Adjustment patterns and causes of the morphology of sandy riverbed downstream of the Three Gorges Dam

Shui kexue jinzhan, 2020
The operation of the Three Gorges Reservoir has altered the water and sediment conditions downstream of the dam, resulting in adaptive adjustments in riverbed by scouring and silting, as well as shoal and beach morphology.

River flow analyses for flood projection in the Kabul River Basin

Central Asian Journal of Water Research, 2020
Flooding is one of the critical natural disasters in Afghanistan, causing huge social and economic losses on an annual basis. Due to lack of historical data and long gaps in the recorded data, flood predictions are usually associated with large ...

Water induced sediment levitation enhances downslope transport on Mars [PDF]

, 2017
On Mars, locally warm surface temperatures (~293 K) occur, leading to the possibility of (transient) liquid water on the surface. However, water exposed to the martian atmosphere will boil, and the sediment transport capacity of such unstable water is ...

Sampling Strategies to Improve Passive Optical Remote Sensing of River Bathymetry

Remote Sensing, 2018
Passive optical remote sensing of river bathymetry involves establishing a relation between depth and reflectance that can be applied throughout an image to produce a depth map. Building upon the Optimal Band Ratio Analysis (OBRA) framework, we introduce

Low water temperature sediment transport effects of the hyperconcentrated river: a case study of Bayangaole station in the upper Yellow River

Shui kexue jinzhan, 2020
The Yellow River is the river with the highest sediment concentration in the world. The sediment transport of the desert-wide valley reaches in the upper Yellow River are affected by inflow, sediment and changes in topographic conditions. To research the

Sediment transport by runoff on debris-mantled dryland hillslopes [PDF]

, 2012
Hillslopes supply sediment to river channels, and therefore impact drainage basin functioning and evolution. The relationship between hillslope attributes and sediment flux forms the basis of geomorphic transport laws used to model the long-term ...

Sediment transport and dispersal in the nearshore of “flash-flood” rivers [PDF]

, 2014
River sediment dispersal on the near-shore of “flash-flood” rivers is investigated using a coupled wave-current-sediment transport model. Besòs and Llobregat rivers (short and mountainous rivers in NW Mediterranean Sea, near to Barcelona City) are used ...

Paleogeographic numerical modeling of marginal seas for the Holocene – an exemplary study of the Baltic Sea [PDF]

Earth System Dynamics
The sustainable management of marginal seas is based on a thorough understanding of their evolutionary trends in the past. The paleogeographic evolution of marginal seas is controlled not only by global and regional driving forces (eustatic sea-level ...

Grain-size characteristics and net transport patterns of surficial sediments in the Zhejiang nearshore area, East China Sea

Oceanologia, 2020
Summary: Spatial variations in grain-size parameters can reflect sediment transport patterns and depositional dynamic environments. Therefore, 616 surficial sediment samples taken from the Zhejiang nearshore area in the East China Sea were analyzed to ...
