Earth–rock dams are typical soil–rock mixtures with high heterogeneity. Mastering the effect of dam heterogeneity on seismic wavefields is premise accurately detecting hidden risks in dams. In this paper, based mixture characteristics actual dams, a model that can reflect established through local segmentation and reassignment random disturbances. The influence area size described. wavefield nu...
Earthquakes are natural phenomena that cause terrible disasters for human society. Many of the caused by earthquakes around world serve as warnings to us about fragility life and immaturity science - especially construction science. For earth dams, which made up mostly compacted earth, most common type in world, an earthquake can have enormous consequences if it causes a dam failure. Thus, prop...
One of the most vital problems in the storage and utilization of surface waters for drinking, flood control, hydropower, and agricultural purposes is that of sedimentation in reservoirs and subsequent decline of dam lifetime. The useful lifetime of a dam is defined as the time necessary for approximately 80% of the volume of its initial capacity to be filled by sediments washed in by water. It ...
Estimation of sediment transport load due to erosion in river basins is one of the issues which is indispensable for many projects related to water resources, soil and damps construction. With regards to the phenomenon of erosion and transmission Sedimentation in rivers has always led to deformation in the seaboard and sedimentation, so the management and planning in bank of rivers is important...
