Doctoral Dissertation: Spatio-temporal Variation in the Power of Mountain Streams

本论文的研究将考察科罗拉多州西南部和新墨西哥州北部山区分水岭水流功率的时空变化。水流功率是水流向下流动时能量消耗的时间比率，它是河流做功(即侵蚀堤岸或输送泥沙)能力的指标。主要根据实地收集的数据建立经验模型，以求确定水流功率与若干水文和地貌变量之间的关系。然后将预测(模型)流量与现场测量的流量进行比较。这项研究的总体重要性是对山溪水力学和地貌有更准确和准确的了解。

This dissertation research will examine spatial and temporal variation in stream power in a mountainous watershed in southwestern Colorado and northern New Mexico. Stream power is the time-rate of energy expenditure as water flows downslope, and it is an indicator of the ability of the stream to do work (i.e., erode its banks or transport sediment). The PIs seek to determine the relationships between stream power and a number of hydrologic and geomorphic variables by developing empirical models based primarily on data collected in the field. Predicted (model) flows will then be compared to flows measured in the field. The overall importance of this research is in generating a more accurate and precise understanding of mountain stream hydraulics and geomorphology.
