Integrated Turbulence and Machine Learning Models Explain Pier Scour in Erodible Channels
Water Resources Research, Volume 61, Issue 9, September 2025.Abstract Pier scour, a primary cause of bridge failures, stems from turbulent erosion at the pier's approach surface, jeopardizing bridge stability and influencing both river morphology and interactions between aquatic and terrestrial ecosystems. The scouring process, initiated by turbulent eddies interacting with sediments over erodible channels ...

A Turbulence Model for Velocity Distribution in Open‐Channel Flows Through Mangrove Trees
Water Resources Research, Volume 61, Issue 8, August 2025.Abstract The vertical distribution of flow velocity plays a critical role in sediment transport and nutrient circulation within mangrove forests, characterized by their intricate root structures. Existing velocity profile models typically rely on a single mixing length scale, limiting their ability to capture the energy distribution of turbulent eddies
