Linking Erosional and Climatic Processes in Regions of Active Mountain Building

Project description

The goal behind this project is to model climate-topography feedbacks and interactions. It is an advancement on current modeling efforts that may not capture the full variability associated with the interaction between climate and topography. For example, some precipitation models consider orographic effects, but these models may be oversimplifying the precipitation delivered to the evolving landscape, especially when threshold processes in both the climate and geomorphic systems are important. The research group plans to couple three models, CHILD, TopoFlow and WRF, in order to demonstrate and study the effects and feedbacks between climate and topography in regions of active mountain building. The coupled models will provide a high resolution scope on how climate plays a fundamental role in landscape evolution and how changes in elevations of an orogeny, through erosion and tectonics, provides feedback to the regional climate. The ultimate goal is a model of climate-topography interactions. We plan to test the role of different climate histories and regimes on landscape morphology by comparing topographies that evolve at different latitudes and under different orbital characteristics.

Objectives

• Successfully model and represent interactions between topography and climate. • Define feedbacks associated with the above interactions. • Differentiate interactions between climate and topography with respect to differing climate regimes. • Differentiate interactions between climate and topography through time.
