In August 2008, a massive flood on the Koshi River in Nepal breached its east embankment, damaging a vast area of farmlands and standing crops in the Sunsari district in the eastern region. Less than a month later, incessant heavy rains caused severe landslides and flooding, ravaging the Kailali and Kanchanpur districts in the far western region.
The rapid economic growth of the People’s Republic of China (PRC) has depended in part on reservoirs, which have facilitated flood control, irrigation, hydropower generation, and water supply. These reservoirs are grouped by the country into three safety classes. Class III, comprising 37,032 reservoirs or 43% of the total as of end−2006, are the least safe.
