Abstract:
... The morphological unit (MU) characterizes river landforms at the scale of ~0.5–5 channel widths. Geomorphic theory posits that ceteris paribus under a stationary flow and sediment regime, a river's channel pattern and its MU assemblage will also be stationary. This study tested that conjecture for the dynamic, gravel/cobble lower Yuba River. The MU assemblage consisting of eight in-channel bed typ ...

Abstract:
... Marine nepheloid layer is widely distributed in the oceans and marginal seas. The concentration of suspended particles in the nepheloid layer is significantly higher than that of the adjacent layers. Marine nepheloid layers include the surface nepheloid layer (SNL), intermediate nepheloid layer (INL), and bottom nepheloid layer (BNL). As a transport pathway for the particulate matter in the oceans ...

Downwearing rates of shore platform have been quantified with a number of ground-based techniques (such as the micro-erosion meter (MEM)), providing knowledge of the evolution of coastal landforms. However, it remains problematic to extrapolate the micro erosion results to the landform scale. This is because only a very small proportion of the platform is monitored and usually biased to flat rock ...

Abstract:
... Defining river networks from a digital elevation model (DEM) is a critical step in many hydrological studies. Most methods rely on analyses of flow accumulation based on a single drainage area threshold value. Landscape heterogeneity hinders the definition of drainage pixels by exceeding a threshold. In this study, we propose a method that automatically accounts for variable drainage density in th ...
