(IADA BLS), Under the average of 14 scenarios, for example, the high WSI in Sabak<br />

Bernam, Selangor would affect the water supply sustainability at IADA BLS, while<br />

the extremely high WSI in Johor Bahru is associated with high water demand<br />

due to highly populated and rapid development that would undoubtedly bring<br />

challenge in supplying sufficient treated water to consumers.<br />

5 CONCLUSION<br />

Climate change studies by various agencies all around the world are in fact,<br />

applying the big data technology analytics in assessing and projecting climate<br />

variability in all its complexity and dynamic processes. Concurrently, the field of<br />

hydro-climate informatics, sciences and computational sustainability are rapidly<br />

growing and continuously changing. The uncertainties of future climate, its<br />

impacts to water resources and environment can be quickly processed, analysed<br />

and projected as key information in addressing and managing future waterrelated<br />

risks. Through data linkages, data mining and analysis, and predictive<br />

analytics, decision making processes are improved and thus can increase<br />
