Gerusan setempat pada kaki bendung mengakibatkan terganggunya stabilitas pondasi sehingga dapat menimbulkan patahan (cracking).\nDalam studi ini telah dilakukan analisa data penelitian mengenai hubungan antara kecepatan aliran (v) dan bilangan froude (Fr) terhadap kerusakan (gerusan setempat) yang terjadi pada endsill bendung. Besarnya kedalaman gerusan dipengaruhi oleh tinggi terjunan, debit per satuan lebar (q), kecepatan aliran air (V) dan kedalaman air (y). Kecepatan aliran mempengaruhi besar kecilnya nilai bilangan froude (Fr). Bilangan froude (Fr) digunakan untuk menentukan jenis aliran. Jika Fr < 1 merupakan jenis aliran sub-kritis (laminar), Fr = 1 jenis aliran kritis (transisi) dan Fr > 1 merupakan jenis aliran super kritis (turbulen).\nHasilnya memperlihatkan bahwa hubungan antara kecepatan aliran (V) dan bilangan froude (Fr) terhadap kedalaman gerusan (ds) adalah berbanding lurus dengan persamaan linear y = 71.77x \u2013 1.179 (kecepatan aliran terhadap kedalaman gerusan) dan y =268.2x \u2013 4.666 (bilangan froude terhadap kedalaman gerusan) . Hal ini dapat dikatakan bahwa semakin besar kecepatan aliran (V) dan bilangan froude (Fr) maka gerusan yang terjadi akan semakin dalam.\nKata kunci : kecepatan aliran, bilangan Froude, gerusan lokal, bendung","abstract_alt":null,"creators":[{"role":"author","family_name":"Anggrek","given_name":"Valentino Alveraldi","orcid":null,"national_id":"2112181126"},{"role":"advisor","family_name":"Siregar","given_name":"Chandra Afriade","orcid":null,"national_id":"0418047301"}],"year":2023,"date_issued":"2023-03-10","publication":null,"volume":null,"issue":null,"pages":null,"publisher":null,"isbn":null,"issn":null,"doi":null,"official_url":null,"institution":"UNIVERSITAS SANGGA BUANA YPKP","id_number":null,"thesis_level":"bachelor","publication_status":"published","refereed":null,"keywords":["kecepatan aliran","bilangan Froude","gerusan lokal","bendung"],"language":"id","subjects":[],"divisions":[{"code":"22201","name":"S1 Teknik Sipil","pddikti_code":"22201"}],"citation":"Anggrek, Valentino Alveraldi (2023) KAJIAN PENGARUH BILANGAN FROUDE (Fr)\nDAN KECEPATAN ALIRAN (V)\nTERHADAP KERUSAKAN ENDSILL KAKI BENDUNG\nDENGAN UJI MODEL HIDROLIK LABORATORIUM.
