“…This system, however, is subject to flash flood events. The maximum instantaneous discharge was measured at 1,500 ft 3 /s in February 1969 (Anderson, 2005). A similar event occurred in December 2010 when stream discharge peaked at 1,050 ft 3 /s on the Amargosa River downstream of the OSTH at U.S. Geological Survey streamgage 10251300 (U.S. Geological Survey, 2016).…”

“…Without any age control, it is permissible that the sediment at Site 1 (Fig. 2), and all of the outcrops visited in this study, are relatively young (Holocene) and are not "Pleistocene basin fill" related to Lake Dumont (e.g., the majority of the deposits identified as Ql in Anderson andWells (2003, 1997) are not Pleistocene in age). However, the 18 ka age within a meter of the surface at the DU-2 core site suggests that at least those sediments are late Pleistocene in age, yet they do not contain Mojave River-tolerant ostracodes.…”

“…Onshore rivers may connect canyons directly into the river mouth (Babonneau et al 2002;Yu et al 2009;Hsiung and Yu 2012) or erode their way into a continental shelf during a lowstand period (Damuth 1994;Popescu et al 2004;Anderson 2005;Ding et al 2010). Hyperpycnal currents generated in rivers drive sediment transport on the sea bottom, thereby favoring the formation of canyons or channels.…”

The Pearl River Canyon system is a typical canyon system on the northern continental slope of the South China Sea, which has significant implications for hydrocarbon exploration. Through swath bathymetry in the canyon area combined with different types of seismic data, we have studied the morphotectonics and controlling factors of the canyon by analyzing its morphology and sedimentary structure, as well as the main features of the continental slope around the canyon. Results show that the Pearl River Canyon can be separated into three segments with different orientations. The upper reach is NW-oriented with a shallowly incised course, whereas the middle and lower reaches, that are located mainly in the Baiyun Sag, have a broad U-shape and have experienced consistent deposition. Seventeen deeply-cut canyons have developed in the slope north of the Baiyun Sag, playing an important role in the sedimentary processes of the middle and lower reaches of the Pearl River Canyon. These canyons display both asymmetrical V-and U-shapes along their lengths. Numerous buried channels can be identified below the modern canyons with unidirectionally migrating stacking patterns, suggesting that the canyons have experienced a cyclic evolution with several cut and fill phases of varying magnitude. These long established canyons, rather than the upper reach of the Pearl River Canyon, are the main conduits for the transport of terrigenous materials to the lower slope and abyssal basin during lowstand stage, and have contributed to the formation of vertically stacked deep-water fans in the middle reach. Canyon morphology is interpreted as a result of erosive sediment flows. The Pearl River Canyon and the 17 canyons in the slope area north of the Baiyun Sag probably have developed since the Miocene. Cenozoic tectonics, sea level change and sediment supply jointly control the morphology and sedimentary structure. The middle and lower reaches of the Pearl River Canyon developed on the paleo-terrain of the Baiyun Sag, which has been a persistently rapid depositional environment, receiving most of the materials transported via the canyons.
