Analysis of Squat Effect in Shallow River for Inland Ferry

ABSTRACT: The squat determination during ships movement on restricted water areas is one of the most important problems affecting navigational safety. Precise squat prediction is essential to minimize the risk of grounding for ships. In Poland we have about 60 operated ferry crossing, part of them are base of transport infrastructure. The Lower Vistula River in Poland is a clear example of a shallow river. Zones of active sediment transport of sandy material are big problem in navigation conditions maintenance on this river. The paper presents an analysis of squat phenomena of ferry “Flisak” by empirical method and fluid dynamic in different conditions. The results of this research could be helpful for inland transport management, risk assessment of ferry crossing the Vistula River, and analysis for a new waterway project.
