Effects of particle size on crushing and deformation behaviors of rockfill materials
, 2020 Strength and deformation behaviors of rockfill materials, key factors for determining the stability of dams, pertain strongly to the grain crushing characteristics. In this study, single-particle crushing tests were carried out on rockfill materials with

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.

Modelling the equalizing process of rockfill dumps with a plough: Subsea cut and transport processes
, 2011 A way to equalize granular rockfill dumps at a sea or river bed is the use of a plough. A plough can be modeled as a set of straight blades in sequence. Several cutting models for dry and saturated sand are present in the literature.

Experimental study on effect of scaling on compact density of coarse-grained soils
Yantu gongcheng xuebao, 2019 There is a certain difference in compact density of rockfill materials between the real gradation and corresponding scaling gradation. In order to describe the difference quantitatively, the scaling effect can be divided into two parts, changes of the ...
