Introduction
Drought monitoring program was initiated since early 2001.
Objectives:
-To disseminate info, on-line on the Water Resources Status
-To provide early warning on Potential Drought
-Technical Advisory on Drought Status
Methodology:
Closed relationship between water resources status and current rainfall
amount received. Therefore, in this program rainfall data of 41
selected stations are used in the analysis to reflect the water resources status
of Peninsular Malaysia. In this case the percentage of deviation from the long term mean
(LTM) value of 3 monthly moving rainfall totals is used as indicator of the water
catchments condition. A negative deviation from the LTM value indicates that the
particular region is experiencing a dryer than normal condition and vice versa.
In general if a certain catchment is receiving rainfall (3 monthly
rainfall total) less than 60% of the LTM for a consecutive period of 3 months and
more. Then, it may be expected that the amount of run-off or water resources of that
catchment to be adversely affected. It is, therefore hoped that this monthly monitoring
program will serve to provide early warning on the impending water shortages of a
particular region.
Thus, follow up analysis and measures can be activated by the relevant agencies to
mitigate the water stress problem
