Abstract
The present study aims to give a comprehensive account of the sedimentological characteristics and sedimentary processes action on Nile Delta coastal lagoon. The study carried out on 15 surficial sediments samples collected from Lake Burullus. Through a detailed sedimentary texture study and using applications (CM diagram, bivariate diagrams and multivariant linear discriminant functions) sediment source, transportation and accumulation of Lake Burullus are suggested. Results revealed that the increased coarse fractions northward near inlets were due to wave actions which indicate the high-energy transporting environments. Moreover, Areas of drains effluents, fine fractions are trapped and deposited directly after the entering of the lagoon, then it well-ordered by hydraulic sorting. Mean grain size is mostly controlled by sediments sources. Sediment sorting is mainly poor indicating turbulent conditions. Skewness results indicate that lagoon is classified as environments undergoing depositional trends spatially southward. The CM divulges that the deposition takes place by homogenous suspension and rolling. With strong freshwater processes signatures, turbidite deposition, and siltation are more than truncation in the main transportation mode.
