The problems because of the frequent natural calamities like coastal erosion and flooding are becoming irresistible due to insufficient and inadequate embankment structures of Bangladesh. To date, the coastal zones of Bangladesh are often overpowered by floods, erosion, and intrusion of salinity due to shedding, poor and outdated designs of the laterite embankments. This study examines existing embankment solutions, identifying their deficiencies in design, construction, and maintenance, exacerbated by environmental and socio-economic challenges. To propose more effective coastal protection measures, this study analyzes the stability and economic viability of three different armor units: Traditional cubes, Tetrapods, and Accropodes. Stability analysis is done according to hydraulic stability coefficients, which shows the interlocking capability, as well as effectiveness of Tetrapods and Accropodes in comparison with the Traditional cubes. Furthermore, the economic consequences describe in detail about the expenditure incurred at every stage of the armor units, which involves material, construction, and maintenance cost factors. This study also includes the design enhancement of the better armor unit among those to make that eco-friendly. The study strongly suggests that, the introduction of these technologies will not only increase the board defenses of Bangladesh’s coastal infrastructure but also help reduce the effect of erosion and flooding at the coast.
