Holocene landslides in the Fraser Canyon Corridor and implications for ‘ecohazard’ assessment

Earth Surface Processes and Landforms, Volume 50, Issue 6, May 2025.
Recent landslides affecting salmon migration in the Fraser River corridor are similar to many others that occurred during the Holocene. We propose an ‘ecohazard’ framework for determining the risk to salmon migration associated with different landslide styles throughout the Fraser River catchment.

Demystifying the discharge coefficient for flow over thin weirs and sills

Flow
A revised derivation of the discharge coefficient for flows over thin weirs and sills in the limits of wall overflow to a free overfall is given. Using dimensional analysis, we show that the discharge coefficient, $C_{d}$ , in the classical weir ...

Anchor chains—A simple low‐cost device to assist passage of small‐bodied mass fish

River Research and Applications, Volume 40, Issue 10, Page 1954-1970, December 2024.
Abstract Attention has been placed on a variety of barriers that hinder fish passage in modern times. The most prevalent fish barriers were culverts which have negatively impacted waterway connectivity and fish habitats. For small‐bodied mass fish, high barrel velocities and turbulence have reduced fish swimming performance because of their weak ...

Estimating critical depth and discharge over sloping rough end depth using machine learning

Journal of Hydroinformatics
This study uses machine learning (ML) to predict the end-depth structure's discharge and critical depth (yc). Linear regression, M5P, random forest, random tree, reduced error pruning tree, and Gaussian process (GP) are the ML methods used in this ...

Investigation of the free overfall for discharge measurement in stone bed triangular channels

Ain Shams Engineering Journal
This study utilizes the freefall as a simple and useful tool for measuring end depth discharge EDD in triangular channels having stone beds. For this task, forty-five triangular channel models are constructed and examined all having 360 cm length and end
