      <title>Prediction of Storm Surges and Wind Waves in Mobile Bay, AL</title>
      <link>https://trid.trb.org/View/2228357</link>
      <description><![CDATA[The study utilizes two state-of-the-art computer models to predict storm surges and surface waves in the Mobile Bay estuary, Alabama. Both numerical models have the capability of resolving the complex geometry and moving boundaries associated with coastal flooding. Two storm events are simulated for a period of 16 days in September 2002 when Tropical Storms Hanna and Isidore passed through the region. Good agreement between the modeled and measured water levels at five tide gauging stations in Mobile Bay has been found. The surge model (ADCIRC) shows that the majority of Dauphin Island and the south stretch of AL Highway 193 were flooded by TS Isidore. Strong currents over 1 m/s are predicted by the hydrodynamic model. The third-generation wind wave model (SWAN) reveals the spatial distributions of wave heights and wave periods in the Mobile Bay estuary. This enables us to estimate the elevated sea level owing to the breaking of surface waves on the inundated barrier island and roadways. The methodology of coupling the surge and wave models can be used to improve the design of coastal infrastructure and to facilitate hurricane emergency management.]]></description>

      <title>Planning for the Upper Mobile Bay Beneficial Use Wetland Creation Site</title>
      <link>https://trid.trb.org/View/2023498</link>
      <description><![CDATA[The Alabama State Port Authority (ASPA) currently has high annual dredge maintenance costs due to limited dredge management options. The ASPA 2018 master plan identified that an improved dredged material management program could result in millions of dollars of annual savings. The Upper Mobile Bay Beneficial Use Wetland Creation Site project represents a positive paradigm shift in ASPA’s dredge material management approach that results in environmental stewardship and economic benefits for the port. ASPA was directly impacted economically by the Deepwater Horizon oil spill in 2010. Resulting civil penalties are funding the Resources and Ecosystems Sustainability, Tourist Opportunities and Revived Economies of the Gulf Coast States Act (RESTORE Act), which established the Gulf Coast Ecosystem Restoration Council (Council) to implement a comprehensive plan for economic and environmental recovery. Wetland creation through the beneficial use of dredged sediments simultaneously restores ecosystems while bolstering the Gulf Coast’s economy.]]></description>

      <title>Sea Level Rise and Storm Surge Impacts on a Coastal Bridge: I-10 Bayway, Mobile Bay, Alabama</title>
      <link>https://trid.trb.org/View/1501848</link>
      <description><![CDATA[This is one of nine engineering case studies conducted under the Transportation Engineering Approaches to Climate Resiliency (TEACR) Project. This case study focused on the vulnerability of a coastal bridge to sea level rise and storm surge. This assessment investigates potential structural and hydraulic engineering adaptations to increase the resilience of a coastal bridge to extreme events in rising sea levels. The assessment focuses on the I-10 Bridge, which crosses northern Mobile Bay, Alabama (known locally as “The Bayway”). The seven-mile long bridge crosses open bay waters, coastal marshes, and tidal rivers. The assessment found that the existing I-10 Bridge is vulnerable and would be destroyed by waves on storm surge under a scenario in which a storm like Hurricane Katrina directly hits Mobile in the future with 75 cm of sea level rise. Loss of the bridge could directly cost primary users $1,130,800 per day. Retrofit adaptations which strengthen the connections between the superstructure (the decks) and substructure could be designed to avoid the primary, historical damage mechanism (separation of the decks from substructure). However, such adaptations alone will likely end in the destruction of the bridge due to other failure mechanisms (deck-girder damage due to negative bending and pile damage) slightly later in the storm. The only adaptation which will protect the bridge is increasing its elevation - perhaps in combination with some of the other structural modification adaptations considered.]]></description>

      <title>Cost Effective Dredging in Mobile Bay: Possibilities for Sustainable Dredged Material Management</title>
      <link>https://trid.trb.org/View/1241040</link>
      <description><![CDATA[This paper describes a study performed at the University of South Alabama to determine the cost-effective method of dredging in Mobile Bay and to explore the possibility of utilizing the dredged materials in an environmentally sustainable way. Historical cost and working time data for hopper dredging and pipeline dredging for Mobile Bay in Alabama from 1991 to present were obtained from the Mobile District United States Army Corps of Engineers. For comparison, dredging data for Bayou Casotte in Mississippi were also obtained. An analysis of data showed that there was no significant difference in unit costs for pipeline and hopper dredging in Mobile Bay. However, further analysis showed that pipeline dredging was able to output more dredged material daily than hopper dredging. The disposal methods of dredging operations were taken into consideration while interpreting the results. Although the cost was similar, the extended distance that a hopper dredge has to travel to dispose of dredged sediment seems to make pipeline dredging more desirable for Mobile Bay and its channel maintenance needs. Moreover, if future shoreline restoration projects are initiated, pipeline dredging is expected to become the more desirable maintenance dredging method to keep up with the demand for material for shoreline re-nourishment activities. In addition to shoreline re-nourishment, the paper discusses several other possibilities of sustainable utilization of dredged materials, including using desalinated dredged sediments on agricultural lands in Alabama and elsewhere.]]></description>

      <title>STUDY COMPUTES BENEFIT OF TENN-TOM BOATS</title>
      <link>https://trid.trb.org/View/709743</link>
      <description><![CDATA[This article describes studies focusing on the economic impact of pleasure boat usage of the Tennessee-Tombigbee Waterway (the Tenn-Tom) that connects the Upper Midwest to the Gulf of Mexico. Large pleasure boats were found to add more than $5.5 million to the local economy through spending as their occupants sail along the waterway, which is the shortest, safest water route between mid-America and the Gulf Coast. Many of the trips are seasonal, as residents near the Great Lakes and other northern places travel to Florida for the winter. These seasonal travelers were the basis for the $5.5 million figure.]]></description>

      <title>TOWED RESISTANCE TRIALS IN ICE OF THE USCGC MOBILE BAY (WTGB 103): FINAL REPORT, AUGUST, 1987</title>
      <link>https://trid.trb.org/View/394412</link>
      <description><![CDATA[An extensive series of towed resistance tests and corresponding self-propulsion tests were carried out for the USCG MOBILE BAY. The trials provided full-scale verification of icebreaker resistance. Testing was carried out in Lake Michigan at various speeds and in a range of thicknesses of level, unbroken ice. Thrust, torque, propeller RPM, speed and towing pull were recorded. Analysis of the results included examination of established ice resistance formulations to assess the influence of different test parameters. Trends in thrust deduction, wake fraction and propulsive efficiency components were derived and compared to model test results for the 140 ft. WTGB class hull form.]]></description>

      <title>FULL-SCALE TOWED RESISTANCE TRIALS OF THE USCGC MOBILE BAY IN UNIFORM LEVEL ICE</title>
      <link>https://trid.trb.org/View/400430</link>
      <description><![CDATA[In February of 1986 an extensive series of ice trials was carried out on the USCGC MOBILE BAY in Green Bay. These trials included the first towed resistance tests of an icebreaker ever performed, and marked a new level in the prediction of icebreaker resistance and propulsive performance.  The background section of this paper reviews the historical development of techniques for evaluating the resistance and propulsion of icebreakers. It provides parallels to open-water predictions, comparing the current trials with those of GREYHOUND and LUCY ASHTON. The description of trials includes discussions related to the selection of vessels and locations, as well as preparation of test and monitoring instrumentation. The primary emphasis is on the procedures employed to tow MOBILE BAY by a 5-cm (2 in.) steel towline from the USCGC MACKINAW through unbroken level ice. Results are provided for all towed and self- propulsion tests. This section also includes a discussion of the quality of the data collected. During the trials, 17 towed resistance tests and 31 self-propulsion tests were performed. The analysis section of the paper provides insight into the problems associated with predictions of icebreaker performance. This unprecedented dataset has allowed rigorous examination of such critical propulsion parameters as thrust deductions, effective wake, and relative rotative efficiency with some surprising results. Analysis of the resistance data alone is reported, covering the efficacy of nondimensional analysis techniques and existing empirical resistance prediction forms. The data are compared with model test results at various scales and using various ice modeling materials to provide a definitive evaluation of the accuracy of ice model tests. The conclusions and recommendations from the parent study are summarized, with special emphasis on guidance for designers of iceworthy ships.]]></description>

      <title>FIBER OPTIC INTERCOMPARTMENT CABLE SERVICE INTEGRITY TEST</title>
      <link>https://trid.trb.org/View/399026</link>
      <description><![CDATA[The Fiber Optic Intercompartment Cable Service (ICCS) aboard the USS MOBILE BAY was monitored during ship shock trials as part of a task to investigate the survivability of fiber optic sensors and communication systems installed on CG-47-class cruisers. Several circuits of the ICCS were monitored in real time during the shock trials to determine any cumulative effects or effects at discrete locations in the circuit. These test circuits passed through multiple compartments, primarily in the lower portions of the hull where typical fiber optic cable plants would be located and where the maximum shock effect would be expected to occur.  All test circuits used fiber optic components planned for use on CG-47-class ships. Results of the tests indicate that fiber optics are a viable method of data transmission aboard Navy surface vessels.]]></description>
