Doline

A doline, also known as a sinkhole or swallow hole, is a closed depression found in karst landscapes. These depressions form due to the dissolution of soluble bedrock, typically limestone, dolomite, or gypsum, by acidic water. doline shapes vary widely, ranging from shallow bowls to steep-sided funnels. They play a significant role in groundwater recharge and can be hazardous if undetected due to the potential for collapse, leading to infrastructure damage or personal injury.

Doline meaning with examples

• During the storm, the area experienced severe flooding, with the dolines becoming rapidly filled with water. The local emergency services were on high alert as some roads showed signs of weakness around known sinkholes. Local authorities cautioned residents to remain vigilant and report any new sinkholes developing across their properties.
• The geologists are carefully studying the formation and evolution of the dolines in the karst region. They are collecting data to measure how the acidic rainfall affects the bedrock beneath the surface. They are also comparing the shapes of different dolines across the area, trying to understand the subsurface water flow and the formation mechanisms.
• The village faced significant infrastructure problems when a large doline suddenly opened up under a major road. The town was advised to implement a survey of the bedrock to prevent similar occurrences. Local engineering companies were brought in to investigate, and they recommended repairing the road and ensuring the area was properly inspected.
• The exploration team descended into the doline, equipped with specialized gear, hoping to discover a previously unknown cave system. They documented the features of the doline's interior including the geological strata exposed by the erosion and took measurements of the subterranean conditions. The experience showed the complex interaction of water and limestone.
