Abstract Deformation monitoring is a common practice in most of dams to ensure their structural health and safety status. Systematic frequently carried out by means geotechnical sensors geodetic techniques that, although very precise an accurate, can be time-consuming economically costly. Remote sensing are proved effective assessing deformation. Changes the structure, shell or associated infra...

A dam breaking is a major flood catastrophe. The shape, depth, and wave Doppler effect of initial water flow are all modified as result the interaction body with downstream structures after breach, forming diffraction reflection field. This study investigates problem single liquid, by creating two-dimensional simplified numerical model using VOF approach, analysing between barriers various form...

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...

Abstract It is commonly believed that the permanent deformation introduced by meizoseismal impacts of embankment dams, which impossible to be reinstated and will further endanger safety normal use thereof. In this study, a three-dimensional finite element model dam have been established with equivalent nodal force approach calculate dams under seismic protection. was indicated results accelerat...
