Most sediment transport equations overestimate the bedload transport rate by several times when applied to mountain rivers. This is due to the fact that the presence of large relatively immobile boulders, which disrupt the flow, is generally not taken into account. Sediment transport in steep channels with boulders was herein investigated using 41 laboratory experiments carried out on a tilting...

Bedload sediment transport in rivers can cause impacts, such as bed erosion/deposition, sandbank formation and changes flow capacity. sampling techniques have limitations related to spatial temporal resolution. These constraints are more relevant with dunes high transport. This paper presents a comparison between bedload rates estimated direct indirect methods river sand dunes. The case study a...

Understanding the properties of wildfire-disrupted catchments is crucial for managing river floods and landslide risks. Using a hydrophone, we investigated changes in sediment supply conditions small mountainous (30.8 ha) southern Korea 6 years (March 2014–December 2019). Bedload transport rates mostly increased burned 1–2 post-wildfire (early post-fire regime) but decreased 3 owing to coverage...
