Decision support system for flood control andudecosystem upgrading in the Red River basin

摘要

A decision support system (DSS) for the selection of a suitableudcombination of flood control and ecosystem upgrading measures wasuddeveloped. This was achieved by carefully selecting the most appropriateudmodel environment for the DSS. The hydrological, hydraulic and socioeconomicudmodels within the DSS are constructed in a consistent way, takingudinto account the project objectives, characteristics of the measures, spatial andudtemporal scales and future scenarios. The developed DSS was applied to theudRed River basin in Vietnam and China to evaluate a number of measures. Thisudreveals that some measures may decrease the flood damage, but may alsoudresult in a decrease in total income and hence total revenues. The describedudresults are an illustration of how measures can be selected in the DSS. Moreuddata collection and model calibration and validation are needed beforeudemploying the DSS for real flood management.
