Verzakking

Verzakking is a type of subsidence that occurs when the ground surface collapses into a subsurface cavity or fissure. It is a common phenomenon in areas where there are soluble rocks, such as limestone or dolomite, which are capable of being dissolved by acidic water. The groundwater dissolves the rock, creating underground cavities, and as the rock collapses, the ground surface above it subsides.

Verzakking is often accompanied by other signs of karst terrain, such as sinkholes, dolines, and rock fractures.

The effects of verzakking can be varied and can range from minor subsidence to significant collapse of

Researchers have identified various mechanisms that contribute to the development of verzakking, including the presence of
