Water-related Disasters and Hydrological changes

The study of extreme phenomena at the hydrological level should consider human beings as part of the hydrological system, either as agents of change or as beneficiaries of ecological services. Social and environmental changes related to the management of water resources have a direct impact on the quality of life societies. In particular, with regard to economic damage and loss caused by water-related disasters, such as floods, droughts, landslides and subsidence, that has increased dramatically globally, largely because of population growth in vulnerable areas. Other forces involved are the change in land use, urbanization, new migratory phenomena, energy requirements and food production, all aspects of population change and economic development.

The major challenge for the hydrological community is to identify appropriate and timely adaptation measures in a changing environment. In addition, there is a need to improve the capacity to establish predictions favoring basins without measuring systems. Finally, it is necessary to be more dynamic and effective in disseminating results to ensure the knowledge base of policymakers and decision makers.
