“…The model comprises a hydrostatic hydrodynamic module, various modules for turbulence and incorporates dynamic baroclinic effects from salinity and temperature differences [11]. Thus, the hydrodynamic module numerically solves the classic hydrostatic momentum and continuity equations in order to predict water level changes, circulation and transport driven by winds, waves, tides, river discharge or density forcing.…”

Over the years, the growing development of coastal areas urbanization has led to marine habitat loss and degradation. With the continuous increase in population and industrialization, coastal zones are facing several issues arising from the continued decline in the quality of water and sediments and the rapid deterioration of marine ecosystems. Shipping activities exacerbate such a situation, especially in the vicinity of harbors, which are often affected by stagnant and contaminated waters, containing organic as well as inorganic substances. In Italy, although the environmental legislation does not appropriately consider the port as a water body, specific actions are required in order to properly manage these basins. In this regard, a 3D numerical model is firstly performed to detect the hydrodynamic circulation and the water renewal within a port in the southern Adriatic coast of the Apulian region (South of Italy). Then, some configurations of a possible technical solution, i.e. a pumping system aimed at improving water quality, are modelled. Specifically, the system consists of a pump that draws water from areas with less water exchange and enters it into areas inside the port with lower hydrodynamic circulation. The different results, in terms of (i) number of sinks and sources, and (ii) their location, are compared to obtain the best technical solution that enhances the water renewal and then improves its quality. The study allows readers to identify methods for proper planning and management of such shallow sea areas with low water exchange and thus highly susceptible to accumulation of harmful substances in the water, that are ports.

“…The result of this comparison has often been positive, thereby it would seem profitable to join theoretical studies with both mathematical and experimental analyses. In this paragraph two practical applications of relative mathematical models will be briefly illustrated, already seen elsewhere (Malcangio & Petrillo, 2009;Malcangio & Petrillo, 2010), both carried out at the Department of Water Engineering and Chemistry at the Technical University of Bari, Italy. Both the area under investigation are environmentally vulnerable because of their dryness and lack of natural watercourses.…”

“…The results of the simulations allowed the authors to conclude that between the two simulated project hypotheses for the outfall pipe length (605m and 770m), the best choice would be that of the shorter pipe taking into account both environmental and economic considerations. As second test case, the authors analyzed the optimal site for an outfall pipe originating from a seawater desalination plant in Bari, South Italy, at the planning stage (Malcangio & Petrillo, 2010). As in the previous case, the study focused on the dilution of the system brine discharge in the sea determined by a punctual salt source, considering the salinity as a tracer in recognizing the brine discharge path.…”

“…Therefore, mathematical modeling coupled with observations for verification and calibration is essential in such cases. Hydrodynamic and water quality models have been widely developed and used for the investigations of rivers [1][2][3][4], lakes or reservoirs [5][6][7][8][9][10][11], estuaries [12,13], and coastal waters [14,15] on various aspects. These models have been effective tools for explaining, simulating, and forecasting the complex processes in water environment.…”

This chapter introduces basic concepts, properties, and principles of different processes in inland surface water and analytical methodologies. The fundamentals of surface water hydrodynamics, including water properties, hydrodynamic processes, Cartesian coordinatebased governing equations, and boundary and initial conditions were reviewed. The fate and transport of contaminants in surface water were introduced. Based on aforementioned theory and principles, two hydrodynamic-water quality models were developed for studying a lake and a river, respectively. A stratified 3D model was used to investigate the circulation and E. coli transport in the nearshore region of Lake Michigan. The modeling results show that stratified phenomenon exists in the near region, and a 3D model is necessary even though a previous 2D model works well for the shallow water environment. A 2D depth-averaged water quality model was developed to estimate the fate and transport of four contaminants in the San Joaquin River of California. The modeling results indicate that it took 20 days for these contaminants to transport from the upstream to the downstream in the research domain. These models can be effectively used for inland surface water restoration and management.
