Key parameters of the sediment surface morphodynamics in an estuary – An assessment of model solutions

Determination of denudation rates by the measurement of meteoric 10Be in Guadiana river sediment samples (Spain) by low-energy AMS

“…Large-scale geomorphological evolution of an estuarine system was simulated by means of a hybrid estuarine sedimentation model (HESM) applied to the Guadiana Estuary, in Southwest Iberia. The key controlling parameters of the model are bed friction (f), current velocity power of the erosion rate function (N), sea-level rise rate (Sampath and Boski, 2018) and estimations of river discharge (Sampath and Boski, 2016). The uncertainty of sediment infilling rate will mainly depend on the reconstructin of palaeovalley sea-level rise.…”

Impact of Anthropogenic Facilities on the Morphodynamic Evolution of an Estuarine System: The Case of Oum Er-Rbia Estuary (Azemmour, Morocco)

“…The evolution of the littoral system was mainly influenced by the closest dam location and by the dredging works, in addition to the regulation of the river flow by the installation of hydraulic facilities upstream.anthropogenic factors such as hydraulic facilities, engineering works of protection and rehabilitation, dredging, etc. [6][7][8][9][10].The bathymetry and the morphology of an intertidal plain and transversal section of a shallow bottom estuary cause a tide asymmetry that affects the flow duration, compared to the ebb time, and the celerity of the tide current [1,2,[10][11][12]. In coastal environments, the waves generate coastal currents that interact with incident waves and lead to the sediment transportation and the process is favored when the angle between the waves and the coastal line is significant [13][14][15][16].…”
