Tropical cyclones (TCs) play important roles in the evolution of beaches. The response beaches to a single tropical cyclone (TC) has been well reported, however, few studies have compared responses same beach TCs with different characteristics. Taking Haiyang Beach northern China Seas as case study, profiles before and after two TCs, Lekima Bavi, which passed through west east sides study area,...

A high-resolution coastal Finite-Volume Community Ocean Model (FVCOM) has been configured to simulate the water circulation in Eastern Shore Islands (ESI) archipelago on Scotian Shelf. Circulation this area is characterized by complex interactions between irregular coastline, a dense archipelago, tides, wind, and subtidal currents. outputs show close agreement with current, hydrographic observa...

Tidal duration asymmetry (TDA) in Zhoushan Archipelago (ZA), East China, was investigated with a three-dimensional hydrodynamic model based on the finite volume community ocean (FVCOM). The evaluated against observed sea surface elevations, currents, and harmonic constants, evaluation indicated that agreed well observations. As TDA is caused by high-frequency harmonics of main astronomical tide...

Abstract Generally, ports in the North American Great Lakes are not supported with navigational guidance (water level, water temperature, currents, ice) by NOAA’s Operational Forecast System (GLOFS). To examine benefit of extending model coverage to this critical infrastructure, a linked hydrologic-hydrodynamic framework was developed for Twin Ports Duluth-Superior western Lake Superior, and te...

در این مقاله به بررسی قابلیت های استفاده از روش همسان سازی داده ها  با استفاده از طرحواره  رانش  (واهلش نیوتنی ) روی مدل  FVCOM و با استفاده از داده های دمای سطح دریا (SST ) ماهواره AVHRR پرداخته شده است. همسان سازی داده ها فرآیندی است که داده های مشاهداتی را با مدل عددی به منظور بهینه سازی حالت مدل ترکیب می کند. این کار با تصحیح خطاهای مدل بر اساس داده های مشاهداتی به دو منظور صورت می گیرد: یک...

جزرومد به عنوان یکی از منظم ترین تغییرات سطح آب دریاها و اقیانوس‌ها محسوب می‌شود که به علت تأثیرگذاری بر الگوی جریان از اهمیت ویژه‌ای برخوردار است. نظر به نیازهای مهندسی و زیست محیطی در منطقه اقتصادی- صنعتی خلیج فارس، تنگه هرمز و دریای عمان، اطلاع از ویژگی‌های جزرومدی این مناطق دارای اهمیت است. برای این منظور از مدل اقیانوسی FVCOM استفاده شده تا دامنه جزرومدی در منطقه شامل خلیج فارس، تنگه هرمز،...

Marine oil spills occur suddenly and pose a serious threat to ecosystems in coastal waters. Oil continuously affect the ocean environment for years. In this study, spill caused by accident of Sanchi ship (2018) East China Sea was hindcast simulated using particle-tracing method. Sea-surface winds from European Centre Medium-Range Weather Forecasts (ECMWF), currents Finite-Volume Community Ocean...

Abstract The world’s largest lakes, including the Laurentian Great Lakes, have experienced significant surface warming and loss of ice cover over last several decades. Although changing conditions received substantial research interest, changes below remain largely unexplored, despite their importance for turbulent mixing, nutrient cycling, primary production. In this study, we investigate in s...

Understanding coastal circulation and how it may alter in the future is important island settings, especially South West Pacific, where communities rely heavily upon marine resources, sea level rise (SLR) higher than global average. In this study we explore use of an unstructured-mesh finite-volume modelling approach to assist filling knowledge gaps with respect remote locations—selecting Vanua...

Coastal ocean processes are complicated and they happen as various phenomena that span a vast range of spatial and temporal scales. For instance, general circulations of oceans occur at global scales (Wunsch & Ferrari, 2004). Tropical waves that eventually impact coastal waters propagate with wavelengths of one thousand kilometers and periods of one month (Legeckis et al., 1983). Langmuir cells...
