Karst spring overexploitation possibility - case study of the Krupac spring

摘要

Insufficient water in the hydrologically critical part of the year is a problem often present in sub-arid areas. Human water demand and climate change compound the problem. This paper discusses the possibility of karst spring overexploitation, where there is a siphon-shaped cavity inside the mountain. Additionally, the paper presents some basic information related to the test area and Krupac Spring investigations including diving. The project, successfully implemented about 10 years ago, has provided the city of Nis with an additional 200 1/s of spring water during the mostcritical part of the year.
