When two currents collide, they wrap around each other and a whirlpool is formed. The most common place for this to happen is near a structure like a rock, bridge leg or island – the theory goes that a fast current will hit the obstruction and flow around it, leaving an area of low pressure immediately downstream. Nature’s response is an eddy circulating water against the prevailing current to ‘fill the gap’ of low pressure. The edge of the eddy, where the two currents collide, is called the ‘eddyline’ and is where whirlpools are generally found. On a small scale, I recently watched this
