The coastline of Mohammedia is increasingly fragile. The dangers that threaten it are multiple: some beaches are deprived of their protective dunes used for construction, erosion, accelerated urbanisation, industrial and domestic waste, climate change, etc. To this is added the extension of the port jetty which caused a deviation of water currents, resulting in silting of the central beach and desilting of the Sablettes, Monica, and Manesman beaches.

A large part of the coastal shoreline is denatured by high tides. During the construction of the jetty, the impact of the infrastructure on sediment transport was neglected. The balance was broken, which contributed to a progressive degradation of the beaches and the developments surrounding the coastline.

For an environmental specialist, the dangers lurking on the coastline urgently require concrete actions to preserve the reputation of the beaches of Mohammedia: "Everyone is impatiently awaiting the implementation of legislation to protect coastal zones and restore balance".

To remedy the situation, numerous studies have been conducted in order to solve the problem and develop appropriate techniques to avoid the degradation of the coastline. "We are aware of the need for the protection of coastal zones. Among the solutions envisaged, the installation of breakwaters inside the sea to divert strong currents towards the 'Sablettes' and consequently attenuate the impact of the swell on the central beach," explains a communal official. The latter stresses that the project in question has not been realised. According to him, no new solution is programmed for the moment. The degradation of the coastline continues with all the risks that this entails. The problem of erosion represents not only a threat to tourism development, but also a strong attack on the sustainability of infrastructure, which implies from the services concerned an integrated management to preserve the coastline of Mohammedia. Let us recall that this coastline possesses a major tourist attraction and presents an ecological interest of primary importance and an economic interest. It constitutes a natural landscape heritage of great value. Some environmentalists in Mohammedia are, however, concerned about the impacts and hazards that jeopardise the constructions surrounding the sea.

"The most important thing today lies in a solution that takes into account the dangers lurking on the coastline. The services concerned are called upon for the protection of the beaches and the ecosystem of Mohammedia," affirms an environmental researcher. Hence the need to conduct in-depth studies taking into account all natural parameters (swell, currents, soil erosion,...) to provide solutions adapted to this phenomenon of continuous degradation of the coastline". Among these solutions, besides the installation of breakwaters inside the sea, the placement of tetrapods in the places most threatened by the effect of the waves can be envisaged.

The Minister of Energy, Mines, Water, and Environment, Fouad Douiri, has just presented during the government council of January 10, 2013, a draft law 81-12 relating to the coastline. This project, the discussion of which has been postponed, comes at the right time since it aims to fill a legal vacuum and give the competent authorities the necessary tools to overcome the anarchic practices threatening the entire coastline.
