39 Understanding Karst Hydrology and Karst Aquifers Using Innovative Tracers and Other Technologies

We welcome submissions applying innovative tracers and other technologies to investigate karst hydrology and karst aquifers, including but not limited to complex interactions between surface water and groundwater, recharge processes, flow pathways, sediment transport, sustainability, and susceptibility to contaminants.
