River scientists strive to understand how streamflow regimes vary across space and time because it is fundamental predicting the impacts of climate change human activities on riverine ecosystems. Here we tested whether flow periodicity differs between rivers that are regulated or unregulated by large dams, dominant periodicities over in response dam regulation. These questions were addressed ca...

Reservoir sedimentation is a worldwide problem affecting sustainable storage use as well as sediment transport downstream of dams. Various techniques are applied for sediment mitigation, among which, venting of turbidity currents. This paper reviews, discusses and evaluates venting of turbidity currents based on an experimental approach. Data acquisition during the tests is accomplished using f...

This paper looks at issues associated with estimating risk of seismically initiated failure (uncontrolled release of the reservoir) of dams that are co-located with respect to each other and the location of future earthquakes. These may be dams on the same river or dams regionally co-located on different rivers. Failure of one or more dams could lead to serial dam failures on a single river; or...

Overtopping dam break is a frequent accident in tailings reservoirs. However, little attention has been paid to the study of overtopping hydraulic erosion damage characteristics after adding reinforcement. Nowadays, there were few people have researched prediction failure process reinforced dam. It important significance establish model for which aims at problem tailings. For anti-erosion and a...

NEDO has developed MEPAS, a software for exploration of geothermal reservoir. MEPAS has bcen developed as a tool for geologists to analyze earthquakes and find fractures by comparing earthquakes with other exploration data. MEPAS consists of a seismic data processing part and a geological analysis part. The geological analysis part features 3D display, time and space distribution display, fract...

Presently, the fluvial fluxes of Dissolved silicate (DSi) by many famous rivers in the world have been reported significantly decreased in the past several decades. DSi retention by river damming hence becomes a great concern. In this study, the impact on DSi retention and transport by cascade reservoirs in the Karst area were investigated. Based on the monitoring data for four seasons, budget ...
