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.

The geomorphic processes that produce landforms, including a case study of at least one landform

"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."

"The largest reservoir in the U.S. falls to its lowest water level in history, Nevada State Sen. Tick Segerblom introduced a bill title and issued a press release on July 8 calling for an 'independent scientific and economic audit of the Bureau of Reclamation’s strategies for Colorado River management.'" This week’s history-making, bad-news event at Lake Mead has already triggered lots of news stories, but almost all of these stories focus on the water supply for Las Vegas, Phoenix and California. But what about the health of the river itself? Tags: physical, fluvial, drought, water, environment.

Many geographers are aware that future water resource issues in the American Southwest will have political, cultural, and social impacts. What do you believe to be some approaching concerns after reading this article? |
For the beauty of this picture. Follow the link to see the ancient courses of Mississippi River, I had once the idea to draw maps of the lower course of the Loue River in France not in a scientific purpose, but just for a kind of fractal art.
