We　will　introduce　an　integrated　model　of　Online　Decision　Making　Meetings　(ODMM)　for　sustainable　management　of　water　resources,　which　combines　online　meetings　with　an　agent-based　simulation　function.　This　model　is　able　to　supply　the　decision　makers　with　visualized　simulation　results　of　different　policy　scenarios　and　then　support　them　to　have　online　discussions,　communication　and　make　final　decisions.　The　model　consists　of　a　remote　server,　a　simulation　model　for　background　processing　and　clients.　We　assume　that　several　departments　related　to　water　resource　management　will　join　this　meeting　and　make　proposals　based　on　their　data　and　policy.　These　departments　are　clients　in　our　model　and　they　are　granted　with　special　authority　according　to　their　departments.　During　an　online　meeting,　the　clients　can　choose　global　parameters　for　a　simulation　model　that　relates　to　their　department　based　on　their　roles.　Afterwards,　simulations　for　different　scenarios　can　be　conducted　by　the　model　and　the　simulation　results　will　be　displayed　for　and　visualized　by　the　clients　through　the　server　on　time.　Thus,　the　government　planners　can　easily　view　the　simulation　results　regarding　different　policy　scenarios　using　this　tool,　thereby　making　informed　decisions　and　policy　implementations.　©　SPSD　Press　from　2010,　SPSD　Press,　Kanazawa.
