عنوان انگلیسی Flood Peak Discharge Trend over Iran
چکیده انگلیسی مقاله Aims:  Studying flood peak discharge trend is crucial to disaster risk reduction in developing countries like Iran. This study aims to analyze the instantaneous peak discharge trend in 301 hydrometric stations using Mann Kendal (MK (and Sen’s Slope estimator tests over Iran.
Materials: All existing hydrometric stations data in the entire country of Iran were downloaded from Iran Water Resources Management Company. The hydrometric stations with at least 20 years of data were selected, and the stations that were then affected by the dams were removed. Trend analyses of instantaneous peak discharge were conducted using MK and Sen’s slope estimator tests.
 Results: The results showed that out of 301 hydrometric stations, 259 stations have no trend, and only three stations have a decreasing trend and 39 stations have an increasing trend, which is in the southwestern part of the Iran country, where the increase in agriculture, human activity, and climate change is more evident in these areas. In the watershed of the eastern border, there is only one station that has a decreasing trend, and in the central plateau, four stations have a decreasing trend, and the rest of the stations have no trend.
Conclusion: Due to the importance of the role of peak discharge in flood damage, this research can help managers and decision makers in the integrated watershed management. For example, in flood control projects, as well as designing the dimensions of structures such as retard dams, levees, the height of flood control walls and bridges.
