2. Introduction
• Sri Lanka owns different types of water
resources .Click>>
• Historically Sri Lanka had great hydraulic
civilization
• Presently water resources management is
essential to Sri Lanka
3. – 103 river basins (4560 km)
(Ministry of Forestry and Environment, 1999)
– More than 20 major
wetlands
– Minor and major irrigation
systems
– Groundwater resources
– Coastal and marine
resources. Click>>
• Sri Lanka
– 2400 m3 of available per
capita water resources
– 2000 mm of average
annual RF (Ariyabandu, 2008) click>>
5. Historically
• Great ancient hydraulic civilization in Sri
Lanka
– Water used for
• Irrigation
• Domestic requirements
• Urban recreations
• Small scale industries
– However
• Water was managed properly
– Sustainably
– Participatory
6.
7. But…..
• Temporal and spatial water scarcity
• Pollution
• Agrarian demand to sectoral demand. Click>>
– Industrial demand
– Environmental demand
– Electricity demand
– Recreational demand
Sustainable water resources management is
essential… Click>>
11. Statistical Downscaling…
• Downscaling for
– Rainfall OND
• Second inter-monsoon period
• 16% of quantity
• Important to land preparations for “Maha” season
(64% of paddy cultivation)
– Temperature OND
• Average 270C
24. Conclusions
• For OND season SSE & SCM can used to
predict rainfall at 44% success rate
• For OND season SCM can used to predict
temperature at 44% success rate
Unable to predict rainfall for the next season, because the stations what
we selected were failed at screening
25. Using Dynamic Downscaling
• Software : RegCM 4
• Predicted Region : Sri Lanka
• Latitude : 5 N – 10 N
• Longitude : 75 E – 85 E
• Duration : 1998 June
38. Conclusion
• RegCM 4.0 is very usable to predict
South-west monsoon to Sri lanka
• Because past experiences showed the
same results observed from the RegCM
4.0 for the same monsoon season
39. Further Work
• Simulate long term predictions via
RegCM3
• Upload more applicable Sri Lankan station
precipitation data for CLIK on-line
application
