Assessing the Current Alterations to the Estuarine Ecosystem in Southwest Nigeria

Journal of Geography, Environment and Earth Science International, 2022
The estuarine ecosystem provides services that are economically and ecologically indispensable, and these services offer support to human well-being. However, uncontrolled human activities have altered the ecosystem goods and services provision, thus resulting in numerous irreversible ecological losses in the wetlands.

Breaking of internal solitary waves generated by an estuarine gravity current [PDF]

Geophysical Research Letters, 2017
AbstractMooring and ship‐based data collected in a stratified estuary showed the generation of internal solitary waves by a bottom gravity current. Down‐estuary winds drove a counterclockwise lateral circulation over channel‐shoal bathymetry. When the lateral flows became supercritical, the pycnocline was sharply raised at the edge of the deep channel,

NUMERICAL MODELING AS SUPPORTING TOOL FOR AQUACULTURE OF OYSTERS IN A SUBTROPICAL ESTUARINE ECOSYSTEM

Boletim do Instituto de Pesca, 2019
The Estuarine-Lagoon Complex of Cananeia-Iguape (ELCCI) is a large estuarine system dominated by mangroves, located on the southeast coast of Brazil (25° S, 48° W). Oyster farming is an important economic activity in Cananeia due to the natural abundance

Control of Source‐To‐Sink Processes on the Dispersal, Fractionation, and Deposition of Magnetic Minerals in a Tropical Mesotidal Estuarine System

Geochemistry, Geophysics, Geosystems, 2023
This study aims to elucidate the control of source‐to‐sink processes on the sediment dynamics of a complex mesotidal tropical estuarine system using rock magnetic, sedimentological, mineralogical, and geochemical methods.

A framework for estuarine future sea-level scenarios: Response of the industrialised Elbe estuary to projected mean sea level rise and internal variability

Frontiers in Marine Science, 2023
In this study, we apply probabilistic estimates of mean sea level (MSL) rise and a sub-set of regional climate model ensemble simulations to force a numerical model of the southern North Sea, downscaling projected sea level variability to the Elbe ...

Sampling Methods for Metocean Data Aiming at Hydrodynamic Modeling of Estuarine and Coastal Areas

Sensors, 2020
Field observations require adequate metocean data gathering to promote the link between environmental diagnostic and prognostic obtained from modeling techniques. In general, model confidence can be improved by using data which present better quality and

Effects of river discharge and wave forcing on hydrodynamics in a seasonal dual-inlet estuary

Frontiers in Marine Science
This study employs the Delft3D coupled wave-current model to investigate the spatiotemporal variability of flow and salinity fields, and the mechanisms governing residual currents under varying runoff and wave conditions in an estuarine area on the ...

Implementation and comparison of the recent three-dimensional radiation stress theory and vortex-force formalism in an unstructured-grid coastal circulation model [PDF]

, 2020
Given the importance of wave-current interaction in estuarine and coastal dynamics, it is crucial to revisit impacts of surface gravity waves on three-dimensional (3D) nearshore circulation.
