Abstract
<p><em>This study aims to identify riverbank erosion in some Tibo villages, Sindue Tambusabora District, Donggala Regency. This type of research is descriptive qualitative with a spatial approach. The data analysis technique used in this study includes a qualitative descriptive analysis in the form of a unit analysis of the area of landform from the fluvial process in Tibo Village, Sindue Tambusabora District, Donggala Regency. The data used in this study include primary data and secondary data. Primary data are the results of field ground checks and direct measurements, while secondary data are Landsat 8 OLI images and RBI maps of 1:50,000 scale 2015-65. This type of research is descriptive qualitative with a spatial approach. The data analysis technique used in this study includes a qualitative descriptive analysis in the form of a unit analysis of the landform area from which the fluvial process originated in the village of Tibo. Mild to moderate erosion and sedimentation rates. Erosion of cliffs is very high, especially at the bend of the river where erosion occurs due to high river discharge so that many charred rivers are found in Tibo village due to high erosion and sedimentation.</em><em></em></p>
Highlights
Riverbank erosion generally occurs at river bends (Aldhila Gusta H.Y dan Widiyanto, 2016)
The increase in riverbank erosion that occurred in the study area was caused by soil cover in the form of shrubs vegetation, farming patterns in the form of plantations, and high river discharge
This study aims to identify riverbank erosion in some Tibo villages, Sindue Tambusabora District, Donggala Regency
Summary
Tibo village has alluvial soil, mud, limestone, and coastal deposits. The ground check results in Tibo Village showed the same thing, namely the presence of sediment at the observation location. The high river discharge is the main factor in the cliff landslide in Tibo village If this is not done with mitigation efforts to overcome landslides when it rains for a long duration with high intensity, the road will be completely cut off which will have an impact on the activities of the village community. The occurrence of scoured river flow at the bend of the river caused cliff landslides on land owned by the community around Tibo village. The bend in the river has a great potential for erosion or cliff slides because the bend in the river has a very large impact force and erosion of the river flow This happened to the Code river in DIY, research conducted by (Aldhila Gusta H.Y dan Widiyanto, 2016) where the irregular river flows with many obstacles such as landslide prevention embankments can sharpen river bends and become the main cause of erosion along riverbanks. By knowing the type of landform from the fluvial process in the research area, spatial planning, especially in the agricultural sector, must always look at the risk of cliff landslides so that they can be minimized as small as possible
