Bed load measurements during low flow in a desert gravel-bed stream, LasVegasWash, were used to evaluate fractional bed load transport equations. Since the stream is an urban perennial channel that conveys primarily treated waste effluent, bed load transport is limited by the supply of ...
通过把bedtool保存为bed文件,然后再load,这样就可以用 head()。 intersect 取交集, 不同参数结果输出不同的区域,A和B是输入的两个BED文件。不输入参数输出结果为两个BED文件的交集,-wa保留和b文件有重叠的全部A文件区域,-v 输出结果为-wa的补集,即B中没有A重叠的区域。可以用图表示为: a=pybedtools.exampl...
Streamflow and bedload transport in an obstruction-affected, gravel-bed stream The mechanisms of pool maintenance were investigated in a small (width = 10 m,drainage area = 18 km2), gravel-bed stream where pools are commonly associate... RD Smith - 《Streamflow》 被引量: 10发表: 1990年 B...
Bed load sediment transport, in which wind or water flowing over a bed of sediment causes grains to roll or hop along the bed, is a critically important mechanism in contexts ranging from river restoration1 to planetary exploration2. Despite its widespre

This paper reports a radiofrequency identification (RFID) tracing experiment implemented in a high-sediment-load mountain stream typical of alpine gravel-bed torrents. The study site is the Bouinenc Torrent, a tributary to the Bléone River in southeast France that drains a 38·9-km degraded cat...
Effect of sampling time on measured gravel bed load transport rates in a coarse-bedded stream. Water Resources Research, 41: 1–12. Article Google Scholar Cantalice J R B, Cunha Filho M, Stosic B D et al., 2013. Relation entre charge de fond et sédiments en suspension dans la ...
Bedload transport rates derived in this study vary both spatially and temporally by up to an order of magnitude. Upstream bedload supply parameters are believed to be more influential than specific stream power in controlling the transport patterns and changes in channel bed elevation observed. 展开...
