Prediction of sediment transport capacity based on slope gradients and flow discharge. [PDF]

PLoS ONE, 2021
Sediment transport capacity (Tc) is an essential parameter in the establishment of the slope soil erosion model. Slope type is an important crucial factor affecting sediment transport capacity of overland flow, and vegetation can effectively inhibit soil

Assessment of plot-scale sediment transport on young moraines in the Swiss Alps using a fluorescent sand tracer [PDF]

Hydrology and Earth System Sciences, 2023
Glacial retreat uncovers large bodies of unconsolidated sediment that are prone to erosion. However, our knowledge of overland flow (OF) generation and sediment transport on moraines that have recently become ice-free is still limited. To investigate how

Assessment methodology for the prediction of landslide dam hazard [PDF]

Natural Hazards and Earth System Sciences, 2014
This paper represents a contribution to the study of hazard caused by the interaction between landslides and river courses. The effects of such interferences are often catastrophic and could include the formation of upstream lakes, potential dam failure,

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 ...
