An Analysis Of Base-Level Conduit Sedimentation In South Central Kentucky, Ben Tobin
An Analysis Of Base-Level Conduit Sedimentation In South Central Kentucky, Ben Tobin
Masters Theses & Specialist Projects
In karst basins, significant amounts of surface-derived sediment can enter into cave systems. The transport and deposition of these sediments in underground streams is a function of flow velocity, sediment supply and passage morphology. Changes in the surface environment can affect the water and sediment supplies to subsurface drainage systems and thus may be reflected in the sedimentary structure, texture and rates of deposition of cave sediments. Cave sediments in two south central Kentucky caves were studied to evaluate a possible, relationship between variations in deposit characteristics and variations in surface changes, including land-use. Samples were collected using coring tubes …
Storm Response And Water Balance Of Temperate Rainforest Karst Watersheds: Tongass National Forest, Alaska, Johanna Kovarik
Storm Response And Water Balance Of Temperate Rainforest Karst Watersheds: Tongass National Forest, Alaska, Johanna Kovarik
Masters Theses & Specialist Projects
The Tongass National Forest in southeast Alaska contains 2,176 square kilometers of karst. As part of the evolving Tongass Land Management Plan, research into the function of karst systems is crucial in understanding how forest management affects not only karst areas but also surrounding ecosystems. Dye trace and water balance results in two watersheds on the north end of Prince of Wales Island demonstrate the difficulty in containing the effects of management, as water can enter karst catchments from unknown sources at different flow regimes. A dye trace was conducted in Windgate and Canyon Block watersheds. Two sinking streams were …
