Information Generation and Sharing

There is a need for robust notification and information sharing procedures in environments where basin boundaries differ from the administrative boundaries. The issue is particularly challenging, if ownership of communities and their participation is to be ensured.

Flood management strategies should be based on scientific data gathered by a variety of agencies often under different administrative control. These strategies must be reviewed in light of the experiences of new flood events. Mechanisms must therefore be in place to feed basic hydrologic data, planning parameters, social, environmental and economic considerations and assessments of actual performance back into the strategic planning process. In addition, various types of information that are generated in the monitoring process are required for:

It is essential that the collection of meteorological and hydrological data is consistent at the national as well as regional level. Within a country, problems may arise where separate hydrological monitoring bodies are responsible for different regions or constituent states. The national government will normally be responsible for ensuring that data collection methodologies are consistent across all regions, through legislative instruments if considered necessary. Moreover, an obligation to update and share the data among the respective agencies in real-time should be provided for in relevant by-laws.

An additional obligation with respect to data collection relates to post-flood assessment of the event. If lessons are to be learned from flood events, it is crucial that the planning agencies understand the precise circumstances that contributed to the flood event and the impacts. To increase the comparability of flood damage data, standards for damage assessment should be considered and the competent authority charged to undertake this type of assessment.
