25925374Xingu RiverThe easternmost segment of the Great Bend of the Xingu River.
In this segment, the river as a whole generally runs in the north by northeast direction, but the water is split (especially at low tide) into a myriad narrow criscrossing channels that follow fault lines in the bedrock bottom, sometimes at 90 degrees or more from the general course. The channels are often interrupted by rapids. Part of the area is exposed bedrock, presumably flooded in the rainy season. Many islands of permanent vegetation are scattered among the channels. A few smoother channels are apparently formed along the margins by alluvial islands.
This is an experiment. This part of the river is being entered as a polygon because the two margins are too complex and independent for the Riversisdes mechanism. The approach will soon be discussed in the forum, please let it stand for a while.-51.7318889-3.353904BrazilAmapaOiapoque35935-3.1114414-3.5963666-51.596121-51.8676567
