Calculation of Wave Inputs Required when Predicting Shoreline Erosion Caused by Vessels Operating in Inland Waterways

摘要

This paper is part of a research project titled Modelling wash -assessing fuel consumption and erosivity, which is financed by Trafikverket, Swedish Transport Administration. The project aims at developing a computational model to calculate the shoreline erosion caused by ships travelling in inland waterways. This paper covers a field study into possible linear methods which could be implemented to find the wave inputs required to predict shoreline erosion. Thin-ship theory was decided upon and implemented to calculate wave resistance and elevation. Results show the thin-ship model to be accurate for all tested ships between Froude numbers of 0.35-0.7. However, the model does under predict the wave resistance at Froude numbers below 0.35 for vessels with a transom stern.
