Sustainable integrated land-use plan and flood risk management: A review

摘要

Floods have always been the natural disaster causing the greatest loss of human life and eco-nomic damage across the globe, at local and global levels. Several studies suggest that for many river basins, flood risk will further increase during the 21st century as a result of not only climate change but also economic development and land-use changes. Land-use changes can influence several surface and near-surface hydrological processes. These processes may in-clude evapotranspiration, interception, infiltration, overland flow, surface and subsurface runoff and surface retention. It is also important to analyse the spatio-temporal dynamics of flood expo-sure due to urban development along the rivers as well as other areas upstream and down-stream. In this paper, we review the impact of land-use change process on flood damage poten-tial and discuss measures to manage flood risk. The main contribution of this paper is to high-light a general evolution of flood prevention policies, from a techno-centred approach towards a preventive integrated sustainable flood and land-use management approach.
