Flood influence using GIS and remote sensing based morphometric parameters: A case study in Niger delta region

This study delineates morphometric parameters for determining flood influence on river catchments in the Niger Delta Region using geospatial techniques. Data from United States Geological Survey; Shuttle radar topographic mission was processed ArcGIS 10.6 software. The results of hydrological data analysis, compound factors, and weighted overlay approach demonstrate that early peak flows River cause flooding along riverbanks, as evidenced by stream frequency findings. Ikoli River's consistently provide with its discharge a considerable time. Orashi, Bomadi, Forcados, Nun, basins all have low relief ratio hence little impact floods. However, higher contribute more water shorter amount time produce floods lower locations. Because high runoff short concentration time, Orashi catchment is most flood-prone, followed Forcardos catchments, which indicate "high," Ikoli, Bomadi "medium." It therefore advised Niger, Forcados be prioritized order to reduce research region.
