THE ROLE OF WOVEN GEOTEXTILE TUBE AS LOW-CRESTED BREAKWATERS IN RESTORING  SEVERE BEACH EROSION PROBLEM AT PEBUAHAN BEACH IN BALI ISLAND 


Pebuahan Beach in Jembrana Regency, Bali has skilled extreme seashore erosion when you consider that the building of the Nusantara Pengambengan fishing port, 10 km east of Pebuahan. Efforts to countermeasure the coastal trouble has been carried out through many neighborhood residents, however failed due to sturdy longshore drift. Through a collaboration between the Research Center for Water Resources, the Bali Penida River Basin, and PT. Geotechnical Systemindo, the implementation of low-crested breakwaters (LCB) or PEGAR, made of Woven Geotextile Tubes was once initiated. Four woven geotextile tubes C12.9 m with size different from 20 m to 25 m have been established to shape LCB with the size of 60 m, at distance to the coast of 50 m. The monitoring of shoreline modifications used to be carried out over the three months after its installation, which indicates the formation of a new shoreline with the quantity of deposited sand of 185.8 m3. The breaking wave on LCB crest effects in correctly controlling the longshore current, for this reason the longshore go with the flow settles at the back of the LCB to structure a new coastline. It is anticipated this subject find out about can be dealt with as an extra enter to enhance LCB Guideline and to extend LCB effectiveness scope no longer solely practice to shallow wave stipulations and seashores such as on North coast of Java, however additionally can be utilized extra universally to a deeper coastal waters with excessive wave conditions.
