KARAKTERISTIK GEOMORFOLOGI DAN HUBUNGANNYA DENGAN SEBARAN LITOLOGI DAERAH WAY LAGA DAN SEKITARNYA, KOTA BANDAR LAMPUNG, PROVINSI LAMPUNG

Abstract

The study of the shape of the earth's surface appearance as evidence of geological processes that occur in an area, or geomorphology, often expresses the characteristics and distribution of the lithology of the constituent rocks. The aims and objectives of this study were to determine the geomorphologic characteristics and their relationship with the distribution of constituent lithologies in the Way Laga area and its surroundings, Bandar Lampung City, Lampung Province. The research was conducted using DEM SRTM data and compilation with geological maps from previous studies which were then processed in Global Mapper and ArcGis software. Geomorphological characteristics were analyzed by approaching geomorphological aspects such as morphography (landform and drainage pattern), morphometry (slope), and morphogenetics (endogenous and exogenous). The landscape/geomorphology formed in the study area is influenced by the characteristics of its constituent lithology. The study area has geomorphological characteristics that can be grouped into 3 units, namely the Moderately Steep - Very Steep Structural Hills Geomorphology Unit with volcanic rock lithology, namely tuff and some clays, the Sloping - Moderately Steep Hills Geomorphology Unit with schismic lithology, the Structural Plain Geomorphology Unit with tuff lithology.
