From 20 – 24 April 2020, the Tenth International Symposium on Land Subsidence (TISOLS) will take place in Delft - Gouda, the Netherlands.

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.
