Sediment yield as a desertification risk indicator [PDF]
Science of The Total Environment, 2011 Soil erosion is often regarded as one of the main processes of desertification. This has led to the use of various desertification indicators that are related to soil erosion. Most of these indicators focus, however, on small spatial units, while little attention has been given to the amount of sediment exported at the catchment scale.

Fluvial Response to Climate Change in the Pacific Northwest: Skeena River Discharge and Sediment Yield [PDF]
, 2022 Changes in climate affect the hydrological regime of rivers worldwide and differ with geographic location and basin characteristics. Such changes within a basin are captured in the flux of water and sediment at river mouths, which can impact coastal ...

Fluvial Sediment Yields in Hyper-Arid Areas, Exemplified by Nahal Nehushtan, Israel
Land, 2022 Floods rarely occur in hyper-arid deserts and little is known about the magnitude and frequency of sediment delivery from their basins, despite their importance to changes to the landscape, infrastructures and engineering activities.

Sediment Yield Modeling and Mapping of the Spatial Distribution of Soil Erosion-Prone Areas
Applied and Environmental Soil Science, 2022 Sediment movement is the most critical problem in Ethiopia, notably in the Ketar River watershed, which is located in the Rift Valley Basin. The Ketar River flows through rugged terrain with steep slopes and high sediment movement.

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 ...
