Accelerated Erosion: Generation of Digital Elevation Models (DEMS) for Gullies in Irele Local Government Area of Ondo-State, Nigeria
This study attempts to derive Digital Elevation Models (DEMs) for gullies at Ode-Irele, Lipanu, Akotogbo and Ajagba town in Irele Local Government Area (LGA) of Ondo-State, Nigeria. Gully morphometric attributes such as surface slope, catchments area, average depth and width as well as cross-sectional area and volume of material/ soil excavated were determined.
