GIS based water quality monitoring system in pacific coastal area: A case study for Fiji

摘要

Nowadays Geographic Information System (GIS) and Remote Sensing (RS) techniques are used in different area of research for monitoring, collecting and analysis data from various geographical locations. Due to the vast increase in global industrial output, rural to urban drift and the over-utilization of land and sea resources, the quality of water available to people has deteriorated greatly. The high use of fertilizers in farms and also other chemicals in sectors such as mining and construction have contributed immensely to the overall reduction of water quality globally. Water is an essential need for human survival and therefore there must be mechanisms put in place to vigorously test the quality of water that made available for drinking in town and city articulated supplies and as well as the rivers, creeks and shoreline that surround our towns and cities. The availability of good quality water is paramount in preventing outbreaks of water-borne diseases as well as improving the quality of life. Fiji Islands are located in the vast Pacific Ocean which require a data collecting network for the water quality monitoring where GIS system can be applicable. This Paper presents a case study of water quality monitoring system with (key Performance Indicators) KPIs for Suva city, using GIS and remote sensing technology.
