Preliminary Investigations of Seasonal Changes in the Geochemical Evolution of the Logdson River, Mammoth Cave, Kentucky

摘要: Many geochemical studies have been made of karst waters worldwide. Most data that provide the framework for our current understanding evolution come from sampling at discrete times and locations, such as springs or wells. Relatively few groundwater it moves through an open flow system. This paper addresses seasonal changes in geochemistry Logsdon River conduit passes nearly 10km carbonate aquifer south-central Kentucky. The most important control on ability groundwaters to dissolve limestone is their carbon dioxide pressure, which influenced by a variety complex interactions with soil, bedrock, in-cave organic decay. fieldwork involved this research combines entire traversable length conduit, well continuous monitoring chemistry key points within Preliminary results study indicate both CO2, transport Mammoth Cave during summer winter conditions, along significant water distance 10km.
