Coastal regions around the world are undergoing significant changes due to a complex interplay of natural processes and human activities. The city of Mohammedia, located along the Atlantic Ocean coast of Morocco, is no exception to these coastal dynamics. This study presents a comprehensive analysis of the morphological evolution of the Mohammedia coastline from 1969 to 2023, focusing on shoreline erosion and the factors influencing these changes. the research identifies significant erosion along Monika Beach and Sablette Beach, reaching an alarming rate of approximately −2.15m per year between 1996 and 2023. Human activities, including urban expansion and port development, have played a central role in these coastal changes.

Coastal areas have become more exposed to natural hazards. Therefore, the management of coastal hazards is becoming more essential. Unfortunately, coastal hazards are often overlooked until their occurrence brings severe damage to the coastal areas. As more people develop their assets and properties in coastal areas, the impact from coastal hazard phenomena increases, such as the risk of potential hazards against coastal communities and properties as a result of sea level rise. The objectives of this paper are to evaluate and review the quality of the coastal hazard management plans that have been implemented in several countries. Developing advanced setbacks based on the need to avoid or reduce risk and accepting uncertainties can be established and translated into planning and management system in a pragmatic and effective way. An organization can learn from the success and failures, proving to be an effective approach that crosses functional boundaries. Best practices, new technologies and knowledge are to be transferred through this approach. The approach proposed in this study is the preparation of coastal hazard management for coastal communities through informed, coordinated and timely actions over long term. It is necessary to avoid an uncoordinated sectoral approach and locally incoherent mitigation countermeasures. From the lessons learned, it is important to follow appropriate and effective coastal hazard management cycle chart as a guidance for protecting the coastal area and the community.

The maturity of a scientific field can be measured by its capacity to formulate models. On this basis coastal modelling is in a mature stage with a range of models that have been developed and tested, both analytically and more importantly, in the field.

This article gives details of numerical packages that can hindcast the seastate, solve the wave and current fields around structures in the nearshore zone, make predictions about medium to long-term morphological developments, and predict the effects of storm attack on sandy beaches and dune systems. The models have an accepted mathematical basis and have been tested over a widerange of analytical and field situations.
