What is the purpose of performing tests at different scales?
What is the purpose of performing tests at different scales?
- To investigate the effect of dike seepage length
- To determine the influence of particle size on erosion
- To validate the piping rule in formula (correct)
- To study the role of relative density and uniformity
How was the piping rule extended based on the small-scale tests?
How was the piping rule extended based on the small-scale tests?
- By accounting for the role of relative density, uniformity, and angularity (correct)
- By adjusting the influence of particle diameter
- By incorporating the effect of dike seepage length
- By considering the influence of particle shape and angularity
What is the preliminary hypothesis regarding the role of particle diameter?
What is the preliminary hypothesis regarding the role of particle diameter?
- Larger particles require a higher critical head to initiate erosion
- Smaller particles are better suited for a 2D erosion field approach (correct)
- Particle diameter has no significant impact on the erosion process
- Larger particles lead to more erosion due to increased discharge
