9803484 Ellis One of the critical questions in tectonics regards the relationship among tectonic uplift, erosion and landscape, and climate. The question relates to the relative rates of erosion and uplift, and how they are affected by climate. This study will model landscape evolution over an active blind thrust fault. Areas will be studied where the rates of bedrock landsliding, fluvial incision, regolith production, and hill slope diffusion can be calibrated. If successful, this study will determine how sensitive the topography is to fault geometry and slip rate, and to quantify the competition between tectonics and climate.

9803484 Ellis是构造学中的关键问题之一，涉及到构造抬升、侵蚀、景观和气候之间的关系。这个问题涉及侵蚀和隆升的相对速度，以及它们如何受到气候的影响。这项研究将模拟一条活动的盲冲断层上的地貌演化。将研究基岩滑坡、河流切割、风化岩层产生和山坡扩散的速率可以校准的地区。如果成功，这项研究将确定地形对断层几何形状和滑动速度的敏感度，并量化构造和气候之间的竞争。
