  4. Abstract:
  5. Flood as a natural disaster causes heavy human and economic losses and social unrests in most areas of the world. As flood control cost and flood damage compensation is a heavy burden over countries' budget, traditional flood design methods are being replaced by more reliable risk-based methods employing comprehensive risk analysis. In this respect, flood damage estimation is an important step in flood control systems design and analysis. In large river basins with complex reservoir systems and various land uses, flood damage estimation is complex, data-intensive, time demanding, and uncertain task requiring an intensive hydrologic and hydraulic analysis. In this study a simple approach is proposed for this purpose, using GIS data and Google Earth images. In this approach, various analyses are performed to determine the effect of peak flood flow and high-flow duration on flood damage in different parts of the basin with different topography. This approach has been applied to the Karkheh River Basin in West of Iran. Karkheh river rises in the Zagros Mountains, and passes north of Shush (ancient Susa), eventually falling into the Tigris just below its confluence with the Euphrates very near to the Iran-Iraq border. The results have been helpful in the analysis of flood control systems
