“…Based on the data of exchanged water body volume, the box model method was adopted to calculate the environmental capacity in accordance with the physical change of pollutants in the water body and indicate the physical diffusion ability of the water body. Delft 3D (numerical simulation software) was employed to create a hydrodynamic force model of the tide and simulate the tidal field of Haizhou Bay [36][37][38][39].…”

Haizhou Bay is an open bay located in northern Jiangsu Province, China. This study analyzes the changes in the coastline, coastal development, and water quality of Haizhou Bay between 2006 and 2016. The box model method and numerical simulation are adopted to calculate the environmental capacities of Haizhou Bay in 2006 and 2016, analyze changes to environmental capacity features, and assess the influencing factors over this period. The scenario analysis method is used to discuss the influencing mechanism and degree of influence of factors (e.g., the water quality difference inside and outside the bay, and sea reclamation) on the environmental capacity and calculate the contribution of each influencing factor. The changes in terrain triggered by sea reclamation and water quality from 2006 to 2016 reduced the total environmental capacity of Haizhou Bay, with an influencing ratio of 0.198:0.802. In other words, poorer water quality inside the bay reduces the environmental capacity by a degree of 4.05 times that of sea reclamation. This study can offer guidance on related future research aiming to protect the marine environment of Haizhou Bay and control the total amount of pollutants discharged into the sea.

To calculate the environmental capacity of the estuaries of Haizhou Bay in northern Jiangsu, China in 2006 and 2016, this study employed the share ratio approach and established a tidal hydrodynamic model and a water quality diffusion model by the Delft 3D software to perform the numerical simulation. The article compared the environmental capacity in 2006 and 2016, and analyzed the changes between these years. The scenario analysis method was used to explore the influence of factors on the environmental capacity and quantify the contribution of each influencing factor. The results show that the theoretical environmental capacity was reduced by 32.718 tons/day (28.56%) from 114.571 tons/day in 2006 to 81.853 tons/day in 2016. The remaining environmental capacity was reduced by 6.955 tons/day (56.92%) from 12.219 tons/day in 2006 to 5.264 tons/day in 2016. The changes in topography and the amount of runoff into the ocean through the estuaries of Haizhou Bay between 2006 and 2016 reduced the total environmental capacity of the estuaries by an influence ratio of 0.363:0.637. The study will provide the management of the marine environment of Haizhou Bay with information to control the aggregate pollutants flowing into the ocean and support the social and economic sustainable development of Haizhou Bay.

“…This study aims to understand the physical interactions of various near-shore processes and simulate the hydrodynamic environment of the near-shore region of the North Goa coast, using Delft3D software. Many researchers worldwide have successfully implemented Delft3D to study various coastal processes (Elias et al 2001;Luijendijk 2001;Van Rijn and Walstra 2003;Treffers 2008;Rueda et al 2020aRueda et al , 2020b. The wave, tidal and current information are equally useful in designing various coastal development including recreational activities, construction of coastal protection measures, etc.…”

Investigation of near-shore processes along North Goa beaches: A study based on field observations and numerical modelling

The dynamic coastal environment comprising of near-shore zone and beach continuously undergoes substantial morphological changes due to man-made and natural processes. These processes are always mutually dependent and therefore understanding their physical mechanisms is complicated. In this study, an attempt has been made to understand the physical interactions between the waves, tides and currents in the near-shore regions of four major tourist beaches of Goa using Beld measurements and numerical modelling. The state-of-the-art instruments were deployed at 6 m water depth, for a fortnight at each beach for two seasons in 2018. In-situ depth data were collected along the 8 km stretch covering Baga to Sinquerim using a mechanised boat equipped with an Echo sounder and a differential global positioning system. A coupled Delft3D model was set up with the model domain created using in-situ bathymetry soundings, beach proBles' elevation and naval hydrographic chart data. Model simulations were performed for two seasons (Jan-Feb) for calibration and (Oct-Nov) for validation by forcing the FLOW and WAVE models with timevarying water levels obtained from the TOPEX/POSEIDON global tide model, wave parameters from European Centre for Medium-range Weather Forecasting data and the measured wind data. The model results were validated by comparing the significant wave height, current speed and water level with the insitu data. From these experiments, it has been observed that near-shore parameters change significantly with the season and are mutually interactive. Especially, the near-shore currents are varying according to the wave heights and water level variations (due to tides). The Delft3D model is capable of addressing the near-shore processes with a good level of accuracy. However, Bne-tuning the model parameters with more seasonal data would help in addressing several coastal processes for any future datasets and therefore could be utilised for investigating and forecasting near-shore processes.
