Cimbala identifies various motives for wounded and camp-sick officers seeking commissions in the VRC.

Full text
Abstract:
Four demands have driven the development of policy analysis in the U.S. First, reformers have sought evidence to support their efforts. Beginning with the municipal bureaus of the Progressive Era, advocacy groups have sought supportive policy analysis, resulting in the proliferation of ideologically differentiated think tanks that produce policy research. Second, politicians have recognized the need for specialized expertise to address pressing problems. Operations research grew out of efforts to solve problems facing the U.S. in World War II and led to subsequent efforts to improve bureaucratic decision-making capacity. Third, the growing scope and complexity of government have led to a demand for information to support routine decision processes. Fiscal offices support state budgeting and the Congressional Budget Office, Government Accountability Office, and Congressional Research Service support the routine business of Congress. Fourth, politicians have sought to discipline their own (and especially others’) future actions by mandating that analyses be applied to certain classes of decisions. Legislative requirements that the Army Corps of Engineers consider the benefits of investment projects were introduced at the beginning of the last century, legislative requirements for the completion of environmental impact statements were imposed in 1970, and beginning in 1981, executive orders have required cost-benefit analyses be completed for major agency rulemakings. Higher education has responded to these demands by supplying persons trained specifically in policy analysis.

Meade ordered a division of Hancock’s Second Corps into the Wheatfield; he then ordered the divisions of United States Regulars, followed by the Pennsylvania Reserves, all from the Fifth Corps, into the Plum Run Valley to stop the Confederate attacks. Positioned north of the Wheatfield along Cemetery Ridge, Meade brought elements of the Twelfth Corps from the vulnerable right flank to enter the fighting north of the Wheatfield Road and to occupy positions along Cemetery Ridge. As darkness fell, Meade personally led elements of the First and Eleventh Corps, that had held positions on Cemetery Hill, to the center of the army along Cemetery Ridge where they stopped the last attack. By dark, all the Confederate attacks against the left and center of the army had been defeated.

Abstract:
This chapter traces the history of cost–benefit analysis in the United States bureaucracy from the 1920s until about 1960. It is not a story of academic research, but of political pressure and administrative conflict. Cost–benefit methods were introduced to promote procedural regularity and to give public evidence of fairness in the selection of water projects. Early in the century, numbers produced by the Army Corps of Engineers were usually accepted on its authority alone, and there was correspondingly little need for standardization of methods. About 1940, however, economic numbers became objects of bitter controversy, as the Corps was challenged by such powerful interests as utility companies and railroads. The really crucial development in this story was the outbreak of intense bureaucratic conflict between the Corps and other government agencies, especially the Department of Agriculture and the Bureau of Reclamation. The agencies tried to settle their feuds by harmonizing their economic analyses. When negotiation failed as a strategy for achieving uniformity, they were compelled to try to ground their makeshift techniques in economic rationality. On this account, cost–benefit analysis had to be transformed from a collection of local bureaucratic practices into a set of rationalized economic principles.

The British army evacuated from the United States over the course of the summer and fall of 1783. The departure resented many, though not all, members of the German corps with the choice of settling in America or going home. Ultimately, a few thousand men, women, and children remained in Canada and the United States. However, the vast majority returned to Germany. They were accompanied by several hundred Americans and Canadians, including wives and children of German soldiers. In addition, at least 200 Black men, women, and children went to Europe with German regiments during or at the conclusion of the war.

This chapter considers Harry White as a bit mysterious, citing one of John Maynard Keynes's biographers that regarded White as a remarkable figure that should be accorded an honourable place in British annals. In the United States, the FBI agents who investigated White extensively could not figure out whence his parents had emigrated, or what the family name had been. It mentions how White did little to dispel the mysteries, recounting how he never publicly explained the roots of his middle name that he took on himself as a teenager. The chapter recounts how Harry immediately enlisted in the U.S. Army and applied for enrollment in the Officers' Reserve Corps when the United States declared war on Germany and Austria-Hungary on April 6, 1917. The army sent Harry to Plattsburg Training Camp in upstate New York.

The chapter covers the early history of what will become known as the tank and the creation of the United States Tank Corps. Patton is the first “tanker” in American military history. After leaving the staff of John J. Pershing, Patton embarks on an educational journey to learn about tanks. He attends tank school in France and tours the Renault tank factory. It is here that he learns to drive a tank and selects the Renault light tank for use by the United States Army. The Renault tank is covered in detail, and Patton prepares to establish the American light tank school in France.

Abstract:
The aim of this research is to examine the safety culture of the United States Army Corps of Engineers staff and contractors working on marine construction projects including dredging, beach nourishment, breakwaters, and jetties. A literature review was performed to understand existing issues and to develop a research methodology for the study. Qualitative data research was used to uncover significant themes and help gain a deeper understanding of safety related issues. Twelve construction professions were interviewed using semi-structured interview format. The data was analysed using thematic analysis techniques with an inductive approach to draw conclusions. The results were used to conclude that issues causing safety accidents in the maritime construction sector can be broadly attributed to unforeseen conditions, training, complacency, lack of support of safety and crew unpreparedness. Data from the interviews also indicates ways to improve maritime construction can be broadly categorised under training, improved communication, improved preparation and organisational support for safety.

Abstract:
The mission of the United States Military Academy (USMA) is “To educate, train, and inspire the Corps of Cadets so that each graduate is a commissioned leader of character committed to the values of Duty, Honor, Country; professional growth throughout a career as an officer in the United States Army; and a lifetime of selfless service to the nation.” [1] The academic program at the USMA is designed to meet the intellectual demands of this mission statement. One very unique aspect of this academic program is the requirement that each cadet take a minimum of five engineering courses regardless of his or her major or field of study. Because of this requirement, nearly one-third of every graduating class take Fluid Mechanics. The Fluid Mechanics course taught in the USMA’s Department of Civil and Mechanical Engineering differs from others throughout the country for two primary reasons: 1) Within every class there is a mixture of cadets majoring in engineering and those who are in other majors, such as languages, history, and political science, 2) Each cadet will be commissioned as a Second Lieutenant in the United States Army immediately upon graduation, [2] and [3]. In this course cadets learn about fluid mechanics and apply the principles to solve problems, with emphasis placed upon those topics of interest to the Army and Army systems that they will encounter as future officers. The course objectives are accomplished through four principal methods. The first is through engaging, interactive classroom instruction. Cadets learn about the principles of fluid statics, conservation laws, dimensional analysis, and external flow; specialized topics, such as compressible flow and open channel flow have also been integrated. The second method is through hands-on laboratory exercises. Pipe friction, wind tunnels, and smoke tunnels are examples of laboratories in which cadets take experimental measurements, analyze data, and reinforce concepts from the classroom. The third method occurs in the “Design of an Experiment” exercise. In groups, cadets design their own experiment—based upon an Army parachutist—that will predict the coefficient of drag of a parachute system. The fourth method is a hands-on design project that culminates in a competition. In teams, cadets build a water turbine to lift a weight on a pulley from ground level to a designated height. Competition categories include the torque competition, in which maximum lifted weight determines the winner and the power competition judged by minimum time to lift a designated weight. This project, implemented within the curriculum prior to formal instruction on the design process, requires cadets to develop their own design process through analysis, experimentation, and trial and error.

Abstract:
The mission of the United States Military Academy (USMA) is “To educate, train, and inspire the Corps of Cadets so that each graduate is a commissioned leader of character committed to the values of Duty, Honor, Country; professional growth throughout a career as an officer in the United States Army; and a lifetime of selfless service to the nation.” [1] In order to accomplish this mission, USMA puts their cadets through a 47-month program that includes a variety of military training, and college courses totaling about 150 credit-hours. Upon completion of the program, cadets receive a Bachelor of Science degree and become Second Lieutenants in the United States Army. A very unique aspect of the academic program at USMA is that each cadet is required to take a minimum of five engineering classes regardless of their major or field of study. This means that about 500 cadets will have taken the one-semester course in thermodynamics. The thermodynamics course taught at USMA is different from others throughout the country because within every class there is a mixture of cadets majoring in engineering and those that are in other majors, i.e. languages, history [2]. Topics on gas turbine machinery have been integrated into this unique thermodynamics course. Because the cadets will encounter gas turbines throughout their service in the Army, we feel that it is important for all of the students, not just engineering majors, to learn about gas turbines, their operation, and their applications. This is accomplished by four methods. The first is in a classroom environment. Cadets learn how actual gas turbines work, how to model them, and learn how to solve problems. Thermodynamics instructors have access to several actual gas turbines used in military applications to aid in cadet learning. The second method occurs in the laboratory where cadets take measurements and analyze an operational auxiliary power unit (APU) from an Army helicopter. The third method occurs in the form of a design project. The engineering majors redesign the cogeneration plant that exists here at West Point. Many of them use a topping cycle in this design. The final method is a capstone design project. During the 2001–02 academic year, three cadets are improving the thermodynamic laboratories. Among their tasks are designing a new test stand for the APU, increasing the benefit of the gas turbine laboratory through more student interaction, and designing a web-based gas turbine pre-laboratory instruction to compliment the actual laboratory exercise.

Abstract:
Abstract Variable, renewable energy (VRE) generation such as solar power has seen a rapid increase in usage over the past decades. These power generation sources offer benefits due to their low marginal costs and reduced emissions. However, VRE assets are not dispatchable, which can result in a mismatch of the electric supply and demand curves. Pumped-storage hydropower (PSH) seeks to solve this by pumping water uphill during times of excess energy production and releasing the water back downhill through turbines during energy shortages, thus serving as a rechargeable battery. Creating new PSH systems, however, requires a large amount of capital and suitable locations. The United States Army Corps. of Engineers (USACE) is the largest producer of hydroelectric power within the United States, and as such, may have favorable sites for the addition of PSH. This study seeks to develop a method for evaluating these existing hydroelectric facilities using techno-economic methods to assess the potential for adding PSH. Each USACE facility was evaluated based on site specific characteristics from previously unpublished data to estimate the power generation and energy storage potential. The temporal nature of local wholesale electricity prices was accounted for to help estimate the financial feasibility of varying locations. Sensitivity analysis was performed to highlight how the method would identify the viability of facilities with different operational conditions. The methodologies detailed in this study will inform decision-making processes, and help enable a sustainable electric grid.

Full text
Abstract:
On June 5, 2007, the Environmental Protection Agency (EPA) and U.S. Army Corps of Engineers (Corps) issued joint guidance (herein the Rapanos Guidance) interpreting the U.S. Supreme Court’s divided Rapanos v. United States decision on the geographic extent of regulatory jurisdiction under Section 404 of the Clean Water Act. The technical document, “Jurisdictional Determination Form Instructional Guidebook” uses ambiguous language regarding implementation of the guidance manual. Pursuant to the Rapanos guidance, traditionally navigable waters (TNW), relatively permanent tributaries to these waters, and wetlands directly abutting such tributaries are “categorically” jurisdictional, while non-navigable tributaries that are not relatively permanent, wetlands adjacent to such tributaries, and wetlands that are adjacent to but do not directly abut a relatively permanent non-navigable tributary, are jurisdictional only if they have a “significant nexus” to a TNW. A critical issue for permit applications is whether the proposed activity will be subject to a categorical assertion of regulatory jurisdiction, or to a more involved “significant nexus analysis.” The scientific and environmental analyses of permit applications encountering a significant nexus analysis is designed to undergo additional review by the EPA. At the present time, the Guidance is deficient in providing definitive instruction for determining whether a significant nexus is present between a non-navigable tributary with non-permanent flow and a TNW. Our project allowed implementation of the Guidance and involved the installation of 264 miles of pipeline and permit negotiation with three separate Corps districts. Assessment of 483 streams and 189 wetlands was performed using the newly developed Jurisdictional Determination Forms. An interdisciplinary team approach was developed by integrating the knowledge bases of geographers and ecologists. Databases and maps were developed to allow collective assessment of potential waters of the U.S. within the context of the Rapanos ruling. Because of the Guidance’s ambiguity, it was necessary to develop a defensible approach with detailed concepts and terms to adequately implement the Jurisdictional Determination process to the satisfaction of regulators responsible for the implementation of the jurisdictional determination guidance manual.

Full text
Abstract:
Abstract In a previous study by Davis and Dequenne, a Holmquist-Johnson-Cook (HJC) constitutive model for a cellular concrete with a nominal density of 1442 kg/m3 was developed from existing direct tension, uniaxial strain, and triaxial shear testing conducted at the United States Army Corps of Engineers Engineer Research and Development Center (ERDC) and Sandia National Laboratory (SNL). The resulting constitutive model was compared to depth of penetration results from testing conducted by Goodman at the Aberdeen Test Center with promising results. This study seeks to build on this previous work by producing depth of penetration and perforation experiments using non-deforming projectiles into a similar cellular concrete for validation of the fit HJC model. Depth of penetration experiments were conducted by firing into a 305 mm thick panel over a velocity range of 200–800 m/s with the strike velocity and depth of penetration recorded for each experiment. Perforation experiments were conducted over a range of 200–800 m/s against panels with thicknesses of 38 mm, 76 mm, and 114 mm with the strike velocity, residual velocity, and crater characteristics recorded for each experiment. 2D numerical simulations were conducted for each experiment and the results were compared for initial model validation, but additional experimental testing and simulation is required. There is error between the experimental and numerical results and a sensitivity analysis should be conducted to determine where additional testing is appropriate to improve the model’s correlation with experimental results.

Abstract:
Water flow in dams is commonly regulated using Tainter or miter gates, which are extensively employed in the navigation network of locks and dams managed by the United States Army Corps of Engineers (USACE). Tainter gates are well known for their effectiveness in managing the flow of water through dam spillways. Post-tensioned Tainter gate anchorages are widely utilized in numerous dams across the nation, particularly within the Mississippi Valley Division (MVD), the Great Lakes and Rivers Division (LRD), the Southwestern Division (SWD), and the Northwestern Division (NWD). Between 2010 and 2017, ten dams underwent testing, revealing that eight of them had failed rods. Out of the 5,371 greased trunnion anchor rods tested, 22 were found to be broken, and 6 had slipped gripping hardware. While the overall failure rate might appear low, a detailed analysis shows that individual anchorage failure rates ranged from 2 percent to 29 percent, potentially affecting anchorage capacity and performance. Apart from the trunnion rods that failed due to breaking or slipped connections, 278 rods (202 on Markland Dam and 76 on Greenup Dam) exhibited significant cantilever bending or corrosion, conditions that can contribute to anchor rod failure. This study aims to establish experimental and numerical methods for posttensioned anchorages with different rod configurations. Laboratory tests on scaled anchorages, featuring a concrete trunnion girder with nine high-strength post-tensioning rods, were conducted. Finite element (FE) analyses were validated using experimental data, replicating various trunnion rod failure scenarios. The FE results accurately predicted load changes on each rod under different loads and de-tensioning configurations. The findings from this research provide valuable insights into anchor rod failure rates, which can assist district engineers in assessing the current condition of anchor rods and planning proactive maintenance and remediation strategies.

Abstract:
The US Army Corps of Engineers (USACE) owns, maintains and operates several hundred locks and dams across the United States. A large portion of these structures have met or exceeded their design life, therefore the need to perform detailed inspections regularly has become increasingly important. Some of the challenges for inspection personnel are the hazardous conditions associated with entering dam outlet works, and the need to conduct the inspection within a short time frame so that the dam can resume normal operations and maintain downstream water levels. These subterranean conduits are classified as confined spaces and can be several hundred meters long, have flowing water, and in some instances have toxic gases present. The USACE Engineer Research and Development Center (ERDC) has developed an unmanned amphibious vehicle, called DamBot™, to enter these outlet works with a sensor suite and perform first-look inspections of the conduit and closure gates. In order to carry out these inspections, DamBot™ is equipped with cameras and LiDARs to capture 360 degrees situational awareness around the platform, and a five-meter robotic arm with nine degrees of freedom to perform up close inspection of closure gates, which can be over six meters tall. Additionally, the DamBot™ is able to capture data of the entire conduit during inspections, collecting a dataset that provides a comprehensive picture of the infrastructure. DamBot™ uses techniques such as simultaneous localization and mapping (SLAM) to assure positional accuracy of data collection in these GPS denied environments. These datasets can be post-processed into 3D models and can be used for structural health monitoring by way of change detection when compared with previous inspections. DamBot™ has been successfully demonstrated at several active USACE projects, and this paper will detail the specifications of the system and discuss the results of field demonstrations, lessons learned, and future improvements to the system.

Abstract:
Abstract Currently, the system of locks and dams within the United States operate where each system has a different component and needs different parts to complete the routine maintenance checks and procedures. Having unique components and parts for each lock and dam system drastically increases the costs required for the United States Army Corps of Engineers (USACE) to operate and maintain these locks and dams. One way to reduce these costs is to work towards and recommend standardized components for a lock and dam system. This process, especially for construction projects, is vital because it allows for simplification in the build and production stages of a project as well as life cycle maintenance. Understanding hydraulic design for the inflow and outflow of a lock system was an important consideration for this design project. Reducing hawser forces while maximizing the efficiency of the filling and emptying process is the overall goal for the design. To minimize hawser forces, mitigating the effects of hydrodynamic and hydrostatic forces is essential. This research also strives to gain additional understanding of the dynamic, turbulent nature of water in a lock and dam system. In the Emsworth Lock and Dam system, the top of rock for the riverbed is significantly higher than normal presenting unique challenges for modeling and simulation, as well as physical model construction. Critical to the design of a physical model is the determination of an adequate scaling factor that will not significantly affect the natural hydraulic processes within the system. As such, it is essential that appropriate theories are applied to remain consistent with proven methods of hydraulic scaling. Before selecting a scaling ratio, determining space limitations and a conceptual design of the model was necessary. This assisted in visualizing the model in the available spaces to ensure the design and manufacturing plan was realistic. The model contains three components: a main lock chamber, a higher elevation water reservoir, and a lower elevation water reservoir. The component that is most controlling to the design is the main lock chamber; this component cannot be altered in any way to meet the requirements of the floor space because any modifications would affect the results of the hawser force testing, and the model would not appropriately match reality. The physical model will be verified using the Froude equation — an equation that drives performance of models that are dependent on gravity. As such, when conducting any inflow or outflow of the water in the system, it is essential that the velocity is controlled such that the Froude value is consistent with that of the actual Emsworth Lock and Dam. The model must match a Froude number of 0.052 to effectively represent reality.

Abstract:
This US Army Corps of Engineers (USACE) special report prepared by the US Army Engineer Research and Development Center, Coastal and Hydraulics Laboratory, provides an overview of the current state of practice for nearshore nourishment with dredged sediment. This special report was completed with responses and input from professionals across the dredging and placement teams from each of the USACE Coastal and Great Lakes districts, providing comprehensive overviews of the decision trees these districts utilize in the placement of their dredged sediment. This report describes the general practice of nearshore nourishment, the impediments and concerns faced by nearshore nourishment projects, and the practical methods utilized by the Coastal and Great Lakes districts for their nearshore nourishment projects. Understanding the current state of practice, along with the general and specific impediments the districts face, enables further research in and development of best practices for use across the USACE and better communication of the practice to other stakeholders.

Full text
Abstract:
Given the reported extent of microplastics in the aquatic environment, environmentally relevant exposure information for sediments dredged by the US Army Corps of Engineers will lend context to the risks posed by this contaminant during dredging. We measured the occurrence, abundance, and polymer composition of microplastics in sediments collected from nine dredged waterways and two non-dredged reference areas. The number of particles in sediment samples ranged from 162 to 6110 particles/kg dry wt., with a mean of 1636 particles/kg dry wt. Fragments were the most prevalent shape observed among the 11 study sites (100% frequency of occurrence), followed by fibers (81%), spheres (75%), foams (38%) and films (34%). Based on analyses of chemical composition of the particles using Fourier transform infrared spectroscopy, polyethylene:propylene was the most common polymer type observed. Consistent with results presented by other investigators microplastic concentrations and polymer types in bottom sediments in this study were also aligned with the most widely used plastics worldwide.
