Mapping geomorphological environments of bendo watershed ijen mountain, banyuwangi east of java

Abstract

Geomorphology is a comprehensive landscape study that reviews a space from the aspects of morphology, chronology, arrangements and processes. Accompanied by observation and field validation, the rapid development of remote sensing technology greatly helped the geomorphological mapping process. This research is aimed at geomorphological mapping of the Bendo Watershed area which can then be used as a basis for various spatial studies. The hybrid approach and on screen image interpretation (OSII) method on DEM data, optical satellites, and lithology units was carried out to obtain morphological, morphochronological and morphoarrangement information, while morphoprocess information was obtained through field observations. Sixteen units of landforms have been successfully mapped consisting of the origin of volcanic and fluvial processes with upstream morphological characteristics in the form of slopes of the Ijen Complex and downstream in the form of fluvial plains. Overall surface material is a product of volcanoes in the upstream area with a process of erosion and dominant landslides. Mapped landform units can be a unit of analysis and basic information for regional planning studies, land evaluation, and disaster.
