Abstract

Bangladesh’s vital water transportation routes, like the MAWA to ARICHA corridor spanning 70.50 kilometers, are essential for the nation’s economic well-being. However, the deposition of sediment every year along this route poses a significant challenge for navigability. This study aims to analyze sedimentation characteristics, patterns, estimate sediment quantities, and develop a comprehensive dredging plan to remove this sediment for sustainable waterway management. In order to do this, first data for dredging related of this route were collected from the Bangladesh Inland Water Transport Authority (BIWTA) for the years 2019 and 2021, which later supplemented with information from the US Geological Survey (USGS) website. Using Geographic Information System (GIS) tools, particularly ArcGIS, this route was model, using data visualization technique, creating detailed route maps, highlighting water depth variations over the two years. From the model analysis volume sediment was calculated. The amount of volume sediment was found to be 3.03x105 cubic meters and compared with available published sedimentation rate and found satisfactory. This enabled to estimate the annual quantity of dredged material. Subsequently, some studies were performed to choose suitable dredgers and pumps, considering dredging capacity and efficiency. Based on sediment quantities, a 16 inch cutter suction dredger was selected and furthermore an optimal dredging plan was proposed. The proposed dredging plan was consideded based on the sedimentation rate, dredger capacity, and pump flow rate, which ensures efficient removal of accumulated material, preserving the route’s navigability and economic significance. The research yields invaluable insights into sedimentation rates and dredge quantities for the MAWA to ARICHA route. Based on the conducted study, several decision-making can be applied in other waterway managements. Moreover, the proposed dredging plan can serve as a model for other routes, contributing to navigability and regional economic prosperity.
