“…Mixed diurnal and semidiurnal tides appear at northwest and southwest end of the basin with an anticlockwise flow in the northern Gulf and a residence time of about 3.9 years. Other similar studies do exist for the Gulf hydrodynamics (Reynolds, 1993;Johns et al, 2003;Kampf and Sadrinasab, 2006;Yao and Johns, 2010;Alosairi, et al, 2011;Elhakeem et al, 2015;Peng andBradon, 2016 andIbrahim, 2017).…”

The study provides an assessment of sand dredging activities from the bottom of the sea during 2016 in the Kingdom of Bahrain. Total Suspended Solids were analyzed from 2010 until 2016 in the northern and eastern locations according to the Manual of oceanographic observations and pollutant analyses methods. Fifty five percent of sand dredging companies complied with some legislation such as air quality and occupational health. Almost all lacked any compliancy evidence supporting environmental protection. Only 9% of these sand companies use siltation processes to the dredged materials. Siltation is an important step to avoid dispersion of sand into the marine environment. Ambient Total Suspended Solids was around 6.1 mgl À1 ± Standard Error and the study recommends 10 mgl À1 level as an accepted concentration in samples taken from 500 meters away from the dredgers and 100 mgl À1 in samples taken from the middle of the generated silt plumes. The effect of climatic temperatures, dust storms and rain levels on seawater Total Suspended Solids concentration has been briefly discussed. The study concludes no significance seasonal or spatial variation on the ambient Total Suspended Solids concentration. It recommends coupling remote sensing with the conventional data collection and integration of modelling efforts for effective cost benefit monitoring and management of the coastal waters.

“…It has been applied throughout the world in coastal contexts similar to this one (e.g. Mulligan et al 2008Mulligan et al , 2010Garcia et al 2015;Hasan et al 2016;Peng and Bradon 2016;de Mendoza et al 2018;Rey and Mulligan 2021). Recent coupled Delft3D FLOW/SWAN configurations have also been successfully applied to this study region by Rautenbach (2020), de Vos et al (2021) and Rautenbach et al (2020b).…”

Table Bay, located in the Cape Peninsula region of South Africa, supports a variety of human and ecological interests. Notably it hosts a major port, with significant shipping and smaller maritime activity in and near the bay. Despite this, knowledge of its circulation dynamics remains cursory. In this study, surface gravity waves, particularly those with longer periods and higher wave heights such as swells, are shown to be important in driving near surface currents and establishing circulation patterns within Table Bay. A surface circulation feature, linked to large wave conditions and established by strong wave-driven flows near Robben Island, is identified and described by means of two coastal ocean model simulations. One simulation is dynamically coupled to a wave model and includes current forcing due to waves, whereas the other neglects waves. The influence of these wave-driven currents is relevant at the event scale, but also affects the monthly means of the simulation periods. Finally, the importance of including accurate surface gravity wave forcing in simulations of coastal currents, for applications of coastal models, is elucidated. This is achieved by analysing differences in the drift of a series of drogues deployed in the coupled and uncoupled simulations. Trajectories, drift speeds and drogue fates differed materially between the two configurations, underscoring the implications of wave-driven currents for common use cases.

“…Delft3D Flow has been extensively used in ocean and coastal domains [56] and the reliability of its code variously established [57][58][59]. The model has been successfully applied in cases similar to the one in this study (e.g., [48,50,53,60,61]).…”

A coupled numerical hydrodynamic model is presented for the Cape Peninsula region of South Africa. The model is intended to support a range of interdisciplinary coastal management and research applications, given the multifaceted socio-economic and ecological value of the study area. Calibration and validation are presented, with the model reproducing the mean circulation well. Maximum differences between modelled and measured mean surface current speeds and directions of 3.9 × 10−2 m s−1 and 20.7°, respectively, were produced near Cape Town, where current velocities are moderate. At other measurement sites, the model closely reproduces mean surface and near-bed current speeds and directions and outperforms a global model. In simulating sub-daily velocity variability, the model’s skill is moderate, and similar to that of a global model, where comparison is possible. It offers the distinct advantage of producing information where the global model cannot, however. Validation for temperature and salinity is provided, indicating promising performance. The model produces a range of expected dynamical features for the domain including upwelling and vertical current shear. Nuances in circulation patterns are revealed; specifically, the development of rotational flow patterns within False Bay is qualified and an eddy in Table Bay is identified.
