Abstract:
This research is important to do to improve flood disaster management in the Walanae
Watershed, with the aim of researching and analyzing the most effective appropriate land use to
reduce the risk of flooding and damage. This research was carried out in the Walanae Watershed,
Dua Boccoe District, Bone Regency, South Sulawesi Province. Appropriate land use that is most
effective in reducing the risk of flooding and damage is analyzed descriptively qualitatively with
the Overlay approach. Assuming that the process produces data from the findings in the form of
field observations. The impact of appropriate land use that is most effective in reducing the risk
of flooding and damage is measured using the basic physical condition analysis method, this
superimpose analysis is used to determine flood-prone areas based on several aspects and a
qualitative descriptive analysis will clearly describe the impacts that have been caused by floods.
The results showed that there are 8 sub-districts/villages that have the potential for flooding,
including Unyi Village, Uloe Village, Pekkasalo Village, Kampoti Village, Tocina Village,
Tawaroe Village, Solo Village, and Matajang Village. With an area of 131 km2
, and an existing
inundation height of ±100–200 cm and an inundation period of 10 hours, Dua Boccoe Subdistrict
has the potential to be affected by flooding. Floods in Dua Boccoe Subdistrict are caused by
internal factors: Topography, Drainage Infrastructure, Building Density, and Land Use and
others as well as external factors: Topography, and Shipment Floods
