Urban water management
Urban floods are events that cause most casualties and economic losses, because these occurrences affect great number of people, properties and infrastructure. Flood events can be determined by two main factors: the first one is location of the towns or cities near the river beds. The second factor is related to strong, concentrated and sudden rainfalls. In this case urban floods occur due to the lack or clogging of the sewers or due to the total lack of filtration. Due to the above facts, urban areas can face high risk of flooding in very short period of time.
