The dual use of drainage characteristics in groundwater potential modelling using remote sensing and GIS: an example from Dengi Area, Northcentral Nigeria

摘要: The need for refining of the skills employed in groundwater exploration and management is being emphasized as population surges importance water to meet these growing demands increases. Remote sensing geographical information systems have routinely been used targeting favourable zones thus necessitating attempt improve reliability this approach. While other factors like geology, elevation, slope, lineament density, contact proximity soil remain constant (within framework model), work incorporates both drainage density thematic layers into a single potential model by separating first-order streams from second- third-order streams, respectively. obtained via dual application yields more reliable results comparison field conditions than produced using either or alone. Consequently, integrated approach has proven extra usual encouraged.
