Sri Lanka Water Resources Information System
The objectives of this information system are as follows:
- Provide a clear understanding of the status and trends of the country’s water resources.
- Provide a web-based interactive information and mapping portal for exploring data, information and maps related to water resources.
- Produce a water resources assessment for Sri Lanka at various scales (river basin, administrative boundary, etc.)

Water Data Portal
WaterData is an integrated portal providing a one stop access to all data stored in IWMI’s archive. It also provides access to data in IDIS and IWMIDSP. While providing access to large amount of water and agriculture related data, the system also supports data management in IWMI’s research projects. Access to data is provided in compliance with copyrights, intellectual property rights and data agreements. As a User your access to data stored in WaterData is therefore limited to what you are authorized to use.

IWMI’s World Water and Climate Atlas
The IWMI World Water and Climate Atlas gives irrigation and agricultural planners rapid access to accurate data on climate and moisture availability for agriculture. The Atlas includes monthly and annual summaries for precipitation, temperature, humidity, hours of sunshine, evaporation estimates, wind speed, total number of days with and without rainfall, days without frost and Penman-Montieth reference evapotranspiration rates. The core of the Atlas is data assembled from weather stations around the world for the period 1961-1990. Data can be extracted in summary, manipulated using the Atlas software, or exported in a standardized format for use in other applications. Users can also include their own local data for a more detailed picture of a particular area.

IWMI’s Drought Monitoring System
A prototype regional drought monitoring system (DMS) for South-West Asia was developed in 2004 with funding from the US State Department Regional Environment Office for South Asia. It was meant to serve as an illustration of capabilities provided by remote sensing data for drought monitoring and as an example that may be replicated (and developed further) in other regions. The system uses an on-line remote sensing database to monitor drought development through continuous assessment of the condition of ground vegetation. It operates at the fine level of spatial resolution (0.5 km X 0.5 km) and in near-real time, whereby new data can be added every 8 or 16 days.

Eco-Hydrological Databases on this site contain specific information pertaining to various aspects of functioning, requirements and management of freshwater ecosystems. The information is extracted from formally published papers and reports, unpublished documents, Internet sites and experts opinions.
