<p>Teluk Prigi merupakan perairan di pesisir Samudera Hindia yang dikelilingi oleh bentang alam tebing yang tinggi sehingga wilayah pesisir yang memiliki kondisi dinamis dapat mengakibatkan terjadinya perubahan garis pantai apabila tidak dikelola dengan baik. Maka dari itu pada penelitian ini bertujuan untuk mengetahui faktor oseanografi yang menyebabkan terjadinya perubahan garis pantai. Metode yang digunakan terdiri dari pemisahan arus, peramalan gelombang, gelombang pecah, energi gelombang dan refraksi gelombang dengan menggunakan metode menurut <em>Coastal Engineering Research Center </em>(CERC). Selain itu ekstraksi garis pantai dengan metode <em>NDWI (Normal Differential Water Index)</em>, dan analisis jenis sedimen menggunakan modul yang dikeluarkan oleh Pusjatan Balitbang PU. Faktor oseanografi yang dominan menjadi penyebab perubahan garis pantai adalah gelombang bangkitan angin yang pola gelombangnya mengalami perubahan arah yang cenderung tegak lurus pantai, selain itu arus pasang surut menjadi faktor pendukung dengan kecepatan 0,0037 m/s bergerak menuju Utara. Sehingga, kondisi garis pantai pada tahun 2003 dan 2014, 2014 dan 2018 luasan sedimentasi terbesar mencapai 28.949 m<sup>2</sup> dan 52.020 m<sup>2</sup> yang berada di Desa Prigi. Sedangkan Sedangkan lokasi abrasi pada tahun 2003 dan 2014, 2014 dan 2018 luasnya mencapai 4.204 m<sup>2</sup> dan 3.326 m<sup>2</sup>.</p>

The U.S

In the 1970s, the U.S. Congress authorized and funded a five-year demonstration program on low-cost methods for shore protection called the “U.S. Army Engineers Shoreline Erosion Control Demonstration (Section 54) Program.” The Section 54 also known as the “Low-Cost Shore Protection” demonstration program is revisited. Demonstration and monitoring sites including the materials, devices, vegetative plantings, approaches tested, and program findings are discussed. Simply put, a major finding of the Section 54 program was that the concept of “low-cost shore protection” was a bit naïve. However, the program did lead to a wealth of public information documents and practical coastal engineering lessons that are still resonating as home owners, communities, and engineers consider alternative approaches for managing coastal erosion. The program structure and findings are applicable 40 years later as consideration is given toward the use of Natural and Nature-based Features (NNBF) for addressing coastal erosion. Evolution in thought relative to coastal erosion and shoreline enhancement activities since the 1970s has built upon many of the lessons and concepts of the Section 54 program and other real-world coastal erosion management success-failure experiences. This growth has led to a modern appreciation that those features that emulate NNBF are promising and responsible alternative coastal erosion management strategies if proper engineering standard elements of design are included in the project.
