Landscape Evolution of the Central Kentucky Karst
Dr. Rachel Bosch
PhD Dissertation Research
Motivating questions
How do various erosional processes contribute to the evolution of karst landscapes? How does the subsurface respond to surface processes and how does the surface respond to subsurface processes? How do we investigate this interconnectedness and communicate it with other people?

Project 1
DKARST: modeling abrasional wear of scalloped bedrock in caves. What can we deduce about the sediment transport history of a cave passage by observing scallops?
Project 2
Measuring erosion of a scalloped limestone cave passage: Roaring River, Mammoth Cave. What is the erosion rate of a scalloped cave passage floor?
Project 3
A debris flow deposit in Mammoth Cave: field characterization. What series of geologic events led to the deposition of a large pile of siliciclastic sediments inside of Mammoth Cave?
Project 4
Stream capture from below: formation of the Sinkhole Plain, Kentucky, through the lens of relict topography. What sequence of events describe the exhumation of the Sinkhole Plain and what was their timing?
Project 5
Development and implementation of virtual field teaching resources: two karst geomorphology modules and three virtual capstone pathways. How do we communicate the field-rich concepts of karst hydrology and geomorphology to students who cannot get to the field?
