Certainly some effect of climate change couples with other anthropocentric activities disturbing the normal cycle. Further unplanned and over crowded settlements in natural watersheds and drainage also causing the problem of flood.
In Italy since the last 15-20 years hydrogeological disaster have been increasing, 'cause of the more concentrated rainfall even in urbanized area (with huge catastrophic effects on man and environment). This trend could be transposed in all the Mediterranean areas and in Middle East countries.
we are also in Iraq, where there are extremes of rain that exceed their rates every year. During the current season (2018/2019), the rains are exceptional and very heavy. There have been major floods and serious damage caused by flash floods.
