Abstract


This paper explores the impact of discrepancies between Tide Gauge and RTK (RealTime Kinematic) Tide information on dredging computations in hydrographic surveys. The research focuses on cases where an average discrepancy of 10 cm exists between the two tide measurement sources. There are differences of 0.037 cm between them at a distance of 1 km from the base station, and these differences quickly increase as we sail further away from the base station, exceeding our expectations by about 0.139 cm at a distance of 10 km. The study aims to highlight how an average of 10 cm difference between Tide Gauge and RTK Tide measurements affects the accuracy of dredging computations. The results shed light on how such discrepancies can impact the accuracy and reliability of dredging computations, influencing navigational safety and operational efficiency in maritime settings. The research underscores the necessity of minimizing these discrepancies and proposes potential strategies to mitigate their influence on dredging computations. The study contributes significant insights for improving the accuracy of dredging calculations and enhancing navigational safety and operational efficiency in maritime settings.
