Effect of Depth on Dredging Frequency. Report 1. Survey of District Offices.
Abstract
The overall objective of this investigation was to evaluate the effectiveness of advance maintenance dredging (overdepth dredging) in reducing dredging frequency and/or costs in the maintenance of coastal and inland channels and harbors and to establish necessary guidelines for governing the practice. This report, the first of a series, defines the state of the art and presents the results of a survey of U. S. Army Engineer Corps district offices to determine the extent of the usage of advance maintenance dredging. Thirty-five Corps district offices and two division offices (no districts within the division) participated in the survey. The districts are classified as either coastal or inland. Coastal districts are those which include a part of the coastline of the Atlantic or Pacific Ocean of the Gulf of Mexico. Inland districts are those which do not include any of these coastlines within their boundaries. The results of the survey indicate that advance maintenance dredging is practiced on many projects in the coastal districts, particularly those along the southeast Atlantic and Gulf coasts, while it is sparingly practiced (beyond the current dredging season) in the inland districts.
