Fine-tuning the evaluation of suffusion of silt-sand-gravel soils – a comparative study of LTU and UNSW tests: (Paper and Abstract)

Swedish embankment dams are usually constructed with core soils of glacial till. A widely graded soil sourced from moraine deposits, till comprises many fractions, from silt and sand to gravel and stones, all crushed and mixed by the action of glaciation. Interestingly, this type of soil is remarkably similar to that in other parts of the world...

Internal erosion in dams and dikes: a comparison: (Paper and Abstract)

Dams and dikes are both water-retaining earth embankments. These are vulnerable to internal erosion but specific differences lead to varying vulnerabilities to different types of internal erosion: • Dams are usually zoned, with potential filtering capability to arrest piping if it is initiated, while dikes are more commonly unzoned and incapable...

Laboratory Tests for Backwards Piping Erosion

The U.S. Army Engineer Research and Development Center (ERDC) is conducting research to investigate internal erosion, specifically backward erosion piping, by use of laboratory-scale model testing to understand and properly capture the physics of the problem. Preliminary results show that lower void ratio models, using poorly-graded soils with a...
