Geophysical imaging of the subsurface seismic structure of the Chestnut Hill Reservoir earth embankment dam (Massachusetts)

Near Surface Geophysics, Volume 23, Issue 2, Page 105-120, April 2025.
Abstract Degradation within a manmade earth embankment structure is often unobservable from the surface. In order to evaluate the structural integrity of earth embankment levees and dams and identify subsurface zones of weakness that may result in the future failures of such structures, various geophysical methods have been proposed as effective ...

A machine vision‐based intelligent segmentation method for dam underwater cracks using swarm optimization algorithm and deep learning

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 10, Page 1405-1417, 18 April 2025.
Abstract Ensuring the safety of water networks is a research hotspot in the current water conservancy industry, and dams are an important part. However, over time, the dam is prone to varying degrees of aging and disease, most of which are structural cracks.

Effect of uncertainties in breach location and breach mechanisms on risk‐related classification of off‐stream reservoirs

Journal of Flood Risk Management, Volume 18, Issue 1, March 2025.
Abstract Off‐stream reservoirs are artificial water storage structures that increase the flood risk of an area. In some places, related risk reduction plans are based on a risk classification of these structures, which follows local water resource management regulations. These classification methods typically follow deterministic qualitative guidelines

Experimental Study of Dike‐Break Induced Flow Generated by Instantaneous Opening of the Side Gate

Journal of Flood Risk Management, Volume 18, Issue 1, March 2025.
ABSTRACT A large‐scale experimental model of instantaneous dike‐break induced flow was conducted in this work. Water level variations in the river channel and floodplain, breach discharge, and the surface velocity field at the breach were measured during dike failure.
