Summary: A computational model was used to study the impact of saltmarsh vegetation on tidal dynamics and residual currents in three different estuaries in Wales, UK. The results showed that saltmarsh vegetation reduced the amplitude of tidal constituents and affected the wider estuarine hydrodynamics, particularly in the middle and upper estuary. Changes to marsh vegetation had the potential to alter sediment transport and overall estuary dynamics.

Summary: This study assessed the spatio-temporal variability of evaporation rates on the water surface of Pentecoste reservoir in the Brazilian semiarid region using both the Delft3D model and remote sensing technique. The results showed that the Delft3D model accurately reproduced the water level variability and thermal structure of the reservoir. The study's innovative approach can help optimize the location of evaporation structures and improve water availability.

Summary: Tidal inundation, morphology of estuaries, and friction across intertidal surfaces influence tidal propagation and are affected by sea-level rise. Integrated eco-morphodynamic modelling approaches can help understand the responses of estuarine intertidal vegetation to sea-level rise. The study shows that wetlands can withstand modest sea-level rise rates through sedimentation, but may submerge under fast rates, highlighting the importance of considering eco-geomorphological feedbacks in predicting wetland response to sea-level rise.

Summary: This study analyzed sedimentological evidence from southwest Wales to assess the impacts of high magnitude coastal storms in vulnerable coastal saltmarshes. The results showed that major depositional events were relatively rare between 1929 and 2019, with three episodes of high magnitude saltmarsh storm surge deposition identified in 1954, 1977, and 1981. Further research is needed to explore the sedimentological storm impacts and sustain the vulnerable coastal saltmarsh environments.

Summary: As climate-driven risks increase for coastlines, understanding and predicting morphological changes and developing efficient coastal forecast systems have become extremely important for climate change adaptation. This article explores the potential of Artificial Intelligence and statistical models, specifically Artificial Neural Networks and Bayesian Networks, in predicting coastal morphological changes and sediment transport. The results show that these models have high regression values, indicating their potential for coastal applications.

Summary: Aquaculture has evolved rapidly in response to increased human demand for seafood products, leading to a threat to natural stocks. Portugal, with high seafood consumption, has been exploring its coastal systems to improve fish and bivalve cultivation. This study proposes the use of a numerical model to assess the impact of climate change on aquaculture site selection in a temperate estuarine system.

Summary: This study uses data analysis and idealized hydrodynamic models to investigate the effect of sea level rise and varying river inflows on estuarine tidal dynamics. The results show that estuaries with large riverine inflows and macrotidal conditions experience spatially heterogenous changes in tidal range, current velocity, and asymmetry. Short-to-moderate-length, high convergent estuaries show the greatest variations, while short-to-moderate-length prismatic and low convergent estuaries show the least variations. Transects near the estuary mouth and at a three-quarter estuary length are identified as the most and least vulnerable zones, respectively.

Summary: This study simulated the complete annual dynamics of fine-grained sediment in Lake Turkana, one of the world's large lakes, using the Delft3D model. The model successfully validated the simulation results and found that wind-waves can be the main agent in transporting sediment away from river mouths to deeper areas.

Summary: The study found that wind significantly influences the transport of floating plastics in coastal waters, and the model predicted that plastic waste can swiftly move seaward under specific wind conditions in Singapore. Climate change and increasing plastic usage will exacerbate plastic pollution and accelerate its spread.

Summary: Estimating the economic value of ecosystem services derived from estuarine habitats is important for prioritising management, conservation, and restoration activities. A novel approach using Bayesian stable isotope mixing models has been developed to estimate the value of estuarine habitats for commercially harvested species, but the difficulty of separating primary nutrient sources in estuaries with saltmarsh and seagrasses has limited its application. This study extends the approach and uses tri-variate isotopic composition to model the economic value of saltmarsh, seagrass, and other producer groups in a commercial fishery. The results highlight the impact of areal coverage on the comparative value of estuarine habitats, suggesting that habitats with higher proportional contribution to exploited species' diets may be of higher priority for conservation or repair.

Summary: This research aims to analyze and model the relationship between binomial rainfall and groundwater levels. It uses Bayesian Causal Reasoning (BCR) based on Bayesian Theorem to capture the inherent causality in the data. The methodology includes classic regression analysis and Bayesian Causal Modelling Translation (BCMT) with iterative steps. This innovative methodology has been successfully applied to aquifer management in the Campo de Cartagena groundwater body in Spain.

Summary: This study focuses on the overtopping characteristics of coastal seawalls under random bimodal waves, finding that existing prediction methods provide less accurate guidance for bimodal conditions. A modification to the EurOtop formula is proposed based on experimental results to better capture overtopping discharge under bimodal conditions.

Summary: Coastal vegetation plays a vital role in coastal defence by dampening incoming waves. However, current wave damping models struggle to balance accuracy and computational costs, often relying on plant-specific calibration of the drag coefficient. Experimental evidence suggests that wave damping by quasi-flexible cylindrical vegetation is controlled by the relative velocity between water and vegetation.

Summary: The study shows that saltmarshes can reduce flooding in estuaries during storms of varying intensity, with an average reduction of flood extents by 35% and damages by 37% for the largest 100-year storms. Wetlands save an average of $2.7 million in damages per estuary annually, surpassing the annualized value of better studied wetland services such as carbon storage.

Summary: Habitat suitability modelling (HSM) is increasingly used for decision making in conservation management and restoration efforts in oceans. This study used high-resolution Delft-3D modelled wave height data to improve HSM outputs for predicting suitable areas for seagrass growth. The findings revealed significant differences in fine-scale predictions and highlighted the increased importance of wave energy as a predictor variable compared to low resolution data.

Summary: In this study, numerical errors and instabilities in the interfacial region are investigated, and a new algorithm with strong temporal coupling and momentum-based velocity reconstruction is proposed to enhance its conservation properties. The capability of the proposed algorithm is demonstrated with two idealized cases and one laboratory dambreak case, showing advantages in the conservation of mass, momentum, energy, and mitigation of unphysical interfacial transport.

Summary: This paper investigates compound flooding in northern Jakarta, Indonesia, through the combination of coastal and river models. The results show that low-lying areas around the river inlet are prone to flooding even during regular storm events, and rarer storms cause extensive floods. The study also predicts that sea level rise combined with land subsidence will lead to the inundation of existing coastal flood defences during storms in the future, making upgrades necessary to prevent extensive flooding in Jakarta.
