Intersection of lineaments for groundwater prospect analysis using satellite remotely sensed and aeromagnetic dataset around Ibodi, Southwestern Nigeria

Abstract

This research investigates groundwater potential of Ibodi and its environs using satellite imagery, respectively. The map showed that the concentrations of lineament intersection nodes dominate the eastern and north-eastern parts of the study area while other areas are characterized by scanty or no lineament intersections nodes. The lineament analysis has been effectively done in a geographic information system (GIS) environment. Results from the vertical electrical sounding (VES) data reveals that the areas where the lineament intersected has tendency of very high groundwater prospect which reflects that the area will be good for groundwater development. The study thus displays that the remote sensing and aeromagnetic technique is capable of extracting lineament trends in an inaccessible tropical forest and has led to the delineation of areas where groundwater occurrences are most promising for sustainable supply.

Investigation of the influence of lineaments, lineament intersections and geology on groundwater yield in the basement complex terrain of Ondo State, Southwestern Nigeria

“…The analysis in Tables 4 and 5 corroborated the works of Lattman and Parizek (1964), Sander 1997, Mabee et al (2002, Bayowa et al 2014, Dasho et al (2017, that wells located on or near lineaments or at the intersection of lineaments gave yields greater than wells placed between lineaments and outside lineaments. Siddigui and Parizek (1971), Mabee (1999), Bayowa et al (2014), Adiat et al (2012), Yene et al (2015 and Ilugbo et al (2017) also found that wells sited on lineament had productivity greater than randomly located wells.…”

Effect of Lineament and Drainage Orientation on Groundwater Potential of Moro Area Central Kwara State Nigeria

“…Rose diagram was also generated for the lineaments in the study area using the Georient software program. Automatic extraction of lineament is better than the manual lineament because of its ability to uniformly extract the different images; complex but subjective method, absolutely depends on the intricacy of the research area and slight effect of human subjection [2]. Identification and mapping of targets of lineaments required digital processing of the satellite imageries [10].…”

“…Groundwater occurs in the cracks and holes that exist in the rock units. Knowing that groundwater potential of a basement complex terrain is determined by a complex interrelationship between the geology, post-emplacement, tectonic history, weathering processes and depth of occurrence, composition of the weathered layer, aquifer types, groundwater flow pattern, climate, recharge and discharge processes [1], lineament and drainage orientation may have a significant effect on groundwater potential of an area [2]. Effectual method for mapping of fracture zones is based on lineament indices generated from air-photos and from satellite imagery [3].…”

“…The challenge is traced down to several factors and it is expedient to evaluate the relationship between the lineament, topography and surface water flow direction; as they will in no doubt contribute to aquifer productivity in a typical basement complex terrain. Several [5,2] have define lineaments as extended and comprehensive mappable linear or curvilinear features of a surface whose parts are in a straight or nearly straight relationships that may be the manifestations of folds, fractures or faults in the subsurface. An aquifer can only be productive if the pore spaces and/or fractures are associated giving rise to an increased porosity and permeability of the aquifer.…”

Groundwater Sustainability and the Divergence of Rock Types in a Typical Crystalline Basement Complex Region, Southwestern Nigeria

“…However, due to rapid population growth and human development, the land use for building and industrial development is on the increase. This has becomes a major challenge within the basement complex region especially where the areas characterized by thick overburden has been subjected to other applications rather than groundwater development, thereby exposing the populate to the development, exploration and exploitation of groundwater by a way of harnessing water from structural features associated with crack, fault, fractures or highly weathered materials with little or no reasonable overburden thickness (Olorunfemi et al, 1991;Ilugbo and Adebiyi, 2017;Babatunde et al, 2018). Delineation of zones of major anomaly/weak zones characterizing of high water bearing zones for sustainable water development in a typical complex crystalline basement rock terrain such as that of Akure and its environment southwestern Nigeria, 2 TURKGEO requires a strategic approach that involve more than one geophysical techniques for random sampling (Isogun and Adepelumi, 2014;Ozegin et al, 2019).…”
