Iran faces special challenges in the conetxt of climate change due to its semi-arid to arid climate and its geographical characteristics. The country often suffers from severe drought, as rainfall is rare and irregular. These infrequent rainfalls are of short duration with very high intensities. Due to their sudden and unforeseen occurrence, the resulting flash floods pose a risk for living beings as well as material goods, which is often underestimated by the population. The catchment area of the Kan River in the province of Teheran must cope with these challenges. The area is characterised in the north by its steep mountain slopes and in the south by the capital city of Teheran with over 11 million inhabitants. This location mainly attracts local tourists who use the area for recreation.
