#### 4.1.4 Interpretation of Results
While the findings provide valuable insights into the effects of towing speed, object geometry, and clearance height, it is important to note that environmental variables such as water depth, current fluctuations, and sediment composition were not incorporated into this study. Including these variables in future research would provide a more comprehensive understanding of the factors driving sediment resuspension and improve the model's predictive capabilities. Future research should focus on addressing these limitations by expanding the dataset, incorporating additional environmental variables, and validating the model with empirical data. These efforts will contribute to the development of more accurate and reliable predictive models for sediment resuspension, thereby supporting sustainable design and operational practices in marine engineering. 5. Discussion  
The findings of this study underscore the profound influence of hydrodynamic parameters and floating object geometry on sediment resuspension in marine environments. The regression analysis revealed that the Froude number and squat ratio are paramount in determining the extent of sediment disturbance caused by non-powered floating objects. The significant positive correlation between the Froude number and sediment concentration corroborates the existing literature that identifies vessel speed as a critical factor influencing sediment dynamics in shallow waters. The squat ratio's positive association with sediment concentration highlights the role of object deformation in sediment dynamics. As the squat ratio increases, the floating object undergoes greater deformation, disrupting the water flow beneath and enhancing sediment suspension. This relationship emphasizes the necessity of optimizing floating object designs to minimize deformation under operational conditions, thereby reducing their environmental footprint. While phenomena such as the squat effect and width-velocity relationships have been extensively studied for powered vessels, the results demonstrate distinct characteristics in non-powered cases. The absence of propeller-induced turbulence leads to pressure-dominated flow fields, resulting in different patterns of sediment mobilization. Specifically, the squat effect in non-powered objects shows stronger dependence on geometric parameters, as the flow field is shaped primarily by the hull form rather than propulsion effects. This understanding extends existing hydrodynamic frameworks by characterizing these unique mechanisms in non-powered scenarios. Moreover, the study elucidates the differential impact of bow geometries on sediment resuspension. Raked bow designs were found to significantly mitigate sediment disturbance compared to blunt bows. This is attributed to the streamlined flow facilitated by raked bows, which reduces shear stresses and limits sediment mobilization. The negative coefficient for the interaction between the Froude number and object type further accentuates the efficacy of raked bows in moderating the effects of hydrodynamic forces on sediment dynamics. Overall, this study provides a quantitative framework for predicting sediment resuspension based on specific floating object characteristics (e.g., bow shape, dimensions) and operational parameters (e.g., towing speed, clearance height). The insights gleaned are instrumental for the design and operational planning of floating structures, enabling stakeholders to implement strategies that balance operational efficiency with environmental conservation.
