| Abstrak/Abstract |
Watershed is an area that can accommodate, store and drain rainwater towards
the outlet which flows to the lake or the sea naturally. Coastal conditions in a
watershed are heavily influenced by some factors of watershed such as the landform,
morphology, morphometry and land use. Factors of the watershed can reveal the
character and nature of the watershed as well as the potential for floods in coastal
areas. Remote sensing as a science and technology can help in understanding the
factors of the watershed that affect to inundation flood and potential of inundation
flood that could occur in coastal areas. Kayan watershed in North Kalimantan
province, floods often occurs both in upstream and downstream. Coastal areas are
likely to become the center of public economic activities, making it susceptible to
flooding. The purpose of this research was to determine the factors of the watershed
that affect the inundation flood and zoning for the potential of inundation flood in
coastal areas with remote sensing data. Methods for obtaining the factors watershed
is the interpretation of remote sensing data and geographic information system
analysis. The results of this study are the description of the various factors of the
watershed that affect to inundation flood and level of inundation flood potential in
coastal areas based on the whole watershed. Inundation flood zone in coastal areas
are flood-prone areas with 81,738.54 Hectares and very prone to flooding with
87,375.43 Hectares. |
