N2 - Puerto Maldonado city (~85,000 inhabitants), one of the largest urban areas within the Peruvian Amazon, is situated on a meander neck of the Madre de Dios River, a large meandering river. In 2016, a twelve-steel sheet-pile groyne system (lengths ranging 50-98 m) were built at La Pastora—a site located at the upstream bend inflection point—, to protect the levee and the city infrastructure. This contribution reports bedform observations associated to the groyne system in operation, which appears to be the first ever built in this environmental setting. An initial analysis conducted by means of a three-dimensional index suggests that this metric has the potential to quantitatively describe the bedform irregularity and its historical changes at the groyne field and natural channel.
