Short summary
Dams and reservoirs in karst areas often struggle with significant leakage, making construction both challenging and costly. This study uses a numerical model to show how karst aquifers in water divide regions evolve to form low-karstified rock-blocks (LKB). It also explores how and when these LKBs can significantly reduce leakage across the water divides if a reservoir is built on one side.
