This article proposes a method for plotting fairways using gradient fill of digital terrain models the bottom relief. The purpose is to improve accuracy fairway plotting, ensuring safety both manned and unmanned navigation. Non-regulated are usually plotted by eye. When done this way, placement directly depends on cartographer's capability initial data. Gradient allows operator instantly accura...

In recent years a great deal of research efforts in ship hydromechanics have been devoted to practical navigation problems in moving larger ships safely into existing harbors and inland waterways. An area of particular concern is the prediction of ship squat in shallow or restricted waters at different speeds. Squat may cause grounding of the ship which result in severe damage to the ship, and ...
