Mapping River Bed Topography in Whitewater Rapids Using Bathymetric LiDAR

River Research and Applications, EarlyView.
ABSTRACT Bathymetric LiDAR captures river topography efficiently for clear and shallow water, but for mountain rivers, whitewater rapids still pose challenges. This study proposes a novel method to enable the extraction of bottom returns specifically in turbulent whitewater sections.

Large‐Scale Evaluation of Beach Morphodynamic Evolution and Environmental Drivers Along China's Eastern Coast Through Long‐Term Landsat Analysis

Earth's Future
Beach evolution severely impacts the economy and social well‐being of coastal communities, posing a threat to the safety of coastal infrastructure. Under the influence of rising sea levels and other various environmental variables, the coastal morphology

Using Fine Sediment Monitoring to Quantify Sand Loading Over Time

River Research and Applications, EarlyView.
ABSTRACT Riverine sand loading can lead to geomorphic change, impacting river processes like lateral migration and vertical aggradation or degradation. Yet many sediment monitoring programs track only fine sediment measurable as total suspended solids (TSS). Here, we assess the ability for TSS data to be used to determine sand loading.

Long‐Term Morphodynamic Responses to Flood Diversion in the Lower Kano River, Japan

River Research and Applications, EarlyView.
ABSTRACT Fluvial morphodynamics—the interaction between water flow, sediment transport, and channel morphology—is a central concern in sustainable river management. However, the long‐term effects of flood diversion remain underexplored. This study investigated the decadal‐scale morphodynamic responses of the lower Kano River in Japan following the ...

Geospatial technology based evaluation of recent morphodynamic changes and flow patterns in the upper Jhelum River

River, EarlyView.
Abstract This study was conducted to address the concerns over the changes in river morphology and their implications for sustainable river management. It investigates the morphological dynamics of the Upper Jhelum River between 2018 and 2023, using high‐resolution Sentinel‐2 imagery and advanced geospatial techniques to capture subtle yet significant ...

One-dimensional morphodynamic model coupling open-channel flow and turbidity current in reservoir

Journal of Hydrology and Hydromechanics, 2017
Traditional depth-averaged morphodynamic models for turbidity currents usually focus on the propagation of currents after plunging. However, owing to the unsteady characteristic of the plunge point locations and the tough conditions of field measurement ...

Response of river-dominated delta channel networks to permanent changes in river discharge [PDF]

, 2010
Using numerical experiments, we investigate how river-dominated delta channel networks are likely to respond to changes in river discharge predicted to occur over the next century as a result of environmental change.
