Description :
The energy based least action principle (LAP) has proven to be very successful for explaining natural phenomena. This paper briefly reviews its historical development and details how, in 3 ways, it governs the behaviour and stability of alluvial rivers. The paper focuses on the interpretation of how rivers adjust toward conditions that minimize change and maximize operational efficiency. Importantly, this study describes how iterative changes enable systems to achieve such a stable equilibrium.
