9526954 Willett The objective of this research is to construct an improved orogenesis model and conduct numerical experiments that will reveal the nature and strengths of feedback between tectonic deformation and surface processes in evolving mountain belts. The experiments will be guided by a dataset of geologic and topographic observations of active mountain belts, collected both from the literature and digital elevation models. To accomplish this objective, two extant surface-processes models (SPMs) will be synthesized, and a new model constructed that accounts for orographic climate, chemical weathering, and alpine glaciation. The macrogeomorphology and exhumation patterns of a few carefully selected mountain belts will be predicted using the coupled model and the results tested against observations. The ultimate outcome of this research should be an improved underqtanding of the nature and strengths of feedback between tectonic deformation and surface processes in evolving mountain belts.

9526954威利特 本研究的目的是建立一个改进的造山模型，并进行数值试验，将揭示的性质和强度之间的反馈构造变形和表面过程在不断变化的山区带。 这些实验将由从文献和数字高程模型中收集的活动山区地质和地形观测数据集指导。 为了实现这一目标，两个现存的表面过程模型（SPM）将被合成，并构建一个新的模型，占地形气候，化学风化和高山冰川。 将使用耦合模型预测几个精心选择的山区带的宏观地貌和剥露模式，并将结果与观测结果进行检验。 这一研究的最终结果应该是对演化中的山地带中构造变形与地表过程之间反馈的性质和强度有更好的理解。
