Photograph: The Design of Waters and the Geomorphic Sculpting of Floodplains

Cover caption: The photograph captures a remarkable example of an active crevasse splay in the lower reaches of the Negro River, within the Pantanal of Mato Grosso do Sul, Brazil. The image documents this geomorphological feature during the falling-water stage, highlighting the overflow of the main channel as it breaches the natural levee and deposits sandy sediments across the floodplain, which is colonized by dense native vegetation.
