Abstract:

Flood is defined as an overflow of water that submerges land which is usually dry. Today, many parts of the world experience unexpected flood events due to different reasons. Among the most important factors, land use and climate change affect flooding in many ways. The present study aims to investigate the impacts of land use and climate change on flood events, as well as, its outcomes on urban communities(basin Ferdows in IRAN). Definition and evaluation of different adaptation options is a necessary step, because information in this area will help urban communities reduce their current and future vulnerability to floods. The extreme rainfall is supposed to increase during twenty-first century while the rate of changes is unclear due to climatic models. During 2013-2050, the peak discharge will increase between 12+8 and 13+7 for three models and the return period will exceed 50 years. There is more uncertainty for the next 50 years with an increase between 10+7 and 16+8 for two models. The results show that continuous changes happen with a degree of uncertainty while recent unplanned and rapid urbanization has a possibility to induce serious urban flooding in the near future which will lead to a greater hazard for societies.
