| dc.description.abstract | The change in land use and land cover in a particular area will always change the features of drainage systems such that they will impact surface overflow and affect the infiltration capacity of a land surface, which is one of the factors that contributes to flooding. The key objective of this study is to assess the effect of land use land cover change on flood occurrence using remote sensing data, and GIS-based mapping approaches. The purposes of this investigation were to;
• Investigate the Land use and Land cover changes in Mbale between 1992 and 2022.
• To identify and analyze the flood prone areas within Mbale district.
Landsat imagery of 1992, 2002, 2012, and 2022, DEM, Rainfall and Soil data were utilized for this study and Analytical Hierarchy Process (AHP) which is a multi-criteria decision analysis method was used to determine weights for each contributing factor to do a weighted overlay. The results show a significant increase in the Built Up areas and show a significant decrease in the forest cover of the area. Mbale has a high and very high likelihood of around 54.8% of the total area, and a low and very low likelihood of around 45.2% of the total area as of 2022. The region’s high and very high likelihood mostly falls in the low lying areas of Mbale district. Therefore, identification of these flood hazard zones is essential for early preparation in the region. The study offers basic information about flood hazard areas for central governments, local governments, NGOs, and communities to intervene in preparedness, responses, and flood mitigation and recovery processes, respectively. | en_US |
