About the Cover

In UIRB and globally, gully erosion is one of the most visible environmental and geomorphic hazards, which limits the maximum function of soils and landscape. Gully initiation and development increases runoff, soil loss, flooding and aids sedimentation. This research investigated and examined the gully morphological features and soil loss under various land covers of UIRB. It examined land cover change between 2008 and 2023; assessed the gullies under various land covers of the study area, analyzed the morphological features of the sampled gullies under land cover of the study area, and quantified the amount of soil loss resulting from gully erosion in various land covers. Landsat 8 and topographical maps was processed to identify the extent of the UIRB boundary. Eighteen gully sites were systematically selected considering the land cover of UIRB. Both primary and secondary data were was utilized in the research. Primary data are gully length, width, depth area, volume and slope gradient. The data was generated by field measurement and Digital Image Analysis (DIA) of the Landsat image of 2008 and 2023. The morphological properties obtained through measurement are the gully length, width and depth, while the gully areas, and soil loss were derived. The research identified five land covers in the study area between 2008 and 2023. All the identified land covers showed a wellobserved change (gain/loss) within the time of study. The built-up area with 6.99% gain e showed the greatest gain in LC, while farmland with 12.79% loss indicated the highest loss in LC. Assessment done on the gullies in various LCs showed that none of the gullies in UIRB originated from water bodies. Built up areas and farmland has the greatest number of gullies found in them, containing 77.8% (39.8% each) of all the gullies in the study area.
