Rivers and river basins visualized by Hungarian geographer Robert Szucs. “Rivers are amazing. I worked a lot with spatial data during my studies in geography and GIS, and you just see what nature can draw is incredible. Still, all the river maps you see look the same, boring, unspectacular.

Ghost meanders and spectral silt traces: Harold Fisk's maps of the Mississippi's former curving courses (made 1941-44) are works of wonder. An oldie but a goodie -pop up drainage basins.

Earth - The highest waterfall on Earth. ***Satellite view of a river changing course. *** Island switches sovereignty every 6 months: Pheasant Island – France / Spain. On the western border between France and Spain, wedged between the two countries, there lies a two-acre island with no sign of human interference, save an inscribed white monument in the middle.
It may look like nothing special, but this little splotch of land is actually home to centuries of history, and one of the most unique border irregularities in the world. Pheasant Island, situated in the center of the Bidasoa River, is known as a “condominium,” a territory belonging to two separate nations at the same time. Every six months, representatives from France and Spain meet on Pheasant Island to exchange official papers, handing sovereignty of the island from one country to the other. Not only is Pheasant Island the world’s longest-lasting condominium, it is also the only one to alternate sovereignty between the two countries throughout the year, as opposed to condominiums like Antarctica, where countries share sovereignty over the land simultaneously.

The River Severn From Source to Mouth. Rivers through time, as seen in Landsat images « Hindered Settling. 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. You have probably already seen the images of the migrating Ucayali River in Peru, for example here. 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.
