  • PUBLICATION NOTICE: Contribution of Two Eroding Banks to Multipurpose Pool Sedimentation at a Midwestern Reservoir

    Abstract: This US Army Corps of Engineers (USACE) National Regional Sediment Management Technical Note (RSM-TN) documents the sediment contribution of two eroding banks to multipurpose pool sedimentation at Kanopolis Lake, KS. The analysis is based on a 2009 LIDAR and an August 2019 unmanned aircraft systems (UAS)-based structure from motion survey.
  • PUBLICATION NOTICE: Isarithmic mapping of radio-frequency noise in the urban environment

    Abstract: Radio-frequency (RF) background noise is a spatially-varying and critical parameter for predicting radio communication system and electromagnetic sensor performance in urban environments. Previous studies have measured urban RF noise at fixed, representative locations. The Cold Regions Research and Engineering Laboratory (CRREL) has developed a tunable system for conducting mobile RF noise measurements in the VHF and UHF and shown that urban RF noise characteristics vary significantly and repeatably at a scale of tens of meters (Haedrich & Breton, 2019). CRREL also found high-powered regions in Boston, MA that are persistent over time. However, since previous studies conducted stationary measurements or measurements along linear transects, little is known about the 2-dimensional topography of urban noise and the spatial distribution and characteristics of these high-powered regions. In this paper, we present the results of a dense, block-grid survey of downtown Boston, MA at 142 and 246.5 MHz with measurements taken every meter along each street. We present isarithmic maps of median noise power and describe the spatial distribution, shape and other characteristics of the high-powered regions. We compare the rate of noise power decay around high-powered regions to losses predicted by a power law model of path loss.
  • PUBLICATION NOTICE: Enhancing Army Energy Culture with Behavioral Approaches

    Abstract: Facility energy efficiency efforts too often underperform because of people’s choices and actions in their use of technology. Recognizing this challenge, Army energy guidance calls for establishing an informed energy-conscious culture of stewardship to meet mission resilience requirements. However, the details for implementing that guidance have not been established. This report provides two primary products to address these needs: (1) a Human-Centered Efficiency Process (HCEP), which is a coordinated nine-step process to use best practices in energy behavior, and (2) an outline of a strategy to build a culture of efficiency. The practical HCEP is synthesized from energy management, change management, and Army processes (After Action Report [AAR] and Commander’s Intent), as well as insights from federal personnel. It is built around an organizational framework and a continuous improvement process that systematically enables people to use technology effectively and efficiently. The culture strategy consists of a method of assessing the current status of the Army’s energy culture; a vision of a desired end state; and a path toward change.
  • PUBLICATION NOTICE: Water Security Scenarios: Planning for Installation Water Disruptions

    Abstract: The Army’s critical missions are at risk from interruption of water supplies. Sufficient amounts of high- quality potable water are a resource without substitute. The Army’s Installation Energy and Water Security Policy establishes requirements for installations to sustain critical mission capabilities and to mitigate risks posed by energy and water disruptions that affect installations; this includes coordinating vulnerability and risk assessments of potential disruptions and implementing adequate responses to mitigate identified risks. Resilient installations will develop storage capacity to forestall water shortages and will also have short- and long-term plans to help the installation recover from events and forestall progressing to more severe deficits. This project supports compliance with the water security policy by exploring the range of conditions and responses possible across installations. Multiple scenarios were developed to explore how a 14-day interruption in water supply might affect an installation and to provide preliminary guidance to help installations develop strategies to address water disruptions to critical missions drawing from existing processes used in mission assurance. Researchers investigated types of installations and classes of scenarios most relevant to installation water security planning and explored several scenarios to provide a framework to helps installations advance their water resilience and security planning.
  • PUBLICATION NOTICE: Seasonal Effects on Vehicle Mobility: High-Latitude Case Study

    Abstract: Seasonality plays a key role in altering the terrain of many military operating environments. Since seasonality has such a large impact on the terrain, it needs to be properly accounted for in vehicle dynamics models. This work outlines a variety of static and dynamic seasonal terrain conditions and their impacts on vehicle mobility in an austere region of Europe. Overall the vehicles performed the best in the dry season condition. The thaw season condition had the most drastic impact on mobility with all but the heavy tracked vehicle being almost completely NOGO in the region. Overall, the heavy tracked vehicle had the best performance in all terrain conditions. These results highlight the importance of incorporating seasonal impacts on terrain into NRMM or any vehicle dynamics model. Future work will focus on collecting more data to improve the empirical relationships between vehicles and seasonal terrain conditions, thereby allowing for more accurate speed predictions.

  • PUBLICATION NOTICE: Insights: An Update of the USACE Data Strategy Initiative; November 2019 Edition

    Abstract: The Data25 strategy was advanced in FY19 by the U.S. Army Corps of Engineers’ Chief Information Officer (USACE CIO) by funding pilots to show the power of data analytics on real USACE operations. This report details pilots that were conducted in three of USACEs Business Lines; Dredging, Hydropower, and Military Construction. The purposes for each of these pilots are listed below. 1. Enterprise value: Demonstrates the power of data analytics and its ability to generate business value by improving decision-making across the organization. 2. Technology value: Helps the CIO understand how cloud technology could support the overall data strategy. 3. Business value: Provides examples of data analytics in action. This view helps the Business Lines, Divisions, and Districts understand what it takes to supplement decision-making with insights generated from data. The main purpose of the pilots was to provide a glimpse of what could be gained from data analytics. From the initial business questions, the pilot Business Lines are seeking to use data to improve decisions through the automation of business processes, more rapid decision cycles, and the layering of previously siloed data on their own to reveal new insights.
  • PUBLICATION NOTICE: Insights: An Update on the USACE Data Strategy Initiative; April 2019 Edition

    Abstract: The U.S. Army Corps of Engineering (USACE) Commanding General, LTG Todd T. Semonite, announced 10 initiatives on May 2018 to improve execution through informed decision-making, enabling lower costs, and world-class engineering results today and tomorrow. Two of the initiatives were geared to transition USACE to data-informed decision-making through the use of data analytics. The first of these two initiatives sought to implement a data strategy that included a doctrine and governance, through creation of a data management plan. The plan implemented tools to aggregate data across the organization and improve reporting. Dr. Cary Butler, USACE Chief Data Scientist, led this effort. The second initiative sought to establish a dedicated USACE Innovations Team to build and recruit a skilled team to act as finders and enablers of innovative, enterprise solutions that enabled USACE to become a digital business. The USACE Chief Information Officer oversaw both initiatives. Because goals and objectives overlapped in many areas and gathered momentum for these initiatives, leaders from both teams came together and decided that showing the business value of data analytics to improve decision making across the Corps should be a top priority. This document was used to report on the progress of the initiatives and give a better understanding of the need for data-informed decisions throughout USACE.
  • PUBLICATION NOTICE: New York/New Jersey Harbor Sedimentation Study: Numerical Modeling of Hydrodynamics and Sediment Transport

    Abstract: The New York/New Jersey Harbor (NYNJH) is a vital economic resource for both the local economy and the entire US economy due to the vast quantity of imports and exports handled by the numerous ports in this waterway. As with most ports, there is a significant, recurring expense associated with dredging the navigation channels to the authorized depths. In an effort to determine the impact of channel enlargements (“the project”) on dredging volumes, a numerical model study was performed. The advantage of a numerical model study is the ability to isolate individual system modifications and associated impacts in terms of dredging volumes. Five years (1985, 1995, 1996, 2011, and 2012) were simulated for both the with- and without-project conditions to determine the impact of the channel deepening on the dredging requirements for a wide range of meteorological conditions including storm events. The numerical model results were analyzed to provide insight into which locations will experience increased/decreased deposition and quantify the amount of increase/decrease for a given channel reach. The model results indicate a relatively minor increase in the total dredge volumes for the NYNJH with the increase being insignificant in comparison to the natural variability in dredge volumes across years.
  • PUBLICATION NOTICE: Fine-Grained Sediment within Olcott Harbor, Eighteenmile Creek, NY

    Abstract: Olcott Harbor, located at the mouth of Eighteenmile Creek and Lake Ontario, and a Great Lake Area of Concern, provides a temporary sink for contaminated, fine-grained sediment transported downstream from the Superfund site near Lockport, NY. The volume of fine-grained sediment currently stored in Olcott Harbor and Eighteenmile Creek is unknown, complicating remediation efforts. The US Army Corps of Engineers (USACE), Buffalo District (LRB), has partnered with the New York State Department of Environmental Conservation to address the mitigation of contaminated sediment accumulating within Eighteenmile Creek. As part of this effort, researchers from the US Army Engineer Research and Development Center (ERDC) collaborated with LRB to delineate fine-grained sediment regions from coarse-grained regions in Olcott Harbor and Eighteenmile Creek via a geophysical survey in July 2017. Where possible, ERDC also estimated the thickness of the fine-grained sediment areas to determine overall fine-sediment volume. Sidescan sonar was used to map the surface transition from the coarser-grained sediment in the outer harbor to the finer-grained sediment in the inner harbor. Chirp sub-bottom profiles successfully imaged the subsurface transition from coarse- to fine-grained sediment in some areas but provided only limited thickness data. This technical note summarizes the field effort, data processing, and final interpretations.
