Scope In response to recent disasters by huge natural forces such as Tohoku Earthquake Tsunami, a huge amount of rainfall by Typhoon Talas and a continental-scale flood in Thailand, people met an doubtfulness for engineering countermeasures and/or mitigation effects of terrestrial ecosystem. Ongoing climate change is also amplifying the doubtfulness in the prediction of hydrological cycle. In JpGU meetings over the past few years, the subjects including included to evaluate effects of human ecosystem disturbances on hydrology and to build strategies of long-term hydrological observations necessary for the evaluation have been discussed. Now, we need an additional subject, that is, to study hydrological responses to unexpected huge natural forces. We will discuss on: 1) to predict a huge unobserved flood based on analyses of observed floods with smaller-scales. 2) to evaluate ecosystem roles for huge floods. 3) to estimate effects of large-scale land-use changes on huge floods. 4) to specify a causal connection between flood/draught occurrences and climate/ecosystem changes. 5) to develop methodologies on the investigation and analysis for a prediction of hydrological responses to unexpected natural forces. New tasks in the hydrological science are now needed to explicitly reflect social demands for these subjects. Preliminary studies are also welcome for our challenging subject.
Notes Conclude the speech within 20 miniutes for a presentation with the allocation time of 30 minutes to secure enough discussion time. Conclude it within 10 minutes for that of 20 minutes.
