"The reason streams meander has been debated for some time, and a number of theories have come into play about why streams follow these meander patterns. One of the theories is that this is a way for rivers to dissipate their energy in a uniform way. A system that dissipates energy in sudden bursts tends to be unstable, whereas a system that tends to dissipate energy evenly tends to be relatively stable."
