Monitoring spring discharge during storms.

This study shows that contrasts in geochemical data and water level response from two locations in a karst water shed provides a better understanding of the variety of flow paths in both space and time.

This study provides detailed mineralogy of the most readily transported fraction of the clastic sediment load revealing material with composition dependent on source area, on mixing within the aquifer, and on transport mechanisms.

This study points out that the mixing (both matrix and conduit water) can occur along different pathways (open versus closed) at different times and locations within the same basin.

Three karst springs in the folded Appalachians of Pennsylvaniawere monitored for stage, specific conductivity, and sediment concentration.

This study documents variations in calcium and nitrate concentrations that suggest changes in recharge pathways in a karst spring.

Urban karst systems are typically considered more vulnerable to contaminationand excess storm discharge because of potential sources areas, increased sedimentloading, and focusing of water from impervious surfaces.

Karst aquifers respond as an intermediate between surface and ground water in terms of flow regimes
