Morphological Changes and Alterations in Erosion–Accretion Patterns in a Semiarid Brazilian River

Earth Surface Processes and Landforms, Volume 51, Issue 9, September 2026.
Flow regulation by the Castanhão Dam significantly altered discharge dynamics and reduced sediment transport in the Jaguaribe River. Long‐term analysis (1958–2025) reveals attenuated flood peaks, decreased channel migration and progressive downstream stabilisation, highlighting persistent geomorphic adjustments in a regulated semiarid fluvial system ...
