The Sanduao Bay is the bay with many of islands where the coastline is very winding with complex hydrodynamics and sediment transportation. Using a 2-D wave-current coupling hydrodynamic model of the Mike21 software package, the hydrodynamics condition on the Pingang Operation Area of Baima Port in the Sanduao Bay is simulatated. The results show that the current field in the berth is smooth that is beneficial to maintenance of water depth and reduction of siltation in berth. And the velocity in reclamation and dredging area is reduced less than 0.05m/s. the reclamation near the coastline and dredging in the berth make the velocity varied and the varying range is between 0.3m/s and 0.4m/s.

Hydrodynamic Factors

The offshore areas belong to the marine terrestrial interaction region. There are complex hydrodynamic factors, which influence each others and controlled transport of sediment and contaminant near shore. The paper builds up a wave-current coupling hydrodynamic model with Mike21 software package. After validation and calibration, the model is applied to wave and tidal current simulation on Zhuanghe fishing port project. The results show that the large area flow field is substantially unchanged after project construction and the effect is restricted to a small region near around the fishing port.

The Haikou Macun Port is the harbor located in the Chengmai Bay of the southern Qiongzhou Strait, China. The principle for the constructing harbor and waterway is the layout should be conformed to the current field. The layout planning port area is studied from the view of hydrodynamics with a wave-current coupling hydrodynamic model of the Mike21 software package. The results show that the large area flow field is substantially unchanged after project construction and the effect is restricted to a small region near around the Macun Port.

Abstract The spillway rating curve of the Riam Kiwa Dam was investigated via theoretical formula, laboratory experiment, and 3D numerical modeling. It is an ogee type with two uncontrolled and five gated spillways with a total length of 77.5 m. The experiment was performed with a scale of 1:50, while the numerical modeling was conducted using FLOW-3D software. Several discharge values (16.67–2,652.7 m3/s) were tested and observed for two different scenarios of gate openings. For the low discharge in Scenario 1, the theoretical formula and FLOW-3D computed the rating curve less accurately with the error values greater than 10%. A similar phenomenon was observed in Scenario 2, where both theoretical formula and FLOW-3D predicted the rating curve accurately with error values less than 10% for the higher discharge. The discharges tend to be overestimated for the water depth values greater than 2 m giving the average discharge deviation of 6% for the PMF condition. FLOW-3D was found to calculate water depth for all scenarios accurately. It shows a promising approach between numerical simulation and physical modeling, to minimize laboratory model construction costs.

Abstract Obtaining energy from tide currents in onshore locations is of great interest due to the proximity to the points of consumption. This opens the door to the feasibility of new installations based on hydrokinetic microturbines even in zones of moderate speed. In this context, the accuracy of energy predictions based on hydrodynamic models is of paramount importance. This research presents a high precision methodology based on a multidimensional hydrodynamic model that is used to study the energetic potential in estuaries. Moreover, it is able to estimate the flow variations caused by microturbine installations. The paper also shows the results obtained from the application of the methodology in a study of the Nalón river mouth (Asturias, Spain).

Hydrologic Condition

To ensure the secure buried depth of the subway tunnel which was routed underneath the Fenghuahe River, a two-dimensional tidal current and sediment transportation model was established to simulate the maximum scour depth of the riverbed. The conclusions were shown as follows: the most disadvantageous hydrologic condition was a combination of the 200-year return period flood in the Fenghuahe River and the 5-year highest tide in the Yonghe River. The maximum scour depth of the riverbed above the subway tunnel was 1.19 m and the lowest elevation of the riverbed cross-section was -8.56m. The results could provide technical support for the safety of subway design.

Based on the hydrodynamic model and wind field data, a multi-module coupled oil spill model is constructed for simulating the trajectory of oil movement. A case study is researched in Bohai Bay. The model works well and the numerical simulation results show the model is suitable for oil spill trajectory simulation. Two cases are considered with and without wind to show its important influence for the oil spill.
