Are contours and spot heights obtained from topo sheets of more than 50 years be useful today, in designing an effective water supply distribution network in urban centers in tropical counties like Nigeria, considering the degradational and aggradational activities that have taken place over the years?
Completion of the maps will provide a significant GIS scientific database to support interpretative hydrological hypotheses for conceptual ground water models and regional surface-water and ground water flow systems by enhancing the stratigraphic and structural information where such detailed information is ...
