Experimental, Field and Modeling Approaches for Understanding Complex Karst Processes in the Critical Zone
Session ID#: 78588
Session Description:
Stress on water resources, water quality and related geohazards in karst region has increased significantly in recent decades, as karst aquifer partially supply drinking water resources to 1/4 of the world's population. The functioning of the critical zone extending from the groundwater system to the top of vegetation canopy plays an important role in water availability under a changing climate and human activities. Challenges are existed because of the special characteristics of the critical zone in karst, including the dynamic and heterogeneity of aquifer properties, thin soil profiles, and unique geochemistry processes. All these features result in complex hydrological, geochemical, and biological processes that affect water and solute transport over a wide range of spatial and temporal scales. Interdisciplinary studies, including field instrument development, mathematic modeling and interaction with other subjects are important in understanding water resources availability and biogeochemical dynamics in karst aquifers, and welcomed in this session.
