Evolution of Active Landscapes
STGL members study how landforms reflect the rates and modes of erosive processes over time, ranging from tectonically active mountain belts to quiescent regions responding to base-level adjustment.
We are investigating the linkages between lithology, weathering and the form of soil mantled topographies. In particular we seek to understand 1) if lithologic variations are expressed in the form of hillslopes and 2) if weathering of poorly consolidated rocks can increase the erosional resistance of materials exposed at earth’s surface. This study utilizes field observations and measurements, numerical modelling, and high resolution topographic data with a focus on the Gabilan Mesa, a location that previous studies have utilized as an ideal soil mantled landscape.
