• Resumen

  • The present paper characterizes the distribution of sediments and geo-forms in a tidal channel within the Guadiana River Mouth using Side Scan Sonar techniques. This work presents a map of bed distribution in terms of sedimentary lithology and geomorphological features. From a lithological point of view clean sands, muddy sands and sandy muds can be distinguished. From a dynamic perspective, each lithological type can present accumulative or erosional features. The dominant flow regime in the sandy beds can be deduced from the morphology and asymmetry of bedforms.
