The evolutions of practices of seismic slope stability analysis of earth embankment/dam are discussed in this paper. The basic concepts of various methods, salient features, advantages and limitations of each of them are elucidate. Methods for both stability analysis and deformation calculation are presented. Methods for calculation of deformation of post liquefaction stage are also briefed.

Dam-break is a serious disaster resulting in severe damage to downstream communities. Therefore, analyzing the affected range and evolution process of dam-break floods advance valuable. However, difficulties challenges lie complexity breaking earth-rock dams, uncertainty floods, geographical variability. Given this, objective this study analyze characteristics flood evolution. The chooses Cheng...

Wood is an important component of flash floods and debris flows in forested mountainous areas. To better understand the characteristics large wood (LW) movement its destructive effects on check dams, bridges, buildings, we conducted field investigations theoretical calculations flood process Keze gully Jiuzhaigou National Park (China). Based calculation method, magnitude amplification ratio pea...

Habitat fragmentation is the primary cause of the loss of biodiversity and ecosystem services, but its underlying processes and mechanisms remain poorly understood. Studies of islands and insular terrestrial habitats are essential for improving our understanding of habitat fragmentation. We argue that the Three-Gorges Dam, the largest that humans have ever created, presents a unique grand-scale...

The active Séchilienne landslide (Isère, France) has been continuously monitored by tacheometry, radar and extensometry devices for 25 years. Indeed, if the 3 mil. m 3 of rocks in the active zone named ―Ruines‖ fell down, the debris would dam the Romanche valley. The breaking of the dam by overtopping and rapid erosion would bring a catastrophic flood and other dramatic consequences throughout ...

The potential of Local Sensitivity Analysis (LSA) for analysis of uncertainty with respect to two major risks in river hydrodynamics flash flood and dam failure is assessed. LSA, implemented as an equation-based method, is compared to a Global Uncertainty Analysis (GUA) consisting in running Monte Carlo simulations with a hydrodynamic model. For a given statistical distribution of the model inp...

The restorative potential of dam removal on ecosystem function depends on the reversibility of dam effects and its operations. While dam removal is an established engineering practice, the need for an understanding of the ecological response remains. We used paleoflood hydrology, hydrologic modeling, and aerial photo interpretation to investigate the long-term ecologic responses to dam failure ...
