Thanks to the Landsat program and Google Earth Engine, it is possible now to explore how the surface of the Earth has been changing through the last thirty years or so. Besides the obvious issues of interest, like changes in vegetation, the spread of cities, and the melting of glaciers, it is also possible to look at how rivers change their courses through time. This river is changing its course with an impressive speed; many – probably most – other rivers don’t show much obvious change during the same 30-year period. What determines the meander migration rate of rivers is an interesting question in fluvial geomorphology. The data that underlies Google Earth Engine is not accessible to everybody, but the Landsat data is available to anyone who creates a free account with Earth Explorer....
Satellite filmed, as the river changed its direction for decades. Unusual sight Ucayali River in Peru in a quarter century has undergone significant changes. It is now possible to learn due to the consistent imposition of pictures that the satellite took off in 1985. In total shooting took more than 30 years (from 1985 to 2016) Animated stream satellite imagery reminiscent of a cartoon. But really, that's what "living" river Ucayali River in Peru, right tributary of the Amazon. Despite poor image quality, seen as the main channel of the river gradually closes in one of the bends. A severed appendage is a small pond, which is almost looped (left). In addition, you can see how dry some parts of the shores over time, narrowing the mainstream.
near Puerto Sharara, wet season
Ucayali River in the middle of the jungle of Peru so peaceful ,green and just the noise of the animals =) ...well and the boat =/(just a detail) Rio Ucayali (selva alta)-Peru tan pacifico y verde solo el ruido de los animales y bueno del bote en este caso pero es solo un detallito no?
This is the port of Pucallpa where Heather, Kyama, Dick, Ruth, and Jeff left with a number of mission pastors on the 12 hour boat ride up the Ucayali river to the Peruvian jungle village of Samaria. This was part of a mission trip (from Brooklife Church in Wisconsin) to provide clean water and spread the word of Jesus to the people of Samaria, Grau, and to plant a church in Nueva Italia, Peru.

Approximate coordinates: 9° 25.223' S - 74° 18.205' W. This is a meander bend of incredible dynamism, affected by a heavy number of processes acting almost simultaneously such as chute cutoff, meander widening and narrowing or anastomising.

www.kipu.com www.franciscomariategui.com The Ucayali and Maranon rivers unite to form the famous Amazon river. This union takes place at 50 miles SW of Iquitos near the city of Nauta. It is very impressive to wath the birth of the biggest river on the planet. Los ríos Ucayali y Marañón se unen para dar nacimiento al famoso río Amazonas. Esta unión ocurre a 80 Kms al SW de Iquitos cerca del pueblo de Nauta. Es muy impresionante observar el nacimiento del río mas caudaloso del mundo. El río Ucayali tiene más de 1.900 kms. de longitud, ochenta por ciento de los cuales son navegables por navíos de hasta tres mil toneladas. El río Marañón nace en el Perú a 5.800 metros sobre el nivel del mar en el glaciar del nevado de Yapará. Tiene 1,600 kms. de largo.
