PELA was one of the early karst authorities of the modern era, conducting formative studies on sinkhole occurrence and karstic ground-water flow. The fact that 20% of the earth’s surface is limestone or karst terrain, along with PELA’s extensive background in the study of karst terrains and water resources management, has gained the firm international recognition.
