Submarine pipelines are the lifelines of the national economy. Under the influence of typhoons, high-speed currents and waves continuously erode the seabed, leading to suspension or even rupture of pipelines. Therefore, it is of great importance to study the sediment transport under the action of waves and currents. A numerical model of sediment scouring and deposition combining wave and currents is established, which considered tidal current, storm surges, wind waves, and sediments in the East China Sea. Combining with the monitoring of the actual laying condition of pipelines, it is found that the area with the most serious scouring is around KP300. It is shown that the typhoon weather with high intensity and density will lead to the suspension of pipelines, which is noteworthy in the construction of marine engineering.

Abstract Tropical cyclones and their associated impacts along the western and eastern Mexican coastlines have led to the recent announcement of the creation of a National Hurricane and Severe Storms Center in Mexico. While Mexico falls under the responsibility of the Regional Specialized Meteorological Center in Miami, the newly announced center aims to provide local warning advisories to local governments and emergency managers. This study developed their first operational tool, which provides rapid forecasts of hazard areas under the presence of waves and storm surges from tropical cyclones threatening Mexico. The tool is based on precomputed wave parameters and storm surges from 3,100 synthetic tropical cyclones. Maximum envelope maps for all of the events are stored in a system database that is accessed through a graphical interface. Using a search function of synthetic events, the user can select those events most analogous to the tropical cyclone in question in order to make an assessment of warning areas. The tool allows users to plot maximum envelope maps for individual events or maxima of maximum maps combining several events, either using precomputed values for the different parameters (wind, waves, and storm surge) or a normalized map. To demonstrate the capabilities of the operational tool, we present an example application based on Hurricane Patricia (2015). This tool could also be implemented by developing countries affected by tropical cyclones, which otherwise are often limited by numerical modeling capabilities, time, and budgets.

In this study of the evaluation of wave impacts on a gravity base structure (GBS) which is moored to berth No. 5 of the Centre of construction of large-capacity marine structures (CCLMS). It was identified five main wind directions that can be dangerous for the construction of CCLMS: East direction (E) South-East (SE) South direction (S), Southwest (SW), West (W) and Northwest (NW). According to the results of statistical processing of extreme storms of the 30-year period, two most dangerous directions of unrest were chosen-the Eastern direction (B) and the South-Eastern (SE) direction. Using a numerical model ARTEMIS, it was received wave field in the waters CCLMS near GBS reading for different sea levels. The simulation results showed that the wave heights affected the structure can reach 2.4 m.

Study Results

Tropical storms and storm surges are dangerous. The damage caused by them is very huge. Therefore, studying characteristics of storms and storm surges is of great interest today. This paper presents some study results on characteristics of tropical storms and storm surges, which landed in Vietnam during 1951-2015. These characteristics are determined based on the storm data collected on website of Japan Meteorological Agency, JMA. In the paper, the storm surges are calculated by a numerical model as TSIM 08 software. This softwave is established by the Institute of Mechanics, Vietnam Academy of Science and Technology. The numerical model has been calibrated and verified by measured storm surge data at the hydrographic, oceanographic stations along the Vietnam coast and the survey’s storm surge data in some storms.

Comparison Of The Results

In this work, the waves and currents generated by prognostic wind in the Sea of Azov are investigated using a three-dimensional nonlinear sigma-coordinate model. The mathematical model was also used for studying the transformation of passive admixture in the Sea of Azov, caused by the spatiotemporal variations in the fields of wind and atmospheric pressure, obtained from the prediction SKIRON model. Comparison of the results of numerical calculations and the data of field observations, obtained during the action of the wind on a number of hydrological stations was carried out. The evolutions of storm surges, velocities of currents and the characteristics of the pollution region at different levels of intensity of prognostic wind and stationary currents were found. The results of a comprehensive study allow reliably estimate modern ecological condition of offshore zones, develop predictive models of catastrophic water events and make science-based solutions to minimize the possible damage.

Taganrog Bay

Storm surges and wind waves are ones of the most important hydrological characteristics, which determine dynamics of the Sea of Azov. Extreme storm surges in Taganrog Bay and flooding in the Don Delta can be formed under the effect of strong western winds. In this work the sea level oscillations and wind waves in the Taganrog Bay were simulated by means of the coupled SWAN+ADCIRC numerical model, taking into account the flooding and drying mechanisms. The calculations were carried out on an unstructured mesh with high resolution. The wind and atmospheric pressure fields for the extreme storm from 20 to 28 of September, 2014 obtained from WRF regional atmospheric model were used as forcing. The analysis of simulation results showed the following. The western and northern parts of the Don Delta were the most flood-prone during the storm. The size of the flooded area of the Don Delta exceeded 50%. Interaction of storm surge and wind wave accelerated the flooding process, increased the size of the flooded area and led to the intensification of wind waves in the upper of Taganrog Bay due to the general rise of the sea level.
