This is the modified, April 2014, version of a report that was originally delivered to the Army Corp of Engineers, Baltimore District in April 2013. The report was modified in April 2014 to accommodate edits requested by USACE headquarters. A large section of the original 2013 report was reorganized into a new Appendix (D), and summary text from several of the original appendices was copied into the report. The overall content of the two reports is essentially the same. The original, 2013 version is available in ICPRB publications. The final, eleven appendices are available for download.
