Wilayah pantai merupakan daerah yang sangat intensif dimanfaatkan untuk kegiatan dan aktifitas manusia. Adanya berbagai kegiatan tersebut dapat menimbulkan peningkatan kebutuhan akan lahan serta sarana dan prasarana yang selanjutnya akan menimbulkan masalah-masalah seperti erosi pantai yang dapat merusak kawasan pemukiman dan prasarana kota yang berupa mundurnya garis pantai. Salah satu penanganan yang dapat dilakukan yaitu membangun bangunan pelindung pantai seperti breakwater. Pemecah gelombang breakwater adalah prasarana yang dibangun untuk memecah gelombang dengan menyerap sebagian gelombang. Breakwater juga berperan sebagai penenang gelombang sehingga kapal dapat berlabuh di pelabuhan dengan lebih mudah dan cepat. Oleh sebab itu, untuk mengetahui respon struktur A-jack sebagai pemecah gelombang yang layak di tempatkan di PulauGusung terlebih dahulu memperhitungkan beban gelombang dan energi gelombang yang terjadi beserta stabilitas breakwater armour A-jack dengan menggunakan beberapa formula empirik. Besar energi gelombang yang dihasilkan yaitu 375,71 N/m atau 38,3119 kg/ / (0,0383 ton/meter), beban angin sebesar 25,878 ton/m dengan total gaya vertikal dan horizontal yang terjadi pada bangunan sebesar ∑ = 384,172 t/m, ∑H =89,5 ton/m maka, nilai kontrol stabilitas breakwater tehadap stabilitas Geser = 1,53≥1,25(Memenuhi). Setelah menghitung beban gelombang, selanjutnya beban gelombang diinput untuk mengetahui berapa tegangan yang terjadi pada struktur, dengan menggunakan software SAP 2000 menampilkan nilai kekakuan pada kaki struktur sebesar 9.000E-04 kgf/m dan tegangan terjadi pada struktur sebesar 34 N/ atau 34 Mpa. Diharapkan dari hasil analisis ini dapat sebagai tambahan pengetahuan mengenai analisa dan fungsi breakwater model A-Jack dan memperdalam pengetahuan dan penggunaan program SAP 2000 dalam menganalisis struktur beton.

(guided by Taufiqur Rachman and Achmad Yasir Baeda). The coastal area is a very intensive area used for human activities and activities. The existence of such activities can lead to increased demand for land and facilities and infrastructure which will lead to problems such as coastal erosion that can damage residential areas and urban infrastructure in the form of retreat coastline. One of the handling that can be done is to build a beach protective building such as breakwater. breakwater is an infrastructure built to break the wave by absorbing some waves. Breakwater also acts as a wave tranquilizer so the ship can dock at the port more easily and quickly. Therefore, to find out the response of A-jack structure as a decent breakwaters placed in Gusung Island, first take into account the wave load and wave energy that occurs along with the A- jack breakwater armor stability by using some empirical formula. The resulting wave energy is 375,71 N/m or 38,3119 kg/ / (0.0383 ton/meter), the wind load is 25,878 ton/m with the total vertical and horizontal force that occurs at building of ∑ = 384,172 t/m, ∑H = 89,5 ton/m then, the value of breakwater stability control against stability Shear = 1.53≥1,25 (Complies). After calculating the wave load, the next wave load is inputted to find out how the voltage that occurs in the structure, using SAP 2000 software displays a stiffness value at the foot of the structure of 9.000E-04 kgf/m and the stress occur in structures of 34 N/ or 34 MPa. It is expected that the results of this analysis can be additional knowledge of A-Jack model breakwater analysis and function and deepen the knowledge and use of SAP 2000 program in analysis concrete structures. Keywords: breakwater, A-jack, Energy Wave, Stress, Stability, SAP 2000. iv KATA PENGANTAR Assalamu’alaikum wr. wb.

  • GEOTEXTILE TUBE and GABION ARMOURED SEAWALL for COASTAL PROTECTION an ALTERNATIVE by S Sherlin Prem Nishold1, Ranganathan Sundaravadivelu 2*, Nilanjan Saha3
    PIANC-World Congress Panama City, Panama 2018 GEOTEXTILE TUBE AND GABION ARMOURED SEAWALL FOR COASTAL PROTECTION AN ALTERNATIVE by S Sherlin Prem Nishold1, Ranganathan Sundaravadivelu 2*, Nilanjan Saha3 ABSTRACT The present study deals with a site-specific innovative solution executed in the northeast coastline of Odisha in India. The retarded embankment which had been maintained yearly by traditional means of ‘bullah piling’ and sandbags, proved ineffective and got washed away for a stretch of 350 meters in 2011. About the site condition, it is required to design an efficient coastal protection system prevailing to a low soil bearing capacity and continuously exposed to tides and waves. The erosion of existing embankment at Pentha ( Odisha ) has necessitated the construction of a retarded embankment. Conventional hard engineered materials for coastal protection are more expensive since they are not readily available near to the site. Moreover, they have not been found suitable for prevailing in in-situ marine environment and soil condition. Geosynthetics are innovative solutions for coastal erosion and protection are cheap, quickly installable when compared to other materials and methods. Therefore, a geotextile tube seawall was designed and built for a length of 505 m as soft coastal protection structure. A scaled model (1:10) study of geotextile tube configurations with and without gabion box structure is examined for the better understanding of hydrodynamic characteristics for such configurations. The scaled model in the mentioned configuration was constructed using woven geotextile fabric as geo tubes. The gabion box was made up of eco-friendly polypropylene tar-coated rope and consists of small rubble stones which increase the porosity when compared to the conventional monolithic rubble mound.

  • The Impact of Submerged Breakwaters on Sediment Distribution Along Marsh Boundaries
    water Article The Impact of Submerged Breakwaters on Sediment Distribution along Marsh Boundaries Iacopo Vona *, Matthew W. Gray and William Nardin Horn Point Laboratory, University of Maryland Center for Environmental Science, Cambridge, MD 21613, USA; [email protected] (M.W.G.); [email protected] (W.N.) * Correspondence: [email protected] Received: 7 February 2020; Accepted: 31 March 2020; Published: 2 April 2020 Abstract: Human encroachment and development on coastlines have led to greater amounts of armoring of shorelines. Breakwaters are a common feature along coastlines, which are used to dampen wave energy and protect shorelines from flash floods or overwash events. Although common, their effects on sediment transport and marsh geomorphology are poorly understood. To address this gap, our study quantifies the effects of breakwaters on sediment transport and marsh evolution under different wave regimes using Delft3D-SWAN, a dynamic geomorphodynamic numerical model. Model configurations used the same numerical domain, but scenarios had different sediments, waves, tides, basin slopes and breakwater distances from the shoreline to explore how waves and tidal currents shape coastal margins. Model results suggested breakwaters were responsible for an average wave damping between 10–50%, proportional to the significant wave height across all modeled scenarios. Shear stress at the beginning of the marsh and the volume of sediment deposited at the end of the simulation (into the marsh behind the breakwater) increased on average between 20–40%, proportional to the slope and distance of the breakwater from the shoreline. Sediment trapping, defined as the ratio between the volume of sediment housed into the salt marsh behind and away from the breakwater, was found to be less than 1 from most model runs.

  • Shoreline Stabilisation
    Section 5 SHORELINE STABILISATION 5.1 Overview of Options Options for handling beach erosion along the western segment of Shelley Beach include: • Do Nothing – which implies letting nature take its course; • Beach Nourishment – place or pump sand on the beach to restore a beach; • Wave Dissipating Seawall – construct a wave dissipating seawall in front of or in lieu of the vertical wall so that wave energy is absorbed and complete protection is provided to the boatsheds and bathing boxes behind the wall for a 50 year planning period; • Groyne – construct a groyne, somewhere to the east of Campbells Road to prevent sand from the western part of Shelley Beach being lost to the eastern part of Shelley Beach; • Offshore Breakwater – construct a breakwater parallel to the shoreline and seaward of the existing jetties to dissipate wave energy before it reaches the beach; and • Combinations of the above. 5.2 Do Nothing There is no reason to believe that the erosion process that has occurred over at least the last 50 years, at the western end of Shelley Beach, will diminish. If the water depth over the nearshore bank has deepened, as it appears visually from aerial photographs, the wave heights and erosive forces may in fact increase. Therefore “Do Nothing” implies that erosion will continue, more structures will be threatened and ultimately damaged, and the timber vertical wall become undermined and fail, exposing the structures behind the wall to wave forces. The cliffs behind the wall will be subjected to wave forces and will be undermined if they are not founded on solid rock.

The Yunlin coast, a first-level protection area in mid-west Taiwan, was then used as an example to illustrate the proposed design criteria. The safety of the present coastal defenses and land use of the Yunlin coastal area was assessed, and coastal protection measures for hazard prevention were proposed based on the generated risk map. The results can be informative for future coastal management and the promotion of sustainable development of coastal zones. Keywords: coastal defense; risk maps; non-engineering measure; coastal vulnerability 1. Introduction Like most developing countries, Taiwan’s coast has been alternatively used for settlement, agriculture, trade, industry, and recreation without careful and thorough planning in the development stage since 70s.
