Very interesting post in Linkedin about grass roots, which shows we still have a lt to learn on this topic :  link

Discovery of ancient levee in the Netherlands

Near the town of Vlaardingen, remnants have been found of an ancient construction that probably served as a low levee. The construction was about 1 metre in height, at least 20 metres long, and consisted of a dual construction consisting of wooden piles and braided willow branches, that was subsequently filled with earth.

The levee was probably constructed over 2000 years ago, during the 2nd century BC. As such, it is probably the most ancient levee discovered so far in the Netherlands.

Reflections on the ICOLD LE TC meeting September 2020

The ICOLD Levees Technical Committee (LE TC) 2020 met over the last three days of September for our 2020 meeting. These are some of my personal reflections.

The current restrictions in response to COVID19 were overcome by having a teleconference on each of the days. I think the importance of Levees worldwide was seen by the range of countries that joined the meeting despite the large time differences for some. We were also pleased to Welcome Michael Rogers, the current President of ICOLD, to one of our meetings. Each day had a different theme.

Day 1: On the Monday we considered the Levees situation report. The report is well developed containing information, including a section with detailed information about levees within many countries. The version of the Levee Situation Report tabled at the meeting was approved.

Day 2: The focus for Tuesday was the dams-levees comparison report. Chapter include design, construction and inspections. Draft chapters were considered with feedback for the authors. The report is developing into a useful source and signpost for information and will help learning across dam and levee practitioners.

Day 3: The Wednesday meeting considered general topics. I particularly noted the importance of effective national backing groups to support TC members as the reports are nearing completion. It was also an opportunity for suggestions for future bulletins.

I was again impressed by the importance of levees across the world combined with the knowledge and enthusiasm of those managing them.

Free ICFM webinar on flood events China, JP, USA (26 Aug)

Under the title “The Flood Challenge to Resilience” ICFM will share the experience with (i) major flooding in China that affected/s millions of people and hundreds of river basins; (ii)  flooding in Japan caused by truly extraordinary amounts of rain falling over the island of Kyushu; and (iii) flooding in Michigan (US) that interacted with aging infrastructure and resulted in failure of two dams.

Three highly regarded speakers – Professor Jun XIA, Professor Toshio KOIKE and Dr. Molly FINSTER –  will introduce these topics and set the stage for the discussion by the audience. See the webinar invitation/registration page at www.icfm.world/Webinars.

Building a resilient flood protection system, including to overtopping. Summer 2019: creating openings in an existing railway

History of the project

On the left bank of the south of the Rhône river (in France), between the cities of Tarascon and Arles, a railway embankment has performed for many years as a flood protection structure although it was not a role falling under its owner (the French National Railway company) responsibility. In December 2003, because of breaches in appurtenant embankments, the north of the city of Arles was flooded for many weeks.

Fig. 1: breaches on appurtenant embankments in 2003

In the aftermath of this centennial flood, the State and local authorities have put in place a vast flood prevention plan at the scale of the catchment area, called Plan Rhône, which notably provides for the complete renovation of the levees of the Rhône Delta over 20 years. Among this ambitious program, was decided the creation of a levee resistant to overtopping up to the 100 year flood, parallel to the railway embankment, and the creation of 10 openings (concrete structures) in the railway in order for it to be “hydraulically transparent” (see Fig. 2). This segment of levee and the reinforcement of the rest of the system against all other deterioration and failure mechanisms allows the whole levee system to withstand floods up to the 1000 year with a 50 cm margin (the crest level of the levees not-resistant to overtopping). Floods above the protection level (100 year) will flood the protected area in a controlled way and with many times less water volume and speed than any previous scenario with the same probability (see Fig. 3). A second line levee will prevent the flood going over the new levee to reach the densely inhabited suburbs of Arles.

Summer 2019

During the summer of 2019, over two periods of barely more than 48 hours, five out of the ten opening structures(like the one in figure 4)  were put in place in the railway embankment. The planning of these operations started years in advance, as it involved the disruption of the rail traffic on a major line of train transport for both passengers and goods. The five other ones are being constructed now at a short distance along on the side of the railway embankment and will be put in place during the summer of 2020. During each of these sequences of non-stop operation, the following steps have to be successively completed:

  • Cutting the rails
  • Creating an opening in the embankment (Fig.5),
  • Adding a layer of material to support the structure,
  • Moving the concrete structure in its final place and checking its proper placement (Fig. 6), as well as smaller parts on each side, also prefabricated (Fig. 7),
  • Filling the space between the embankment and the concrete with new embankment and compacting it (Fig. 8)
  • Adding railway ballast
  • Repairing the rail line and setting it to ensure its performance (Fig.9)

The hazard of a flood happening during these crucial phases was considered and measures were taken to minimize the risks, including being able to close the embankment openings in case of a flood not foreseen when the operation started.

The openings are temporarily closed until the new levee is completely built, in order to keep ensuring the current protection level (Fig. 10). Afterwards stilling basins can be added (Fig. 11)

During the Marseille 2021 ICOLD congress, one of the field trips will be organised in this area and the whole complex system will be presented: overtopping resistant levee, opening structures, second line of defence and flood water management.

Fusion of information from geophysical and geotechnical investigations for levee assessment

The identification of levees constitutive materials, as well as the detection of possible interfaces and anomalies, are crucial for site characterization. During investigation campaigns, complementary geophysical and geotechnical methods are usually used. These two sets of methods yield data with very different spatial scales and different levels of incompleteness, uncertainty and inaccuracy. On the one hand, geophysical methods are generally non-intrusive and provide physical information on large volumes of soils but with significant potential uncertainties. These uncertainties are due in particular to the integrative and indirect aspects (relative to the parameters related to failure modes limit state equations) of the methods as well as to the resolution of the inverse problems. On the other hand, geotechnical investigation methods are intrusive and provide more local information but also more accurate and very often directly related to parameters related to failure modes limit state equations. An important issue to improve the characterization of subsoils and existing levees is to be able to combine acquired geophysical and geotechnical data, while taking into account their respective uncertainties, inaccuracies and spatial distributions. The complementarity of these two sets of methods is often underused since the uncertainty and inaccuracy associated with each method are rarely considered. Furthermore, results are usually only graphically superimposed and considered with an expert opinion instead of being mathematically merged. These works propose a specific methodology in order to manage conflictual information and different levels of uncertainties and inaccuracies from different investigation methods, expanding geotechnical information between borehole positions. It presents a new way of mathematically combining data from these two types of information sources, taking into account the specificities of each kind of method. This new methodology considers the framework fixed by the theory of belief masses and improves the characterization of lithological sets within levees and their foundation. It provides information on the level of conflict between information sources while proposing a confidence index associated with the results.

new geotechnical software

Rijkswaterstaat has launched new geotechnical software for slope stability on November 28th

This was developed together with Deltares and our dike reinforcement program HWBP (The Slope Stability Project / POV Macrostabiliteit).

Raymond van der Meij from Deltares was the main driving force behind the development. Meindert Van was one of the initiators.

We have merged the knowledge from five different initiatives in the Netherlands on slope stability in the new software.


It will be available on the Deltares and on the Rijkswaterstaat website (Helpdeskwater.nl)

It will be in the English language. The software is available to everyone (free of charge). Support for users who assess or design flood defenses in the Netherlands is covered by Rijkswaterstaat. Support for user in other countries will go through Deltares (this is not free of charge).


The user manual is available on



Request: information on drought effects (e.g., cracks) in levees

Dear all,

During last month’s EURCOLD Symposium I presented a paper on drought effects on levees; see https://www.researchgate.net/publication/336641742_Mitigating_drought_risk_for_levees_Mitigating_drought_risk_for_levees . For the Sept2020 Floodrisk Symposium, I wish to extend this work and include some more experiences regarding drought effects on levees. However, it turned out to be quite hard to find publications and data (such as drought crack dimensions+position and other properties, drought crack development and recovery, best practices on remedial measures, etc.). Who can help me out, and send me some useful weblinks/publications and/or [summarized] data?

Thanks in advance!

Marcel Bottema

Assessing and managing the risks of transitions in flood defence infrastructure


Workshop on  “Assessing and managing the risks of transitions in flood defence infrastructure”

The Environment Agency has teamed up with international experts to help risk management authorities to consider the risks associated with transitions in flood defence structures. The international consortium, made up of HR Wallingford, Royal HaskoningDHV, Deltares, IRSTEA and USACE, integrates current international knowledge and practice on transitions combined with working UK knowledge and practice on risk based tools for asset inspection and management. The project aims to:
• consider the presence of transitions during flood defence condition assessment
• quantify the effects of transitions on flood defence performance and flood risk
• manage the risk of transitions with improved design and retrofit solutions.

On 9 October a stakeholder meeting was hold in London to provide the opportunity to influence the direction of the project and to benefit from stakeholder’s experience managing flood defences. The animated discussion focused on specific reliability methods for transitions and the approaches for inspecting them. The workshop also provided the opportunity to hear about the management strategies being employed in the US, France and the Netherland to mitigate the risks associated with transitions.

Thoughts on ICOLD Congress, Vienna


photo by Ilze Plomp – van der Sar

This was my first ICOLD meeting and was the first formal ICOLD Technical Committee on Levees (TC LE) after it had been setup at the meeting in Prague. Here are a few of my thoughts.

Not only was this the first formal meeting of the LE TC the Congress was also important because Q103 for the congress was on the subject of small dams and levees. Rémy Tourment from France was the general reporter for this question who is also the chairman of the ICOLD TC LE. An interesting range of Reports were presented in four sessions with worthwhile discussion at the end of each session.

ICOLD TC LE also held a workshop on Monday 2 July. Other than providing an opportunity for presentations from new member countries, a significant amount of time was spent in gathering ideas for the dams and levees intercomparison report, using a facilitated brainstorming process. By the end we had a wall of Post It notes with very useful material. One point for the future is to use stickier notes as several did not stay on the wall. This material will be used by a small team from the Committee to further develop the report.
