中文摘要
这项研究的目的是进行一项实地测试,以更好地确定台湾中部山区河流基岩侵蚀的机制,并量化基岩侵蚀量随河流水力和泥沙输移变量的变化。为了实现这一目标,我们必须在研究区选定的野外地点测量推移质输移率。因此,第二个目标是应用索恩和他的同事在海洋条件下开发的被动声学技术,来测量这些陡峭的山溪中的泥沙输送。据我们所知,这是这一努力的首次尝试。结果将是基岩磨损率的数据集,它是当地沉积物通量和其他重要变量的函数,如内在基岩可蚀性、河道水力学和运输中材料的粒度。这个数据集将被用来测试理论推导,最终目标是基于过程的、现场校准的河流基岩切割规律。
英文摘要
9903196SlingerlandThe objective of this research is to conduct a field test to better define the mechanisms of bedrock erosion occurring in streams draining the Central Range of Taiwan, and to quantify the amount of bedrock erosion as a function of stream hydraulic and sediment transport variables. In order to accomplish this goal we must measure bedload transport rates at selected field sites in the study area. Therefore a secondary goal is to apply the passive acoustic technique of Thorne and colleagues, developed under marine conditions, to measure bedload transport in these steep mountain streams. To our knowledge it is afirst attempt at this effort. The result will be a dataset of bedrock wear rates as a function of local sediment fluxes and other important variables such as intrinsic bedrock erodibility, channel hydraulics, and grain size of the material in transport. This dataset will be used to test theoretical derivations, with the ultimate goal a process-based, field calibrated fluvial bedrock incision law.
