Figure 8:4 Hydromorphological effects occurring in the computational domain at the end of the simulation for Scenario 62, displayed as follows: (**a**) Plan view of shear velocities on the seabed, (**b**) plan view of suspended sediment concentrations, (**c**) plan view of flow velocities along the X-axis on the seabed, (**d**) plan view of morphological changes on the seabed. particularly at 2 m/s, where the floating object exhibited a greater proximity to the seabed. This effect demonstrated a direct relationship with towing speed, intensifying as speeds increased and diminishing as speeds decreased. The squat effect significantly influenced the flow dynamics beneath the floating object. Peak flow velocities were consistently observed beneath the bow section, with a gradual decrease in magnitude progressing towards the stern. This velocity gradient is attributed to the pressure differential created by the object's movement through the water. Figure 8:5 Distribution of suspended sediment concentrations across all scenarios. Figure 8:6 Comparative analysis of suspended sediment concentrations between blunt and raked bow configurations. Analysis of the model outputs for the blunt bow (Figures 5-8) revealed distinct hydrodynamic characteristics compared to the naked bow (Figures 9-12) configuration. The blunt bow geometry resulted in a more substantial displacement of water at the front of the object. This led to elevated water levels in the bow region, creating a pronounced pressure gradient between the high-pressure area at the bow and the low-pressure zone beneath the floating object. Consequently, this pressure differential induced higher flow velocities under the object. However, it is important to note that in certain operational conditions, the naked bow can also exhibit significant flow velocities and sediment resuspension depending on towing speed and clearance height. Figure 8:7 Sediment concentration according to various geometrical and hydrodynamic parameters for blunt and naked bow floating objects. An increase in the object's width, irrespective of bow shape, resulted in a greater volume of displaced water at the front. This amplified the instantaneous potential energy in this region compared to the baseline case. The heightened energy state translated into increased flow velocities beneath the floating object. Interestingly, increasing the object's length did not produce significant visual alterations in the flow patterns compared to the standard configuration. However, quantitative analysis of the numerical results indicated a slight reduction in flow velocities. This subtle effect warrants further investigation to fully understand the hydrodynamic implications of object elongation. The limited influence of object length on flow patterns can be attributed to the dominance of bow geometry, towing speed, and clearance height in shaping the hydrodynamic field. While length may play a role in certain scenarios, its effect is overshadowed by these more critical parameters, particularly in shallow water conditions where flow confinement and proximity to the seabed are pronounced. Following the analysis of flow dynamics, attention is now directed towards the morphodynamic effects and sediment suspension patterns observed in the numerical simulations. This comprehensive examination provides crucial insights into the complex interactions between floating objects and the seabed environment. At the conclusion of each scenario, the morphodynamic effects in the computational domain, flow velocities along the X-axis on the seabed, and shear velocities occurring on the seabed are presented in Figures 13-12. These figures provide a comprehensive visualization of the seabed interactions induced by the floating object under various conditions. Figures 13-16 illustrate the results for the floating object with a blunt bow, while Figures 17-20 depict the outcomes for the raked bow design. This comparative presentation enables a direct assessment of how bow geometry influences seabed interactions across different scenarios.
