Slope with different reinforcement method and different failure
With Weak layer
Centrifuge modelling of clay slope with montmorillonite weak layer under rainfall conditions
With bed rock
Centrifuge Model Test Study on Failure Behavior of Soil Slopes Overlying the Bedrock
A single idea or small question can become a journal paper.
It is so strong scientific ability. By observing natural phenomena, then they model it, analyze it, experiment it and finally publish it in a top journal. It is so cool for using some simple equation to explain a natural phenomenon.

It is useful for investigating some fundamental questions, which not only shows your elaborate work and also lays a firm foundation for furture researches.
