Upcoming WEDA Membership Change
Based upon the membership feedback received, we are in the process of upgrading our systems and changing the membership period from the current January 1st to December 31st cycle to an individual membership tracking system that will allow all memberships to be active for one full year. This way, your WEDA memberships will be valid for 365 days from the date you join or renew your membership. We’ll share more on this in the next few months.
If your WEDA membership is not currently active, CLICK HERE to renew today. If you’re uncertain of the status of your membership, contact us at and we’ll be happy to assist you.

As Chairman of the WEDA Latin America Committee, I would like to salute Paulo Rodriguez for his many years of service as President of the Brazil Chapter and for all the progress he made in raising public awareness of WEDA throughout his home country.  
Jan Van Den
I am equally excited to welcome Jan Van Den Driessche as our new leader of what is now the South America Chapter.   As Paulo brought his wealth of knowledge and experience in the Brazilian dredging market to WEDA, Mr. Van Den Driessche will do the same and on a larger scale, applying his 22 years of experience at Jan de Nul as Senior Business Development Manager of Latin America, the Caribbean, Spain and Portugal.  With the other members of the WEDA LATIN Committee, I look forward to collaborating with Mr. Van Den Driessche to drive WEDA’s mission throughout South America and to host a chapter meeting in Buenos Aires in 2018.  Welcome aboard, Jan. WEDA is a non-profit organization which is governed by a Board of Directors. Each month we list the profile of one of WEDA’s Directors. We hope this will help everyone get more familiar with the people behind our organization, make it easier for you to reach out to any of them when you want to, and in general to enhance our connections within WEDA. To view Jan’s CV, CLICK HERE.

Researchers from the US Army Engineer Research and Development Center developed a website dedicated to the practice of thin layer placement of dredged material, which is sponsored by the Dredging Operations Technical Support (DOTS) Program managed by Dr. Burton Suedel. The website consolidates all resources and information available relevant to thin layer placement. The purpose of this site is to provide a source of information, knowledge, and experience on thin layer placement of sediment or dredged material in aquatic environments. Our overarching goal is to share resources that will help promote successful thin layer placement projects.
Thin layer placement is broadly defined as the “purposeful placement” of dredged material with layer thickness ranging from a few centimeters to some fraction of a meter, as defined by the goals and requirements of the selected site. Thin layer placement can be used to meet a number of site- and project-specific goals, including efficient and sustainable sediment management, restoring local/regional sediment processes, sediment remediation, and habitat creation.
The website addresses a lack of technical guidance specific to thin layer placement by gathering relevant literature, as well as reports and data pertaining to undocumented case studies. Resources from other technical areas containing potentially relevant information have also been included. For example, the design and placement procedures for sediment capping, while developed for remediation projects, may be adaptable to thin layer placement.
This site is organized to facilitate sharing information about thin layer placement related to planning, designing, engineering, and operating thin layer placement projects in the full range of contexts where this technique would be applicable and useful. To this end, we invite visitors to this site to share their project reports and other documents related to thin layer placement, so that we can include them in this on-line library of resources and make them available to the broad technical community interested in this operational practice. A map-based portal is nearing completion that will allow users to input project information, locate projects and source materials on a map, access hydrodynamic and sediment data from other projects, locate navigation channels and dredged material placement areas, pull up dredging schedules, and download reports and data of interest. All of these tools are intended to facilitate the application of thin layer placement and, ultimately, to provide the basis for developing structured guidance for the practice of thin layer placement.
To access the website please click on the following link: . For additional information and submission of case studies for consideration please contact Ms. Damarys Acevedo-Mackey, PE (email:, phone: 601-634-4845).
A reliable non-nuclear density measurement instrument has been on the wishlist of dredging managers for as long as nuclear densitometers have been in existence. Nuclear meters have been the standard due to their accuracy and reliability. But, managing the administrative requirements of the nuclear sources is an endless and cumbersome process that all dredging companies would love to see go away.
There have been several attempts at building non-nuclear density instruments that can survive the dredging environment over the years, but none have proven reliable and accurate. However, during the last couple years there appears to have been a breakthrough. One such source is from ITS. Based on electrical resistance tomography, the ITS (Industrial Tomography Systems) DENS-ITOMETER system can provide density measurements regardless of flow regime while simultaneously measuring the concentration of materials which are naturally buoyant.

After installation, the system is easily calibrated to deliver a concentration measurement based on the volume of solids flowing through the pipe. ITS software then converts the gathered concentration data to provide real-time volumetric imagery of the slurry’s flow regime and solid contents. The instrument is supplied as a hard-wearing pipe based sensor, with a standard IP67 instrument enclosure. Initial customer results have yielded an accuracy of >95% and validated the systems robustness, with over 25,000 operating hours needed before servicing is required.

New installations include an integrated modem allowing remote support. Density information can also be presented over a local area network. For more information contact
