Special Issue Information

Dear Colleagues,

The main aim of this Special Issue is to provide a summary of the most recent research on coastal morphology changes. Coastal evolution is the result of a complex set of several dynamic and interacting processes, all working on a variety of time and spatial scales. The delicate balance of the coastal sediment budget can be reworked both by natural physical processes, such as the local ocean conditions or relative changes in sea level, and by human interventions, such as inland infrastructures, which reduce or block the riverine load to the coast, or coastal structures that alter sediment coastal transport. The main consequence of coastal dynamic changes is the increasing loss of beaches as a result of intensive erosional phenomena. Most of the world’s population lives in coastal areas and has over the last few decades experienced coastal hazards (erosion, flooding, etc.). The assessment of the entity of coastal evolution thus becomes vital to support the decision-making process in coastal management.

Studies focused on the following research topics will be welcomed:

  • Functioning of the coastal morphodynamics
  • Sediment budget assessment
  • Coastal changes over the long and medium term
  • Coastal management

Many tourists around the world are interested in coastal sites of exceptional scenic quality. This paper aims to assess the landscape quality of 50 sites along the Moroccan Mediterranean coast based on a novelty Coastal Scenic Quality Evaluation (CSQE) method able to classify the attractiveness of the sites and to distinguish exceptional ones with high tourist potential. This proposed methodology relies on evaluating coastal areas through easily obtainable indicators in order to simplify its application to other regions around the world. Four landscape dimensions were selected: Substratum, Sea-Coastal Area, Vegetation and Scenic Background. Each dimension was numerically assessed and ranged from 0 to 1. The values of each dimension along the sites were classified as: <0.2 (very low); 0.2 to <0.4 (low); 0.4 to <0.6 (medium); 0.6 to <0.8 (high) and ≥0.8 (very high). The results show that the overall scenic quality score of the Moroccan Mediterranean coast is 0.6 (high quality), reflecting a potential tourist destination of high scenic value. Substratum, Sea-Coastal Area and Vegetation dimensions obtained a high quality score (0.6 to <0.8), while the Scenic Background dimension recorded medium quality (0.4 to <0.6). Urbanization, the presence of litter and sewage evidence were the main factors of degradation of the Moroccan coastal landscapes, i.e., 32 out of 50 sites (64%) obtained low scores (from 0 to 2) for these three variables. Sound management actions have to be taken to reduce their impacts, in order to preserve and improve the natural landscape, and strength its capacity to host the various tourist activities.

Based on four years of spatially synchronous topographic data of the Oujiang Estuary from 2002 to 2019, the variations and physical mechanisms of estuarine evolution driven by natural conditions and human activities since the beginning of this century were analyzed. The results show that the evolution of the Oujiang Estuary has changed dramatically in the past 20 years. From 2002 to 2019, the net sediment erosion of the estuary was 163.44 million m3, and the average bed elevation of the river-dominated section (RDS), transition section (TS) and tide-dominated section (TDS) decreased by 4.61 m, 1.30 m and 2.14 m, respectively. In addition, the pattern of the shoal channel had changed, and the river facies coefficient (width–depth ratio) decreased by 16–64%. The evolution of the Oujiang Estuary is mainly caused by human activities (such as sand mining, reclamation). Sand mining is the direct cause of riverbed undercutting, and the large undercutting of riverbed terrain causes the increase in tidal power in the estuary and further causes river channel scouring. In the last 20 years, the average annual tidal range of the estuary increased by 0.19–1.14 m, and the flood discharge increased by about 17–80%, with an average value of 58%. The impact of tidal power on the evolution and development of the estuary has increased significantly. Apart from sand mining, reclamation projects such as the Wenzhou shoal outside the mouth also cause the local velocity of the tidal current section to increase, which aggravates the scouring trend of local river sections downstream. The scouring and silting changes in the Oujiang Estuary since the beginning of this century are the result of the adjustment of the estuarine system in response to the strong intervention of human activities.

Coastal dynamic is the complex result of multiple natural and human processes, and past and future coastal behavior studies become fundamental to support coastal zone management. However, the reliability of coastal evolution studies is strongly dependent on the analyzed time interval. The longer the period is, the more reliable the past shoreline change analysis and the forecast of shoreline position will be. The present study showed the 50-years shoreline evolution of the Catania coastal plain (Southern Italy), a densely populated area where human-induced processes profoundly changed natural dynamics. Landsat and Sentinel imageries were used to extract shorelines’ position over the time between 1972 and 2022 and the DSAS tool was used to calculate the shoreline change rates. The shoreline evolution in 2032 and 2042 was performed by the Kalman filter method, a tool largely applied to forecast short-term shoreline future position. Most of the Catania coastal plain was mainly retreating over the last decades. However, the most significant changes were registered in correspondence with the coastal structures and the river deltas. The reliability of the forecasting model was highly related to the coastal morphology. As such, the lower RMSE values were calculated in correspondence with the uniform coastal subsectors.
