Tsunami currents in ports.

Tsunami-induced currents present an obvious hazard to maritime activities and ports in particular. The historical record is replete with accounts from ship captains and harbour masters describing their fateful encounters with currents and surges caused by these destructive waves. Despite the well-known hazard, only since the trans-oceanic tsunamis of the early twenty-first century (2004, 2010 a...

Visualization of large-scale internal seiche in Lake Inawashiro

Field observation of water temperature in Lake Inawashiro has been carried out in 1999. Spatial variation of the temperature in the whole area of the lake can be obtained using a simple linear interpolation method, as seen in the figures. In Figs.1 and 2, strong wind from the left caused deepening of the interfacial layer on the right hand side. Subsequently, upwelling of cold water was observe...

Ports in a Storm

In many parts of the world, shipping-related emissions have already exceeded or are expected to soon exceed those from land-based sources. Shipping emissions can be reduced substantially by using some of the same technologies being applied to land-based sources, including cleaner engines and fuels, exhaust control methods, and operational modifications. Various ports are testing the feasibility...

Modeling Ship Arrivals in Ports

Ports provide jetty facilities for ships to load and unload their cargo. Since ship delays are costly, terminal operators attempt to minimize their number and duration. Here, simulation has proved to be a very suitable tool. However, in port simulation models, the impact of the arrival process of ships on the model outcomes tends to be underestimated. This article considers three arrival proces...
