Flexible Pipeline Increases Ship Channel Dredging Research. Volume 5, Number 4. December 2002. Flexible Pipeline Increases Ship Channel Safety for Dustpan Dredge Operations During Marsh Creation (Part 2) DEC 2002 11 pages
Authors:  Timothy L. Welp; ENGINEER RESEARCH AND DEVELOPMENT CENTER VICKSBURG MS COASTAL AND HYDRAULICSLAB
The full text of this report is available for sale.MOVE OUT OF THE WAY OF TRAFFIC. Hopper dredges move dredged material out of the channel and redeposit it somewhere else in the waterway. There is no beneficial use of the dredged material, unless it is handled again at additional cost to get it out of the waterway. Hopper dredges can use direct pump-out to place material in adjacent marsh but have never been used for beneficial use projects at ...


Evaluation and Proposed Refinement of the Sampling Design for the Long Term Resource Monitoring Program's Fish Component OCT 2002 38 pages
Authors:  Brian S. Ickes; Randy W. Burkhardt; GEOLOGICAL SURVEY LA CROSSE WI UPPER MIDWEST ENVIRONMENTAL SCIENCES CENTER
The full text of this report is available for sale.Environmental monitoring programs are frequently designed to track changes in key physical, chemical, and biological features of an ecosystem. As such, these programs provide critical information for detecting changes in system state, investigating causal mechanisms of the observed changes, and making resource management decisions. Because monitoring programs require significant investments of time, money, and human resources to implement and maintain, periodic evaluations of monitoring programs are necessary to determine if ...
