TISOLS: Tenth International Symposium on Land Subsidence

We are very sorry to inform you that the Tenth International Symposium on Land Subsidence ( TISOLS) in the Netherlands has been postponed to 17-21 May 2021 due to the general concerns surrounding the COVID-19 virus and the travel restriction for many participants. As your comfort and safety is our top priority, it has been decided that this is the best course of action to give as many people as possible the chance to attend the congress without exposing them to health risks..

  • We will cancel all registrations and reimburse any paid registration fee.
  • The Proceedings of the International Association of Hydrological Sciences special issue dedicated to TISOLS will be published as scheduled the coming weeks.
  • From September 2020 onwards, we will open registration and abstract submission for TISOLS in May 2021.
  • Authors with a paper in the TISOLS proceedings will be provided the opportunity to present their (updated) research in 2021.
  • New abstracts are additionally welcomed. No new proceeding papers will be required to participate.

Please check this website  for further updates on the new dates for TISOLS.

We will try to make the best out of this unfortunate situation and are giving our best to make the transition as easy as possible. We appreciate your cooperation and understanding immensely!

We hope to welcome you in the Netherlands from 17-21 May 2021.

Stay healthy and see you at TISOLS2021!

We are pleased to invite you to take part in the 10th International Symposium on Land Subsidence which will take place in Delft–Gouda, the Netherlands. The symposium is organised under the auspices of the Unesco IHP Land Subsidence International Initiative. This group has endeavored to improve and disseminate knowledge on land subsidence since the 1970s, through International Symposia on Land Subsidence, collaborative projects and publications.
TISOLS2021 will be held at the Aula of the Delft University of Technology in Delft in combination with a visit to the historical city of Gouda (Monday). Both cities are located in the heart of the subsiding Dutch coastal plain.

Following an icebreaker on Sunday 19 April, we will kick off TISOLS with The Subsidence & Science day on Monday 20 April in the St. Jans Church in Gouda where subsidence science meets decision makers and policy makers.
On Tuesday, Thursday and Friday we have an inspiring scientific programme.
On Wednesday 22 April excursions are planned to various locations in the Netherlands. And for those interested we have organised a 2-day visit to Ameland, one of the Wadden Sea Islands, from Friday 24 – Sunday 26 April.
