The Yucatán Peninsula: Karst Hydrology and Sinkhole-Dominated Freshwater Access
尤卡坦半岛：喀斯特水文与天坑主导的淡水供给系统
-
The Yucatán Peninsula lacks surface rivers due to its porous limestone bedrock.
-
Rainwater rapidly infiltrates through fractures, forming extensive underground aquifers and caverns.
-
Cenotes—natural sinkholes—are windows into this subterranean water network.
-
These features result from limestone dissolution and roof collapse over millennia.
-
Cenotes vary in size, depth, and connectivity, creating localized freshwater oases in dry seasons.
-
Their spatial distribution reflects underlying joint patterns and regional groundwater flow directions.
-
Maya civilization strategically settled near cenotes for reliable water and ritual significance.
-
Modern tourism and agriculture now strain aquifer recharge rates across the peninsula.
-
Saltwater intrusion threatens coastal cenotes as sea levels rise and pumping increases.
-
This karst landscape demonstrates how geology dictates hydrological accessibility and human settlement patterns.
