    Opis:
    High-resolution wind series in the southern Baltic Sea for the period of 1958–2007 are analysed to generate representative climate input conditions for a multi-scale morphodynamic model to simulate decadal-to-centennial coastline change. Four seasonal wind classes, each characterized by a predominant distribution of wind direction and speed, are derived from statistical analysis. Further calibration of this statistical description is done by sensitivity studies of the model to generate similar coastline changes of the Darss-Zingst peninsula as the measured data for the last century. The coastline change of this area is then projected for the next 300 years based on four different climate scenarios, through which impacts of accelerated sea level rise and storm frequency on the long-term coastline change are quantified.

    Rufisque
    Opis:
    This paper is aimed at analyzing the phenomenon of shoreline retreat in the locality of Rufisque from 1978 to 2018 mainly using geospatial data and field visits. A set of Landsat images from different dates at 10 year intervals was then acquired through the United States Geological Survey platform and shoreline change analysis was run using the Digital Shoreline Analysis System. In addition to that desktop work, interactions with local residents allowed the determination of ongoing adaptation strategies actually in place to cope with coastal erosion. The study showed that Rufisque is subject to serious rates of erosion reaching −19.48 m/year from 1978–1988, close to −8 m/year from 1988–1998, −5.88 m/year from 1998–2008 and −6.67 m/year from 2008–2018. Beside that coastal erosion, it has been noticed that the coastline also experienced in some of its parts cases of accretion reaching 4.94 m/year for 1988–1998, 7.29 m/year from 1998–2008 and 7.68 m/year during the period 2008–2018. In terms of surfaces, Rufisque’ shoreline respectively lost 156.81 ha (1978–1988), 80.55 ha (1988–1998), 6.94 ha (1998–2008), 12.93 ha (2008–2018) and in the same note gained 2.86 ha (1988–1998), 32.51 ha (1998–2008) and 19.16 ha (2008–2018) attesting to the fact that the coastline is subject to both spatiotemporal changes. Finally, this study also reveals that while authorities’ reaction is taking place at much lower pace, local communities are actually using their ingenuity to put in place strategies to tackle coastal erosion.

    Opis:
    There are many factors lead to coastline change, and coastal erosion by the sea-water can lead to the reduction of land areas. Meanwhile, with sedimentation, there will be an increase in landmass. Cirebon, which is part of the northern coastal area of West Java Province, is located on lowland with a dense population and rapid urban development. Several studies have been conducted during the past decade in the coastal areas of Cirebon with research results indicating that most of the coastal areas in Cirebon are subject to landslides at various scales ranging from vulnerable to bad conditions. Based on this, it is necessary to do a study aimed to know the time series trend of coastline change in Cirebon, Indonesia. This study is expected to provide valuable information on the latest conditions of coastal areas in Cirebon, and can be used as a basis for land use and coastal management planning, as areas of potential loss to erosion can be identified and future mitigation of the coastal areas can be undertaken. The configuration of changes in coastline was determined using remotely sensed data of Landsat 7 TM/ETM+ satellite. Imagery data was processed using MNDWI. Accordingly, Cirebon has for twenty years (1994-2014), experienced a significant shift in the coastline. The average value of the coastline advancing toward the sea is 643 meters and coastline setback is 343 meters, or there has been an average shift of the coastline of approximately 986 meters. Meanwhile, over the past twenty years, the length of the coastline has increased by around 2.2 kilometers. The value of coastline onward that is greater than the setback indicates that changes in the coastline in Cirebon tend to experience accretion. Conclusively, Cirebon’s coastline changes show an increasing trend in length and domination by the accretion (sedimentation) process.
