The U.S. Army Corps of Engineers (USACE), Honolulu District (POH) is responsible for the operation and maintenance of 26 navigation projects within the State of Hawaii and the U.S. Pacific territories. The majority of these deep-draft and small-boat harbors include breakwaters that are consistently exposed to a substantial and varied Pacific Ocean wave climate, requiring POH to maintain a rigorous structure condition inspection program to ensure safe and efficient operations at all of its navigation projects. As part of its constant efforts to improve the quality and efficiency of this inspection program, POH has joined with the USACE Cold Regions Research and Engineering Laboratory (CRREL) Remote Sensing and GIS Center of Expertise to utilize an Unmanned LiDAR Scanning (ULS) system to collect LiDAR (Light Detection and Ranging) spatial data and co-registered imagery of breakwaters at Hilo Deep Draft Harbor on the island of Hawaii, and Kaumalapau Deep Draft Harbor on the island of Lanai.

AbstractThe U.S. Army Corps of Engineers (Corps) is a project-oriented agency with multiple national missions under its Civil Works program including navigation, hydropower, flood risk management, ecosystem restoration, water supply, regulatory authority for wetlands and U.S. waters, recreation, and disaster preparedness and response. The Corps ocean and coastal activities revolve around the design, construction, and maintenance of specific projects such as channel dredging, coastal protection, beach nourishment, and harbor construction, all requiring research, modeling, and observations. Several Corps activities contribute ocean observations to the Integrated Ocean Observing System (IOOS®) and have requirements for existing or planned IOOS observations. Collected observations include long-term coastal wave climate, water levels, and coastal mapping data information. These provide project-specific and regional data that are used to develop and verify numerical models which are extensively used in project design and to evaluate project costs, benefits, and associated risk. An overview of the Corps coastal activities, data collection, and modeling programs is provided along with information regarding how IOOS coastal and ocean data are being used by the Corps.

The U.S

The status and the performance of the Harbor Maintenance Trust Fund (HMTF) are evaluated. The harbor maintenance tax (HMT) and HMTF were established by Title XIV of the Water Resources Development Act of 1986. The HMT is applied as a 0.125% ad valorem fee on the value of commercial cargo loaded or unloaded on vessels using federally maintained harbor projects. The HMTF is authorized to be used to recover 100% of the U.S. Army Corps of Engineers eligible operation and maintenance (O&M) expenditures for commercial navigation, along with 100% of the O&M cost of the St. Lawrence Seaway by the St. Lawrence Seaway Development Corporation, certain costs of the National Oceanic and Atmospheric Administration, and costs to administer the HMTF. The U.S. Supreme Court found that the HMT violated the export clause of the U.S. Constitution; as a result, the U.S. Customs Service halted HMT collections on U.S. exports in fiscal year 1998. However, the revenue stream from HMT collections on imports, domestic shipments, passengers, foreign trade zone cargo, and interest earnings should be sufficient to recover eligible expenditures for the foreseeable future.

An evaluation of extreme wave climate was made for Keahole Point, Hawaii. This evaluation was based on three separate sources of wave data and five methods of statistical evaluations. The three sources of data include (1) wave hindcasts data of 10 severe storms between 1947- 1961 by Marine Advisors (1963), (2) wave hindcast data of 11 severe storms between 1947-1965 by U.S. Army Corps of Engineers, Honolulu District, and (3) shipboard wave observations of the U.S. Navy reports. Figure 5 shows SSMO area No. 1 for south and southwest of the islands and SSMO areas Nos. 2 and 3 for north of the islands. The five methods of statistical extrapolations for extreme events include: (1) Gumbel's (1958) first asymptotic distribution, (2) Weibull distribution (1961), and (3,4,&5) semilog, log normal and normal distributions. The three most widely used distribution functions are: (1) Gumbel's (1958), (2) log normal (see Jasper, 1956), and (3) Weibull (1961), given in order as to the author's preference. The statistical extrapolations for Keahole Point, Hawaii, are given in Table 9 and Figure 9. Only Gumbel's (1958) distribution was applied to the north shore as shown in Table 8. Based on Gumbel's distribution function, the results of the wave hindcasts statistics on the average (50 year recurrence interval) indicate that (1) the Marine Advisors (1963) wave hindcasts are about 25 percent higher than the U.S. Army Corps of Engineers wave hindcasts and (2) the U.S. Navy SSMO observations and the U.S. Army Corps of Engineers wave hindcasts are in closest agreement. Shipboard wave observations have always been subjected to questions. However, various authors have correlated instrumentally measured and observed wave observations. A summary of these correlations are given in Table 6. No correction was made to the statistical analysis of the SSMO data.

The U.S. Army Engineer Research and Development Center (ERDC) executes inspection programs as part of the U.S. Army Transportation Infrastructure Program (ATIP). These inspection, monitoring and assessment programs include airfields, bridges, dams, railroads, waterfront facilities and ranges. To date, the process for these inspection programs has been manually intensive, time consuming and difficult to scale. The US Army Corps is bringing digital business and spatial data collection methods to its inspection program for the military’s railroad infrastructure. By combining GPS and GIS technologies into a mobile data collection solution, added efficiency and data quality has been brought to the field inspection workflow. This modernization effort also results in streamlined data processing and reporting. These improved processes will lead to higher quality data, better analysis of the new richer data content and better decisions made by the end users and stakeholders.

The Coastal Engineering Research Center at Fort Belvoir, Virginia, is responsible for research that supports the U.S. Army Corps of Engineers' Civil Works program. This research involves coastal navigation, channel design and maintenance, storm flooding, shore erosion control, and coastal ecology. The ecology research is focused on two major areas: (1) use of coastal vegetation for engineering purposes and (2) effects of coastal engineering activities on the biological environment. The objectives and accomplishments of the ecology research are discussed and specific examples of field guidance are presented.
