| dc.description | Indonesia merupakan negara yang sangat rawan terkena bencana alam seperti
gempa bumi, dan tsunami. Selain itu Indonesia juga rawan terhadap bencana
hidrometeorologi seperti banjir dan tanah longor. Salah satu dari banyaknya
penyebab tanah longsor yaitu karena tigginya intensitas curah hujan pada suatu
kawasan tertentu. Pada penelitian ini akan dikaji distribusi faktor aman dan
distribusi tekanan air pori pada lereng saat berada dalam kondisi hujan. Nilai-nilai
faktor aman dan kenaikan tekanan air-pori tersebut diperoleh dari hasil pemodelan
numerik menggunakan software TRIGRS(The Transient Rainfall Infiltration and
Grid-Based Regional Slope-Stability Model) versi 2.0. Hasil dari pemodelan
tersebut selanjutnya diolah dalam software berbasis Geographic Information
System sehingga distribusi nilai-nilai faktor aman dan kenaikan tekanan air-pori
dapat divisualisasikan dalam bentuk peta spasial 2-Dimensi. | en_US |
| dc.description.abstract | Indonesia is a country which prone to natural disasters such as
earthquakes, and tsunamis. In addition, Indonesia is also vulnerable to
hydrometeorological disasters such as floods and landslide. One of the many
causes of landslides is due to the high intensity of rainfall in a particular area. In
this research we will examine the distribution of factor of safety (FS) and
distribution of pore-water pressure on the slope while in rain condition. The
values of the Factor of Safety (FS) and the increase of pore-water pressure were
obtained from numerical modeling using the TRIGRS (The Transient Rainfall
Infiltration and Grid-Based Regional Slope-Stability Model) version 2.0 software.
The results of the modeling processed in a Geographic Information System-based
software so that the distribution of Factor of Safety (FS) values and pore-water
pressures can be visualized in the form of a 2-dimensional spatial map. | en_US |
