A simplified physically-based breach model for a high concrete-faced rockfill dam: A case study
Water Science and Engineering, 2018 A simplified physically-based model was developed to simulate the breaching process of the Gouhou concrete-faced rockfill dam (CFRD), which is the only breach case of a high CFRD in the world.

Numerical modeling of earthen dam breach due to piping failure
Water Science and Engineering, 2019 Based on model tests of earthen dam breach due to piping failure, a numerical model was developed. A key difference from previous research is the assumption that the cross-section of the pipe channel is an arch, with a rectangle at the bottom and a ...

Critical hydraulic gradient of soil flow failure in cohesive soil foundation
Yantu gongcheng xuebao, 2021 In view of the fact that the current formula for the critical hydraulic gradient is not suitable to solve the critical hydraulic gradient of cohesive soil, assuming that the seepage failure mode of the cohesive soil foundation is cylindrical or inverted ...

Managing accidents and failures of hydraulic structures [PDF]
MATEC Web of Conferences, 2019 While the prior objective of hydraulic structures is to remain in service, engineers must also be capable to adequately handle their failures. This paper gives guidance on this issue based on the European (mainly Dutch) and American practice. The discussion begins with terminology agreements on “accident” and “calamity”, followed by the notes on risk ...

Reliability assessment of water distribution systems with statistical entropy and other surrogate measures [PDF]
, 2010 There is ever increasing commercial and regulatory pressure to minimise the cost of water distribution networks even as the demand for them keeps on growing. But cost minimizing is only one of the demands placed on network design.
