Where will All the Sediments Go? Impressions from Balin Dam Failure in Taiwan
The historic failure of Balin Dam happened in September 2007 and caused a big amount of sediment behind flushing downstream resulting from a tropical typhoon. The river bed upstream and downstream then started to evolve dramatically and showed significant differences soon after months. In this paper, we present the observations and impressions of this case. The situation here of a dam filled with sediment and at risk of failure, and the downstreaM release of decades of accumulated sediment is widespread in Taiwan and elsewhere. This unanticipated dam failure makes dam safety and sediment management even more crucial. There is an urgent need to develop and test strategies to deal with such sediment-impacted structures and establish more sustainable forms of water management in landscapes with high sediment yields and high energy rivers.
