## 1 Introduction
[8] found that in the Venice Lagoon, heavy ship traffic increased sediment suspension times up to one hour, despite typically short suspension durations in such environments. This prolonged suspension can have detrimental effects on water quality and aquatic life, indicating the broader ecological implications of vessel-induced sediment resuspension. [PERSON] et al. [9] investigated shoreline changes in the Malamocco-Marghera Canal in the Venice Lagoon, based on field measurements and satellite imagery analyses. They determined that one of the most significant causes of erosion along the shoreline was the hydrodynamic effects generated by heavy ship traffic, leading to an annual shoreline retreat of 3-4 m. [PERSON] al. [10] extensively examined the effects of vessels on riverbanks and protections, as well as shoreline changes in the Meuse River in the Netherlands. Using advanced measurement techniques, they provided detailed insights into how vessel-induced hydrodynamic forces contribute to bank erosion and morphological alterations. [PERSON] and [PERSON] [11] conducted field measurements in the Grand Canal, a heavily trafficked waterway in China's Jiangsu region, analyzing ship-induced wave and current data. Their findings highlighted that bed flow velocities increased significantly due to ship traffic, with single ship passages increasing bed flow velocity up to nine times compared to conditions without ship passage. To address the gaps in understanding the complex interactions between floating objects and sediment dynamics, some studies have employed advanced modeling and experimental techniques. For example, [PERSON] et al. [12; 13] utilized three-dimensional numerical models to examine suspended sediment concentrations resulting from hydrodynamic effects caused by ships with and without propellers. Their work provided insights into the compounding effects of ship-generated waves and propeller action on sediment resuspension in confined shipping channels. [PERSON] et al. [14] performed experimental towing tests and numerical modeling using inland water convoys, analyzing the influence of channel width, water depth, and ship draft on ship resistance and sediment movement. Their analyses showed that smaller channel widths, shallower water depths, and greater ship drafts significantly increased ship resistance, which can, in turn, affect sediment resuspension patterns. Physical modeling studies have also contributed to this understanding. [PERSON] [15] conducted physical model tests to investigate the forces on ships and the flow velocities and pressures on the seabed during ship movement. The experiments revealed that the most critical parameters affecting flow velocities under the ship were the shape of the ship's bow and the clearance between the ship and the seabed. Similarly, [PERSON] et al. [16] carried out full-scale physical experiments using a deeply loaded barge in the Juliana Canal in the Netherlands. They observed significant erosion in the canal bed, with gravel in the middle of the canal moving towards the sides after each passage, highlighting the impact of vessel movement on bed stability. The reviewed literature predominantly focuses on powered vessels, where propeller-induced turbulence and engine thrust dominate the sediment transport mechanisms. Non-powered floating objects, however, represent a distinctly different case where pressure gradients, wake patterns, and flow regimes arise solely from object geometry and movement characteristics. This fundamental difference in hydrodynamic mechanisms necessitates dedicated investigation, as existing theoretical frameworks developed for powered vessels cannot be directly applied. The preceding review demonstrates that while vessel-induced sediment dynamics have been extensively studied, the unique interactions between geometric parameters (bow shape, width, length) and operational conditions (towing speed, clearance height) in non-powered objects create distinct flow patterns and sediment transport mechanisms that require systematic investigation.
