TISOLS is scheduled for 17-21 april 2023

On behalf of the Organising Committee, we are pleased to announce that after a three-year delay the 10th International Symposium on Land Subsidence will take place in Delft–Gouda, the Netherlands from 17 – 21 April 2023.

The symposium is organised under the auspices of the Unesco IHP Land Subsidence International Initiative. This group has endeavoured to improve and disseminate knowledge on land subsidence since the 1970s, through International Symposia on Land Subsidence, collaborative projects and publications.

Land subsidence, or land-level lowering, is a major problem that threatens the viability and sustainable economic development for millions of people throughout the world, especially in (but not restricted to) highly urbanized coastal areas. It is often a result of overexploitation of groundwater resources. The total costs globally amount up to many billions of dollars annually.

Venue
TISOLS2023 will be held from 17 – 21 April 2023 at the Aula of the Delft University of Technology in Delft in combination with a Subsidence Day in the historical city of Gouda. The city of Delft is well known for its Delft Blue pottery and the cheese from Gouda is world famous. However, both cities are also located in the heart of the subsiding Dutch coastal plain. Subsidence has made the Netherlands to what it is today; a water-rich country which is one third below sea level. The Netherlands are still subsiding, causing damage to infrastructure and buildings. On top of that, land subsidence is worrisome for an already low-lying country that has to cope with sea-level rise.

Living with Subsidence 

Land subsidence, or land-level lowering, is a major problem that threatens the viability and sustainable economic development for millions of people throughout the world, especially in (but not restricted to) highly urbanized coastal areas. It is often a result of overexploitation of groundwater resources. The total costs globally amount up to many billions of dollars annually.

New innovative technologies and approaches are needed to reduce or, in the best case, to stop land subsidence. TISOLS intends to bring together international experts to share the latest research and insights on natural and anthropogenic land-level lowering.

At TISOLS in the Netherlands, we provide a platform to share our understanding of land subsidence, reliable data, and innovative techniques. Ultimately, we aim to increase the acknowledgement of the land subsidence problem in order to devise targeted strategies and solutions for long-term sustainable living conditions in subsiding areas. This means that at TISOLS we take on the challenge that lies in linking hydrological, geotechnical and geological knowledge to policy and socially acceptable solutions.

TISOLS is organized under the auspices of the Unesco IHP Land Subsidence International Initiative. This working group has endeavored to improve and disseminate knowledge on land subsidence since the 1970s, through International Symposia on Land Subsidence, collaborative projects and publications.
