This research focused on evaluating and understanding how exactly the landscape of Ndele area in Emohua L.G.A of Rivers state changed. The primary data for the study was gotten from the classification and extraction of DEM resolution 30m×30m LANDSAT TM– imagery downloaded for 1986 and 2016; from Earth Explorer United State Geological Survey; while the secondary data were gotten and retrieved from simulation output results of LAPSUS. LAPSUS, a free and an open source, GIS-based LEM model employed to simulate short-term topographic change for both steady and dynamic regimes transversely within a range of 104 year spatial scale in Ndele. The simulation analysis was carried out with the aid of an unfiltered digital elevation model (DEM) and five scenarios’ (water driven erosion and deposition, weathering, tillage, tectonics, and collapse) interacted under no supervision, producing model output results. From the results, it was evident that elevation is higher in the South-east and lower in the North-west. The North-west area is situated roughly between 165 and 1m, while the south west area is situated around 385m to 274m.
