“…India and Taiwan are also facing similar sediment supply in their beach recovery campaign. These areas are totally blocked from the hard structure such as groyne and the erosion is in one area and accretion in another area (Hsu et al, 2007;Vaidya et al, 2015). This present study also proved that there is high erosional intensity between the groyne and breakwater structure, especially at T3 (red box located at UMT beach in Figure 7).…”

“…Therefore, comprehensive studies to identify any impact of the hard structures on respective coastlines have to be carried out before implementing the combined programme. In India, Vaidya et al (2015) studied a series of breakwater and groyne impacts to the shoreline before any coastal planning had taken place. While in Thailand, Saengsupavanich (2013) and Prukpitikul et al (2018) made proper plans to use the breakwaters to reduce wave height before it moved to the coastline.…”

Since 2008, Kuala Nerus has undergone rapid urbanization along its coastline, resulting in the loss of sand along the littoral zone. Due to the heavy erosion in 2012 at Tok Jembal beach that migrated to Universiti Malaysia Terengganu (UMT) beach in 2013, the Department of Irrigation and Drainage has implemented a coastal defence project to mitigate erosion by building a series of ripraps/revetments along the coasts. Additionally, breakwaters and groyne structures were built in combination with beach nourishment programme. For the sustenance of the local fishermen community, the Malaysia Public Works Department replaced one of the breakwaters to a jetty-type breakwater at Tok Jembal beach. Shoreline evaluations, beach profile measurements and numerical modelling were used in this present study to identify the effectiveness of combining the coastal defence and beach nourishment programmes. The combination of programmes successfully initiated the accretion of a ~30 m beach dune and created new beaches. However, erosion remains persistent in the beach that was unprotected and exposed directly to the South China Sea. We posit that a combination of coastal defence and beach nourishment programmes can potentially interrupt dynamic coastal processes, especially the current parameters.

“…Besides the removal of large quantities of ocean sand, the APC project called for the construction of an offshore terminal composed of a three-kilometer caisson breakwater pier and two onekilometer jetties protecting the navigation canal. The results of this study indicate that over a three-year period following their completion, beach sediment accretion occurred on the up-drift side of these structures, accompanied by erosion on the down-drift side, conditions consistent with recognized sedimentation pattern changes resulting from barrier construction (Vaidya et al 2015). As Adrian Werner and colleagues (2013) and others have observed, coastal hydrogeologic processes are extremely complex, thus complicating attempts to identify controlling factors related to salinity.…”

Common-pool resources (CPRs) are subtractable resources that are physically or institutionally available for many users. The present study sought primary participant observation and focus group data on a Brazilian CPR-dependent community. It analyzes this data through the lens of CPR theory to assess ongoing local natural resource management efforts against longitudinal changes related to large-scale state and private development projects. The findings indicate that real or perceived changes related to the resources, technology, human populations, and decision-making processes in the study area have disrupted social arrangements and resulted in natural resource degradation. The article argues that, in order to achieve sustainability objectives, CPR-guided policy formulation must consider the social embeddedness of community-based actors and resources within their wider historical and social contexts, as well as user attitudes and relations among shifting conditions on multiple scales.

“…Shoreline location and its change in position are critical for understanding coastal structures [1], safe navigation [2,3], sustainable coastal resource management [4], and for flood protection and other risk management [5,6]. Furthermore, shoreline mapping and monitoring can help to understand the spatial distribution of coastal inundation including its trend over time.…”

Fuzzy Classification for Shoreline Change Monitoring in a Part of the Northern Coastal Area of Java, Indonesia

Abstract:This study presents an unsupervised fuzzy c-means classification (FCM) to observe the shoreline positions. We combined crisp and fuzzy methods for change detection. We addressed two perspectives of uncertainty: (1) uncertainty that is inherent to shoreline positions as observed from remote sensing images due to its continuous variation over time; and (2) the uncertainty of the change results propagating from object extraction and implementation of shoreline change detection method. Unsupervised FCM achieved the highest kappa (κ) value when threshold (t) was set at 0. 2013-2014 (65 ha). Urban development in flood-prone areas resulted in an increase of flood hazards including inundation and erosion leading to the changes of shoreline position. The proposed methods provided an effective way to present shoreline as a line and as a margin with fuzzy boundary and its associated change uncertainty. Shoreline mapping and monitoring is crucial to understand the spatial distribution of coastal inundation including its trend.
