Using the Urumia lake water allocation problem as a case study, a conflict analysis method was applied to look for possibilities to resolve the problem of conflicting demands for water. First a thorough overview of the problem was made by describing the Urumia lake basin and the human activities therein as a Large Technical System. After the problem was defined as such, a graph model for conflict resolution was applied to look for possible resolutions. The possibilities to arrive at a fair water allocation were summarized in a basic road map.
