Mine‐water immersion tests reveal pronounced coal weakening (vs. minor concrete degradation), identifying coal pillars as the stability‐limiting component in composite dams. A coupled FEINN framework quantifies extreme‐pressure stability and ranks multi‐parameter designs via a normalized multi‐indicator scheme, enabling optimized dam configuration for ...

Short‐Term Effects on Rill Erosion and Flow Resistance in a Wood‐Biochar Amended Soil
This investigation evaluates the short‐term effects of wood‐biochar addition, with two different concentrations (BC = 3 and 5%) to soil on rill erosion and flow resistance. The results demonstrated that, in the short term, the addition of BC = 3% is effective in reducing soil erosion phenomena as compared to the control condition, while adding BC = 5 ...

ABSTRACT Glacial Lake Fraser, which formed in British Columbia against the retreating Cordilleran Ice Sheet, stored ~520 km3 of water before its near‐total drainage into the Salish Sea during an outburst flood event. Despite the impact of the outburst flood on sediment transport and landscape evolution in the Fraser River valley, its peak discharge and

Evaluating novel attachment methods for tracking devices on terrestrial mammals
We deployed GNSS tracking devices on 2 endangered large terrestrial mammals, scimitar‐horned oryx and Przewalski's horses, using novel attachment methods. Tags achieved fix success rates and spatial accuracy that compare well with standard collars used on large mammals.

ABSTRACT Numerical simulation of hydraulic fracturing remains challenging due to the strong coupling between geomechanics and fluid flow when modelling multiple physical mechanisms of rock deformation, fracture evolution and fluid leak‐off. This study develops a coupled hydraulic fracture propagation framework that combines the extended finite element ...
