Shoreline Change with Groin Coastal Protection Structure at North Java Beach

Abstract

The research aimed to study the effect of groin application to erosion at the shoreline. The method utilized the bathymetry and topography data of north beach of Balongan, West Java. Modeling of the shoreline change due to groin installment used software called GENESIS. Based on analysis result, it is found that the significant wave direction comes from the southeast with significant wave height of 1,18 meters and surf zone width of 140 meters. It is concluded that at research area of north beach of west Java, I-groin with length of 70 meters and T head groin of 60 meters in long T-groin effectively overcome erosion and advance the coastline by 10786,62 m2 or in average 6,3 meters.

Numerical Analysis of Shoreline Changes along the Coast Batu Hiu-Bojong Salawe, Pangandaran Regency, West Java Province, Indonesia

“…Therefore, continuous research and monitoring of coastline dynamics are crucial to inform effective coastal policies and environmental conservation efforts. The following are some researchers conducting studies related to coastline changes in Java [9][10][11][12]. Study [9] examines the influence of groin application on erosion along the northern shoreline of Balongan, West Java.…”

Perencanaan Jetty di Pantai Bahagia Batam sebagai Upaya Pencegahan Abrasi Pantai

“…Berdasarkan hasil studi literatur mengenai penelitian yang telah dilakukan, perencanaan bangunan pantai menghasilkan output yang beragam. Output tersebut beragam seperti dengan dibangunnya groin dan revetment (Taqwa & Hariati, 2013) dapat menanggulangi dampak abrasi karena mampu mengubah kecepatan arus (Faza & Kurniadi, 2016;Hariati et al, 2021), groin dapat digunanan untuk mengurangi sedimentasi dan melindungi daerah garis pantai (Mamanua et al, 2017;Setyandito et al, 2020), revetment dengan balok beton bergigi dapat diterapkan untuk merehabilitasi di pantai Tegal Besar yang sebelumnya dilindungi oleh revetment tetapi telah mengalami kerusakan (Pujianiki et al, 2021). Untuk solusi dari masalah akresi Pantai Bahagia, output perencanaan bangunan yang digunakan adalah Jetty.…”

Placement of geotextile tubes as coastal management of way hawang seashore area at Bengkulu Province

“…Way Hawang coastal area is experiencing abrasions. Efforts to eliminate abrasion on the Way Hawang Coast are mostly carried out using coastal protective structures, including breakwater structures [8][9][10]. One of the breakwater structures that can reduce wave energy is geotextile tubes, which is a low-threshold breakwater structure.…”
