The Malaga Basin is located in the Internal Zone of the Western Betic Chain, southern Spain. The river channel is divided into 5 reaches from the mouth, according to the strike variations of the valley. The sinuosity decreases dramatically in reach 2 in comparison to the sinuosity in reaches 5, 4, and 3. We interpret this lower sinuosity in reach 2 as a decrease in the slope of the valley. This fact is also observed in the longitudinal profile of the river channel along reach 2. We conclude that the anomalies observed in reach 2 are due to a gentle syncline related to the active anticline of Sierra de Cártama.spajournal articlehttp://www.sociedadgeologica.es/publicaciones_geotemas.htmlopen access551.2Active foldingBetic ChainCuadalhorce RiverMalaga BasinRiver sinuosityGeodinámica2507 Geofísica
