Why Do Rivers Curve?

YEC Geo's curator insight, December 7, 2014 8:15 PM

Actually a very good video.  My one quibble is with the introduction, when the narrator talks about mountain streams "carving" their gorges.  The puzzle of how small streams could possibly carve out deep bedrock canyons is an ongoing research problem, and is difficult to resolve from a gradualistic perspective.

Jason Schneider's curator insight, January 27, 2015 12:15 AM

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.

Mijnbouw en aardverschuivingen, een goede combinatie ...... 

PIRatE Lab's curator insight, April 7, 2014 11:48 AM

There are several reasons for mudslides--some are purely a result of physical geography and others are related to land use patterns.  This last week's mudslide in Washington state was a combination of the two and although this impacts one place (see on map), it is a good teaching moment to discuss the environmental impacts of land use patterns and resource extraction projects.  As seen in this interactive, the river was cutting at the base of the hill, while loggers were clear-cutting at the top of the mountain.  Trees help prevent erosion as the roots hold the soil in place--a critical piece to the puzzle in a very rainy climate.  With $1 million worth of timber on the slope, logging companies persisted despite objections from the Department of Natural Resources and some restrictions (but in hindsight, those restrictions clearly were not enough).

Questions to Consider: Other than economic worth, what other ways are there to value and evaluate the environment?  How could this landscape have been protected and managed better or was this mudslide inevitable?

Jake Red Dorman's curator insight, November 25, 2014 1:24 PM

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.

Kristin Mandsager San Bento's curator insight, January 27, 2015 4:50 PM

This seems like a useful tool to a degree.  But if we could actually simulate every destructive event then we would be miracle workers.  This was a sad event.  We have left such an imprint on the earth that it's starting to fight back.  We need to be more aware and careful with the one planet we have.  Climate changes are in the news more and more.  We can't ignore climate changes anymore.

Earthquakes in the Classroom

"An 8.2-magnitude earthquake struck off the coast of northern Chile, generating a local tsunami.  The USGS reported the earthquake was centered 95 km (59 miles) northwest of Iquique at a depth of 20.1km (12.5 miles).  This video gives the context for this type of earthquake."
