  • Our sincere condolences to the families of Mr. Timothy L. Welp. His pass away is a big loss to the WODA Reservoir Dredging Working Group.

WODA Reservoir Dredging Working Group (China Area) Symposium held on 18-09-2021

On Sep. 18th, the Reservoir Dredging Symposium was held in Shanghai, in the campus of Engineering Research Center of Dredging. Working group members from China, together with 20 invited (by ChiDA) experts on the topic, gathered together, for the first time, face-to-face since the pandemic breakout, to discuss the sedimentation problem in reservoirs.

Dr. Xiuhan Chen first introduced the progress and focus of the WG, and then Dr. Huiqun Cao (Changjiang Institute of Science) introduced the survey work on the sediments near the Three Gorges Dam. Shuai Jiang (WG member) presented the dredging projects in several small reservoirs in the southwest of China. The symposium then focused on the outlines of WODA Reservoir Dredging Guideline. Writing tasks were distributed among the members.

A great news from the symposium: Five new members joined the WODA ResDred WG via the recommendation of ChiDA (China Dredging Association). We warmly welcome the following five new members from EADA.

WODA Reservoir Dredging Working Group Full Group Progress Meeting held on 30-09-2021

A full group progress meeting was held on Sep. 30th. On the meeting it is announced that Dr. David Middlemiss, will work as the secretary for Subgroup 3. Each subgroup has provided their updates for the recent four months work. All the writing tasks have been assigned. The plan for the coming period is: by Oct. 31st, all the members should submit what have already been accomplished. Polite and Xiuhan will check the consistency and overlap among the contents. Discussion will be held with all the subgroup leaders and secretaries, to form a logical and well-organized outline.

Another important agenda of the meeting was the presentation given by Dr. Nikolaos Efthymiou, who is an expert managing the global sediment management study for storage reservoirs and RoR hydropower plants which runs under the Hydropower Development Facility of the World Bank. He introduced the latest development on the sediment management software RESCON 2 (REServoir CONservation). The next step would be members of our working group try with the model and provide some feedback's.

 

 

Progress update 03-05-2021

During the past half year, the WODA Reservoir Dredging Working Group (ResDred WG) has made steady progresses. Via a series of discussions, the three subgroups have created their own outlines according to the following three subjects:

  • Subgroup 1: Building Inventory of the main problems regarding reservoir sedimentation
  • Subgroup 2: Characterization of the different types of reservoirs
  • Subgroup 3: Building the inventory of solutions

In April, the three separate outlines are combined into one overall outline, which consists of 25 chapters in total. An overall WG meeting was held on April 30th, where the overall outline has been temporarily approved.

We are also happy to have our new member, Mr. Maarten Molhoek, business development manager of Royal IHC (CEDA), to join the WG as the 40th member.

A preliminary schedule for the WG has been created and displayed as below:

Progress update 30-12-2020

The WODA Reservoir Dredging Working Group (ResDred WG), is established under the supervision of WODA Technical Orientation Committee (TOC). The goal of this working group is to develop dredging based solutions for the sedimentation problems in reservoirs worldwide.

A complete Terms of Reference (TOR) of the WG can be found via the following link:

https://www.westerndredging.org/phocadownload/WODA/WODAWG-Reservoir-Dredging-TOR-20200625.pdf

The working group has held its kick-off meeting on 30-09-2020. Due to the Covid-19 situation, currently all the WG activities are held online.

Fig. 2. Kick-off meeting of WODA ResDred WG on 30-09-2020

Every month the WG will hold an online meeting, where ideas are exchanged and specific topics are presented by our expert members. A Working Group Committee is organizing and managing the work and activities of the WG. The WG committee includes:

• Polite Laboyrie (Chairman)
• Johan Pennekamp (CEDA)
• Cees van Rhee (CEDA)
• David Padman (EADA)
• Xianguo Qian (EADA)
• Marcel Hermans (WEDA)
• Tim Randle (WEDA)
• Xiuhan Chen (General Secretary)

We are very proud of the status that, up to now, the WODA ResDred WG consists of 39 members coming from all the three sister associations under the WODA umbrella: the Central Dredging Association (CEDA), the Eastern Dredging Association (EADA) and the Western Dredging Association (WEDA).

In the first phase of the WG work (2020-09 ~ 2021-05), the WG is divided into the following three subgroups, and each subgroup will establish the knowledge base of its own topic:

  • Subgroup 1: Building Inventory of the main problems regarding reservoir sedimentation
  • Subgroup 2: Characterization of the different types of reservoirs
  • Subgroup 3: Building the inventory of solutions

The three subgroups will work on the topics of each own. It is expected that the preliminary research results of the three subgroups will be combined on Jun. 2021.

 

INFOMATION & CONTACTS

The WG will constantly provide updates on our research results via the WODA website (Reservoir Dredging – World Organization of Dredging Associations (woda.org)), the conferences of dredging associations, WODCON, dredging-relevant magazines, and scientific journals.

If you have questions or you are interested in joining us, you could either contact your regional dredging association (CEDA, EADA, WEDA) or send an email to the WG secretary-general Xiuhan Chen: X.Chen-1@TUDelft.NL.
