Lineage | The method involved delineating hydrogeomorphic units as discrete three dimensional units in which solution of the bedrock has resulted in the integration of surface water and ground water at various time scales. These karst hydrogeomorphic units were delineated based on bedrock type; depth to bedrock; topography; surface and subsurface hydrology; spring chemistry; and the distribution, landscape position, and type of surface and subsurface karst features. These elements combine to form a series of distinguishable units that constitute the karst system of Mower County. Water and material enter these units, move through the carbonate bedrock, and discharge either into streams or into lower bedrock aquifers. As a result, this map not only shows the known karst features but also relates that information to landscape morphology, depth to bedrock, bedrock geology, and ground-water age. |
