摘要

这项研究的目的是分析低水头水坝溃坝造成的水头切面扩展和下游沉积物产量。虽然其他地方已经提出了跟踪水坝溃坝/拆除造成的水头切削传播的框架，但很少有研究对由此造成的水头切削的下游泥沙产量进行计算。当坝顶切槽下游有水库时，沉积物产量尤其重要。本文估算了大蓝河低水头水坝溃坝导致塔特尔溪湖泥沙产量增加的情况。从 2018 年到 2022 年，坝顶切口估计为塔特尔溪湖带来了 859,000 立方米的沉积物。由于巨石溪流和基岩提供的天然坡度控制，侵蚀不太可能继续。

Sediment contributions from a low‐head dam failure on the Big Blue River near Marysville, KS

The purpose of this research is to analyze the headcut propagation and downstream sediment yield as a result of a low‐head dam failure. While frameworks have been presented elsewhere to track headcut propagation from a dam failure/removal, little research has been conducted to calculate the downstream sediment yield of the resulting headcut. The sediment yield is of particular interest when a reservoir is located downstream of the headcut. This paper estimates the increased sediment yield to Tuttle Creek Lake as a result of a low‐head dam failure on the Big Blue River. From 2018 to 2022, the headcut contributed an estimated 859,000 m3 of sediment to Tuttle Creek Lake. Erosion is unlikely to continue due to the presence of natural grade control provided by boulder riffles and bedrock.

期刊介绍： River Research and Applications , previously published as Regulated Rivers: Research and Management (1987-2001), is an international journal dedicated to the promotion of basic and applied scientific research on rivers. The journal publishes original scientific and technical papers on biological, ecological, geomorphological, hydrological, engineering and geographical aspects related to rivers in both the developed and developing world. Papers showing how basic studies and new science can be of use in applied problems associated with river management, regulation and restoration are encouraged as is interdisciplinary research concerned directly or indirectly with river management problems.
