SIMULASI NUMERIK DARI PROFIL ALIRAN DEBRIS

NUMERICAL SIMULATION FROM DEBRIS FLOW PROFILE

Author :
ROHIM, FATHUR ( 1207201711 )




ABSTRAK

Lahar merupakan aliran lumpur yang mengandung bongkah-bongkah berasal dari kegiatan gunung api atau aliran massa yang bercampur air dan bahan lepas dengan berbagai ukuran. Aliran debris juga sering terjadi akibat erosi pada dasar lereng yang miring. Penelitian ini bertujuan untuk menemukan profil aliran debris yang berasal dari erosi pada dasar kanal berdasarkan kemiringan lerang, bilangan Froude, dan bentuk gundukan di dasar lereng tersebut yang dipengaruhi oleh grafitasi bumi dengan Teknik Integral Batas (Boundary Integral Teknique) yang dilanjutkan dengan integrasi numerik Quadratur Gauss suku-dua. Hasil penelitian ini menunjukkan bahwa kemiringan lereng sangat berpengaruh terhadap profil aliran debris sedangkan bilangan Froude hanya sedikit pengaruhnya.


ABSTRACT

Lava mudlow is a set of mud which contains chunks comes from volcano activies of mass flow mix with water and other materials in many size. This is one of the example of debris flow. Debris flow is often happined couse of erotion on base canal. This research was cobducted to fet debris flow appearance comes from erotion in base canal on declivity, froude number and a from of pile canal influence by eart gravity with boundary integral technique numerical integration of gauss quadratur. This result of this observation show that the sloping corner is very influence to profile of debris flow, so the influence of froude number is very litle.
