💧We track water. Talking about hydrology & hydrogeology - dye tracing🔦🧪 - groundwater & surface water - karst & caves.

We're Amaël Poulain (Hydrogeo, Ph.D), Sofie de Volder (Biz Dev), and Maurel Leunte (Hydrogeo)

Krubera/Voronja Cave, in the Arabika Massif in Georgia, is the deepest known cave in the world.

The karst complex exceeds 2.000 metres in depth, with the deepest explored point reaching 2.199 metres (7.215 feet).

Karst landscapes, formed by dissolution of soluble rocks such as limestone, are gorgeous, but can pose a risk to infrastructure. Sinkholes, caves and underground drainage systems can remain hidden until the ground above them collapses.

Een "normale gemiddelde neerslaghoeveelheid" is niet geruststellend als slechts één heel erg regenachtige dag verantwoordelijk is voor dit gemiddelde.
