    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.

    The role and construction method of adding geotextile when paving asphalt on highway

    Geotextiles are widely used in highway road maintenance because of their ability to separate materials of different qualities. The isolation plays a role of load sharing or reinforcement. At the same time, it has high tensile strength, puncture resistance and burst resistance. Plays a major role. The addition of geotextile to asphalt pavement on highway pavement has three main functions, namely maintenance and repair of asphalt pavement; old pavement covering to prevent pavement reflection cracks and delay the occurrence and development of reflection cracks; providing highway roadbeds for treating soft soil foundations, Speed up the consolidation of the foundation and improve the bearing capacity of the subgrade.

    Standard Practice for Construction of Geogrid for Subgrade Engineering

    Construction process: Construction preparation (material transportation, setting out) → substrate treatment (cleaning) → geogrid laying (laying method, overlap width) → filler (method, particle size) → rolling geogrid → lower geogrid paving.

    First Council in Australia to Use a Bituminous Geomembrane (BGM) to Cap a Landfill Site for its Rehabilitation

    Townsville City Council is the first council in Australia to use a bituminous geomembrane to cap a landfill website for its rehabilitation. The $4 million venture is developing the closing cap on the last component of the Hervey Range landfill. The bituminous geomembrane is much less susceptible to leaks and is greater resilient than different products. Council’s Townsville Water and Waste Committee chairperson Councillor Russ Cook stated it had been interesting to see the assignment radically change the site.

    Lake Francis Dam maintenance with GCCM

    The Yuba Water Agency in Yuba County, Calif., was established in 1959 to reduce flood risk and provide a sustainable water supply to the people of the region. Yuba County has historically endured devastating floods, due in part to Gold Rush-era hydraulic mining practices that washed millions of cubic yards of debris into the Yuba River, raising the riverbed and increasing the flood risk.

    GSI to host webinar on lifetime predictions of geosynthetics

    A most frequently asked question regarding all types of geosynthetics is, “How long will they last?” This webinar answers the question for exposed geotextiles and geomembranes assuming that they were properly designed and installed. Furthermore, it compares these new exposed results to earlier lifetime prediction results on covered geomembranes.

    Strain Monitoring Strategy of Deformed Membrane Cover the use of Unmanned Aerial Vehicle‐Assisted 3D Photogrammetry

    Membrane covers are commonly used as floating covers for clean water reservoirs to prevent evaporation and pollution; for landfills to trap hazardous chemicals and unpleasant odour; and for tailing  impoundment  [1–3].  Floating  cover  materials  such  as  high‐density  polyethylene  (HDPE)  geomembranes are very durable, resistant to many different solvents, and have a high strength‐to‐density ratio, and if well‐designed, long service life (in decades) even in harsh environments [2,3]. The Western Treatment Plant (WTP) at Werribee, Victoria, Australia, installed two floating covers to assist with the anaerobic treatment of the raw sewage beneath them, leading to the production of methane‐rich  biogas,  see  Figure  1.
