This Proceedings contains about 270 papers on a wide range of research topics on coastal sediment processes, including nearshore sediment transport and modeling, beach processes, shore protection and coastal managements, and coastal resilience building.The unique book provides a comprehensive documentation of cutting-edge research on coastal sediment process and morphodynamics from eminent researchers worldwide. Readers can learn the most current knowledge on numerous topics concerning coastal sediment processes and shore protection.

Large amounts of pollutants and natural disasters have been released into coastal and marine waters, wreaking havoc on the ecosystem and ecology. Pollution and habitat loss caused by humans have had and continue to have a significant impact on worldwide coastal and estuarine ecosystems. More than 80% of all marine pollution originates on land, with the majority of it coming from industrial, agricultural, and urban sources. Coastal and marine pollution is caused by human activities such as offshore oil and gas extraction and maritime oil transportation. Many of the world's estuaries and coastal zones are experiencing eutrophication, hypoxia, and other negative consequences as a result of anthropogenic activities. As a result, it's vital to avoid and regulate coastal and marine pollution, as well as build improved monitoring protocols and systems to aid in the understanding of spatial and temporal changes in coastal water quality. Recent technological advancements in coastal and marine seawater quality monitoring, such as real-time data collecting via data buoys, large-scale remote sensing intervention, automated data collection, and so on, are critical for comprehending real-time data and its influence on the environment.

World Congress on Disaster Management (WCDM) brings researchers, policy makers and practitioners from around the world in the same platform to discuss various challenging issues of disaster risk management, enhance understanding of risks and advance actions for reducing risks and building resilience to disasters. The fifth WCDM deliberates on three critical issues that pose the most serious challenges as well as hold the best possible promise of building resilience to disasters. These are Technology, Finance, and Capacity. WCDM has emerged as the largest global conference on disaster management outside the UN system. The fifth WCDM was attended by more than 2500 scientists, professionals, policy makers, practitioners all around the world despite the prevalence of pandemic.
