Chicago Harbor model built at ERDC

(published in the Chicago District, Chicago Breeze, August 2002)

The Engineer Research and Development Center boasts a model that's definitely not your typical wood glue-type. This one, a 3-D, 1:120 physical model built inside one of ERDC's hangars, replicates over 18,000 feet of the Illinois shoreline. The physical model study, sponsored by the Chicago District, will figure out ways to reduce wave heights in the existing harbor. The study will include determining performance of the breakwater structures from past to future and damages to shoreline structures such as Navy Pier and the Jardine Water Treatment Plant.

"High waves can damage boats in the harbor," said Don Wadleigh, Construction-Operations Division. "Damage to boats and other watercraft moored in Monroe and DuSable harbors is also a possibility, as well as damage to the Jardine Water Purification Plant and Navy Pier."

According to Chris Katzenmiller, lead project team member, the model will enable the District to evaluate wave conditions in the harbor from three wave angles with varying wave heights and water levels.

The project, a part of the Chicago Harbor major rehabilitation report, will evaluate the performance of the outer and inner breakwaters during varying storm events. "Wave conditions in the harbor will be studied to determine damages to vessels, and safe operating conditions to vessels," Katzenmiller said. "The performance of the inner breakwaters will determine safe operating conditions for both Monroe and DuSable harbors."

Other project team members include Bill White, Project Management Branch; Mike Fisher, Plan Formulation Section; Tim Kroll, Civil Design Section, and volunteer Charlie Johnson, retired RD coastal engineer. Ray Bottin, research physical scientist, is the lead ERDC study investigator. ERDC has set up a webcam for online views of future model runs. The webcam and more information about the Chicago Harbor model study is available here.

The Chicago District is also planning to rehabilitate the Chicago Harbor Lock, which includes replacing gates, operating equipment and gate controls. A study and report was completed in 2001. The rehabilitation project has been authorized and is awaiting funding.

Looking for Navigation information in your region?

Would you like to find out about Corps navigation projects? Lock and dam statistics? River stage information? Historical navigation data? Dredging and channel maintenance schedules? Navigation studies? Corps Divisions and Districts have Navigation Branch and Civil Works web pages that provide a variety of navigation information specific to areas under their jurisdictions.

Here are a few examples:

  • The Mississippi Valley Division River Stage web page links you to water management information for each of the six Districts under its jurisdiction: St. Paul, Rock Island, St. Louis, Memphis, Vicksburg, and New Orleans. At each of those sites you'll find information such as river stages by basin, historical data, precipitation tables, forecasts, and lock and dam information.
  • The Mobile District Navigation Homepage provides Notices to Navigation Interests, lock maintenance schedules, hydrographic condition survey data, emergency lock closures, navigation charts and maps, and dredging schedules.
  • The Philadelphia District Navigation page furnishes information about its navigation projects, lists the District's navigable waterways, and provides hydrographic survey data for waterways it maintains, along with information about the Corps Dredge McFarland.
  • Get Walla Walla District Lock Data for the Columbia-Snake Rivers Inland Waterway.
  • Find information about new and existing navigation projects in the Great Lakes Region, navigation reports and data, and how to obtain river charts on the Ohio River at the Great Lakes and Ohio River Division Navigation Page.
Other great sites for getting Corps navigation information include the Navigation Information Connection and the Navigation Data Center. These sites and all Corps Division and District navigation-related pages are compiled on the "Related Links" page of the USACE Navigation web site. Find out what navigation is all about in your region!

Navigation Study Interim Report Released

In July 2002, the Corps Rock Island District announced the release of the interim report on the restructured Upper Mississippi River/Illinois Waterway System Navigation Feasibility Study. The Interim Report outlines those navigation improvement and ecosystem restoration measures that will be carried forward for evaluation.

These measures include:

  • Nonstructural measures such as congestion fees and traffic management.
  • Structural measures such as guidewall extensions, lock extensions, and new locks, and Ecosystem restoration measures such as traffic impact prevention and reduction, channel modifications, systemic fish passage and water level management, and backwater, secondary channel, and island rehabilitation.
  • The Waterways Journal, Aug 5, 2002 issue stated that industry advocates applauded the recommendation to advance the cause of lock modernization.
The restructured study and the development of the Interim Report are being accomplished under a new spirit of collaboration among the stakeholders of the Upper Mississippi River and Illinois Waterway System. This Interim Report has been provided to the Corps' Washington, D.C., headquarters and to Congress.

This Interim Report provides a history of past study activities, the purpose of the restructuring, initial plan formulation activities including establishment of goals, objectives and alternatives, and also identifies implementation issues. In addition, the Report contains preliminary conclusions that will be further developed in the feasibility study. The next step in the study is the completion of a Draft Feasibility Report in early 2004.

The Navigation Study Interim Report Executive Summary is available here online.

The complete report is also available here.
