"Confluences occur wherever two streams come together. If the gradient is low (i.e., nearly level) and the properties of the two streams are very different, the confluences may be characterized by a dramatic visible distinction as the mixing occurs only slowly." Tags: physical, fluvial, geomorphology, erosion, landscape.

El Sire Reserve in Peru is a river that has been monitored over the last 28 years. Every time I watch this short 6 second clip, I learn something different about how this river has changed. On the bottom of the screen, just past half way, the river just takes a huge short cut and cuts over and connects to a different part of the same river. This happens on the whole river too. there are 8 or 9 huge bends and curves in the river but by the end in 2012 there are only about 3 to 4 bends and curves. For some reason the water is taking short cuts and just leaving the spaces where the water used to run through and leaving it dry.

This is such a tangible way of showing things that seem abstract on a static map. |

For hundreds of years, on the eighth month of the lunar calendar, people have gathered along the shores of China’s Qiantang River at the head of Hangzhou Bay to witness the waves of its famous bore tide. Higher-than-normal high tides push into the harbor, funneling into the river, causing a broad wave that can reach up to 30 feet high. If the waves surge over the banks, spectators can be swept up, pushed along walkways or down embankments. Below, I’ve gathered images from the past few years of the Qiantang bore tides.

A very siual form using simple language to explain the meandering of rivers. Applicable to the course work on Hydrosphere.

So pretty much, the water controls rivers rather than particles controlling the river. Also, it appears that the motion and strength of the water causes rivers to bend and form in different curves. I'd like to think of it as a ball bouncing from side to side and every time it touches the border land of a river, it expands to the opposite side. However, when the water flow is hitting the side of a river, the opposite side is not getting any force from the water flow. In that case, the side that is not getting hit by the water flow slowly moves to the side that is being by the water flow causing river curves.

Sometimes the natural world finds ways to adapt to human environmental changes.
Useful when studying inland water / rivers for the option study.
