Abstract:

 The coast of Dakhla is characterized by continuous dynamics as it represents a fragile and sensitive environmental system, which necessitates detailed study to better understand its transformations. Within this framework, the present study aims to diagnose the morphodynamic evolution of the Dakhla coastline through a diachronic analysis covering a 40-year period from 1985 to 2025. This period has been marked by increasing human pressures and intensified coastal development activities. The study adopted a sequential geospatial analysis methodology using remote sensing techniques and the Digital Shoreline Analysis System (DSAS) in order to statistically extract indicators of coastal dynamics, particularly Net Shoreline Movement (NSM) and End Point Rate (EPR). The findings reveal a fundamental transformation of the Dakhla shoreline. It shifted from a phase of natural dynamic stability between 1985 and 2005 to a phase of functional disturbance accompanied by a marked increase in the rate of coastal erosion. Data analysis indicates that the observed imbalance is primarily linked to shoreline hardening resulting from the construction of port breakwaters and urban expansion at the expense of the coastal zone. These concrete structures have acted as barriers to longshore sediment transport and have enhanced wave reflection processes, thereby exacerbating coastal erosion. These results raise significant concerns regarding current coastal development choices and highlight the need to reassess them while taking into account the sensitivity and fragility of the coastal environment, in order to promote flexible adaptation strategies rather than direct confrontation with natural dynamics.
