Investigating the long-term landscape evolution for various combinations of climatic and geologic conditions

Landscape evolution is a continuous process driven by fluvial, tectonic, and biological processes among others. The response of landscape to different combinations of tectonic and climatic conditions has been a core subject of studying the Earth surface processes. While actual landscapes exhibit highly complex settings, it would be ideal if we can understand basic behavior of landscape under simplest conditions. To pursue this desire, we investigate how a theoretical landscape develops under ideal combinations using a numerical model named LEGS [Paik, 2012]. We investigate various combinations of tectonic uplift conditions, sinusoidal precipitation time series, and orographic effects and will present scientific insights obtained from the simple combinations.
