Flood studies and effects of climate change : two examples

Usually, various kinds of floods are distinguished based on the origin or on the main processes. Basically, the cause of the flood can be overflow over the banks of the main channel, direct runoff or failure of a levee or other structure. Flash floods are typical of steep beds and / or high intensity rainfalls. In mountain areas, they can be associated to debris flows or highly concentrated bed load. In urban areas, they often follow the reduction of infiltration and of drainage network. All these kinds of floods could have their parameters modified because of climate change but effects will be obviously varied in terms of consequences.
