9th International SedNet Conference,
23-26 September 2015, Krakow, Poland
“Solving societal challenges; working with sediments”

The conference is hosted and co-organized by the Faculty of Geology, Geophysics and Environmental Protection, AGH University of Science and Technology.

Sediments and society – what is the connection? Sediments – unseen or unnoticed most of the time – have a variety of impacts on human activities and vice versa, particularly along rivers. If the river is used for shipping, too much sediment may become an obstacle. The foundations of bridges may become unstable if too little sediment is available, creating a safety risk. After flooding, sediments are distributed over flood plains and with increased construction in natural flood plains these sediments add to the clean-up efforts and may become a health issue if contaminated. Even more dangerous are the mud and debris flows that can occur during larger floods.

Our aquatic resources are linked to sediment with its many and sometimes conflicting ecosystem services: recycling of nutrients, providing habitats for fish, adsorbing pollutants… But different ecosystem services are accompanied by different interests. How to deal along a watershed with too much or too little sediment? What to do about contaminated sediment that is mobile and may be taken downstream with the next flood? Or what about the contamination that stays in place but affects the local ecology and regional communities? Does contaminated mean “dangerous”? What is “too much” or “enough” sediment in a river and does it justify e.g. dredging or sand exploitation or are there alternatives?

Different countries have different experiences with the quantity and quality of sediments in their rivers, and with dealing with the challenges that arise from there. The role, attributed function and perception of sediments influence the way it is managed in a river system. At the core of the SedNet conference in 2015 will be the link between sediment and society, and the exchange of knowledge and respective experiences on an international level. Sediments are an integral part of the river system. Is this role acknowledged in a sufficient way?

Accompanying persons
Is your partner joining your trip to Krakow? SedNet is willing to bring ‘accompanying persons’ into contact with each other, so that they can make tours together.


Call for Sediment stories!

2015 is proclaimed as the International Year of Soils. OVAM – Public Waste Agency of Flanders – had the idea to capitalise the momentum and to raise awareness about the role of soils, sediments and land. But instead of using raw facts and numbers, OVAM chose to use a more visual and appropriate language and are using ‘soil stories’. “Facts tell, but stories sell”. And also want to tell WHY we do things rather then WHAT we do.

To reach the general public, politicians and policy makers, it is important to show how soils and sediments help to provide solutions for current societal challenges. On you can already find some inspirational stories about the positive aspects of soils.

OVAM wishes to expand the website with sediment stories. We therefore invite you to take a look at the stories, reflect on your own inspiring experiences and submit your own stories via Or share them on twitter using the hashtag #soilstories. It is not easy to make a connection between sediments and f.i. living environment, economy, health, innovation, but it will help us to ‘sell’ our work, to make our work more visible. It can help us to tell ‘why’ sediments are important.

At the SedNet conference in Krakow later this year, we will get back on this issue.


Awareness and Policy on Emerging Contaminants in Europe

Commissioned by the Dutch Ministry of Infrastructure and Environment (I&M) and the OVAM (Flanders), Witteveen+Bos and TTE consultants initiated an inventory on the awareness and policy on emerging contaminants in Europe. This inventory aims to wrap up available information, knowledge and experience related to legislation, governance and policy. Also SedNet members are kindly asked for their willingness to complete this questionnaire. The focus is on the presence in contaminated land and river basins (including sediment), and the aim is to focus on the curative policy for emerging contaminants in soil, groundwater and sediments.

For this project this questionnaire and a website is developed: Please look at this website for further information.

The results of this inventory are presented during the SedNet conference in Krakow (September 2015).

Thank you for your contribution!
