DISTRIBUSI SPASIAL GENANGAN AIR LAUT BERDASARKAN ANALISIS DATA SATELIT ALTIMETRI ENVISAT DI WILAYAH PESISIR BARAT KABUPATEN BULELENG, BALI
Abstract
This research was conducted in the western coastal region of Buleleng which includestwo districts, namely: Seririt District and Gerokgak District. The research aims were (1) to
analyze the trend of the dynamics of sea level in the period of 2002 to 2010, and (2) to predict
the spatial distribution of flood of sea water. The data used are Envisat satellite altimetry data
from the results of post-processing data, which were then analyzed the trend of mean sea level
and forecast of sea level rise for year 2020 using linear regression analysis. To determine the
spatial distribution of area flood of sea water, then the data of level rise forecast were analyzed
with Geographic Information System (GIS). The results of this research define that the functional
relationship of the trend of mean sea level rise in the area of research is y = 0.051 x + 1.612. The
prediction of mean sea level rise that is obtained every year 5.1 cm and for 2020, the sea level
rise is predicted to reach 2,224 cm. The width of coastal area that is potentially flooded of sea
water reaches 812.954 m2 (0.227%). Spatially, the widest food area is Pejarakan village and the
narrowest is Celukan Bawang village. The percentages of the villages that are flooded to area
villages show a relatively homogeneousdistribution.
