Semester Offering: January

Floods and droughts are one of the most destructive natural phenomena in Asia and around the world. They can cause serious damage to life, properties, public utilities and infrastructures. They hamper social and economic growth of developing countries. Knowledge on hydrology of floods and droughts; understanding on their causes, frequencies and magnitudes are required to achieve effective management and mitigation measures of floods and droughts.
