Sistem Informasi Geografis Penentuan Wilayah Rawan Banjir di Kabupaten Buleleng

Abstract

This study aims to (1) create a design and
implementation of geographic information systems (GIS) to
determine flood-prone areas in Buleleng regency (2) to analyze
factors such as rainfall causes flooding, land use and topography
using GIS to determine areas prone flooding in Buleleng regency.
SIG design is the determination of flood-prone areas described
using UML (Unified Modeling laguage). The process of
determining the flood-prone area analysis is done by providing the
weighting of each factor causing floods in Buleleng, ie rainfall,
land use, and topography. Weights given by the size of the effect is
given to flooding. The greater influence of these factors on the
occurrence of floods, then the greater weight given.
The final result of the analysis process with the weighting
factor is the flood zone classification of flood vulnerability that is
divided into four levels, namely grim prone, prone, prone enough,
and safe. Of the four levels of the results are displayed in the form
of thematic maps flood vulnerability areas in Buleleng. From the
results of testing both structural and functional systems generated
that the system is capable of running in accordance with the
expected results that produce flood vulnerability information in the
form of thematic maps flood vulnerability.
