Abstract

A Case for GIS in Water Resources in Ghana
Track: Water Resources
Authors: Francis Ocansey

The common occurrence of high iron and manganese content in groundwater sources for extraction for water supply delivery is a major limitation factor in ensuring access to clean portable water in Ghana. To demonstrate the potential of GIS in monitoring and managing water supply systems to water resources personnel, a GIS implementation on small towns' water supply project was carried out. Firstly as a database management tool with advance query abilities and for water quality modelling and mapping. Through the challenges of what can GIS do different, sources of data and standardisation to the revealing sources of water quality problems? It was significant to visualise in map form the locations of the 59 borehole points and their salient characteristic attributes data overlaid on the geologic basemap. In GIS it was clearly evident about the descriptive and prescriptive nature of the tool and therefore necessary as a decision making support system.
