This study utilizes a combination of GCM-RCM models and the HEC-RAS model to assess effects climate change on sediment transport dredging costs. Under RCP4.5 RCP8.5 scenarios for period 2049-2065, yield is projected rise by 13.2% 18.5% respectively, with general increase in most months but decrease June July. Results demonstrated that as volume increases, costs accordingly. It predicted will from $125,000 $160,000 between 2025 2045, aligning historical trend escalating expenses due accumulation. Furthermore, volumetric analysis current proposed cross-sections reveals magnitude deposition associated changes. The identifies an annual rate 6032.3 m³ estimates filling designated range 2069 require 244,690 deposition.
