Exploring the Geomorphological Nature and its Consequences in Agaie & Lapai L Gas of Niger State and Environment Using GIS & LandSat-8 Imagery

Abstract

The activities of geomorphology has persisted over many years in the study area un-noticed, un-checked or controlled and un-abaited. That is why, this article is poised to evaluate the morphological consequences on the study area topography, particularly settlements and farm-land areas along the fringes of the river (coast) and suggest way-out. In order to assess the magnitude of morphological changes over-time, the of Geographic Information System (GIS), Remote Sensing (RS) techniques (that is, using LandSat Imagery-8) and Shuttle Radar Thematic Mapper (SRTM) were deployed and survey method (via a structured questionnaire) to extrapolate the socio-economic consequences on the inhabitants of the study area. The GIS, RS and SRTM revealed the morphological changes and its evolution such as the drainage pattern, topography (that is, relief), flooding and flood plains. It is expected that, policy makers, water resources engineers and environmental managers would find the out-come of this investigation use for planning and making informed decision to avert future environmental hazards of different types.
