Abstract: 

This study looks at seasonality of solution processes in the karst terrain of the Marble Mountains. The Marble Mountains study area is dominated by subsurface flows which are characteristic of karst terrrain. Water samples collected from surface streams throughout the drainage area show influence of climate and soil cover on water chemistry over time.

Results from sample analysis show increasing levels of solutes with decreasing discharge. Discharge is at a peak in early spring and gradually diminishes into the fall. The decrease in discharge results in the reduction of the dilution effect causing solute levels to rise. The snowmelt pulse of solutes partially offsets early dilution. Soil CO2 levels peak in mid-summer and are followed by an increase in calcium hardness in areas draining mantled karst.
