Geomorphological Processes, Scale and the Evolution of Fluvial Landforms

9318977 Tarboton降雨、径流、侵蚀、物质运动和沉积物运输是雕刻和形成景观的物理过程。地貌地貌是水文过程对景观作用的标志。河流景观具有由霍顿定律和许多其他标度定律量化的结构规律性。即使在不同的地质和气候环境中，这些经验关系的普遍性和解释力表明，河流地貌的普遍性和规律性超越了所涉及的特定过程的细节。目标是定量理解从单个山坡到完整的河流流域尺度上的景观过程和形式之间的关系，并研究缩放特性与地貌过程一般形式之间的关系。这种关系将通过数值模拟和对已量化地貌过程的实地数据的仔细分析来研究。

9318977 Tarboton Rainfall, runoff, erosion, mass movement, and sediment transport are the physical processes that sculpture and form the landscape. Geomorphological landforms are the signature of the action of hydrologic processes on the landscape. Fluvial landscapes have a structural regularity that has been quantified by Horton's and numerous other scaling laws. The ubiquity and explanatory strength of these empirical relationships, even in diverse geologic and climatic settings, suggests a deep universality and regularity in fluvial landorms that goes beyond the details of the particular processes involved. The objective is a quantitative understanding of the relationship between processes and form in landscapes at scales ranging from single hillslopes to complete river basins and investigate the relationship between scaling properties and the general form of geomorphic processes. This relationship will be investigated using numerical modeling together with careful analysis of field data where geomorphological processes have been quantified.
