Analysing neo-tectonic effects on gully development within orlu and environs south-eastern nigeria from landsat imagery and azimuthal sounding data
Geophysical study was carried out in some gully erosion sites within Orlu and environs with the objectives of identifying tectonic and neo-tectonic features, delineate their trends and evaluate their effect in gully development and propagation in the study area. Detailed geological field mapping was carried out to characterize the gullies and to estimate the strikes and directional trends of the gullies. Similarly, GIS interpreted Landsat-ETM imageries were also used to determine the lineaments and their trends in the study area.
