Abstract :
Floods are disasters that often occur in several
parts of Indonesia. Almost every area that has a low
altitude must have experienced flooding, one of which is
Samarinda City. Flooding in Samarinda City is common
and frequent. The use of SRTM images as material for
analyzing natural resources and natural disasters, where
data collection does not require direct contact with the
objects studied is very effective and efficient in terms of
time, cost and human labor.
The purpose of this study was to create a surface
flow map in Samarinda City with Shuttle Radar
Topography Mission (SRTM) satellite image. Knowing
terrain of catchment area in Samarinda City.
The research method used is analysis of Surface
Flow Forecast using Shuttle Radar Topography Mission
(SRTM) Satellite image and carrying out the process of
making surface flow forecasts for Samarinda City using
Arc GIS 10.3 software. Data processing is carried out
using Arc ToolBox as a tool in Arc GIS 10.3 software by
creating water flow and catchment area with
downloaded SRTM satellite image.
The results of study can provide information about
the waterway and the area of the accompanying
catchment area in Samarinda City as a consideration of
Samarinda City government's policy in flood
management. The results showed that most of
Samarinda area is in the Karang Mumus sub-watershed
so that catchment area shown through data processing
on application used gives very broad results, which is as
wide as 46,699.44 Ha. Areas outside of Karang Mumus
sub-watershed area gave the result that, the area of
water catchment in Samarinda Utara district is 6,258.73
Ha, Samarinda Ulu 24.55 Ha, Sambutan 4,046.87 Ha,
Sungai Kunjang 438.76 Ha, Loa Janan Hilir 61.35 Ha,
Palaran 10,536.40 Ha.
Six sub-districts, namely Sungai Pinang,
Samarinda Seberang, Samarinda Kota and Samarinda
Ilir are sub-districts located entirely in the Karang
Mumus sub-watershed area.
Keywords :
Shuttle Radar Topography Mission (SRTM), water flow estimation, remote sensing.
