Abstract: 3-D numerical models are being used more commonly to predict changes in coastal water quality associated with point discharges such as sewage outfalls. Because these “far field” models use grid sizes which are orders of ...

Abstract: In order to find out the ribs with the best anti-erosion efficiency, the erosion effects in three 90° duct bend gas-solid flows with different ribs are investigated and compared with that ...

Abstract: A geologic profile often is composed of multiple material zones due to complex geologic processes. Uncertainties associated with the geologic profile can be categorized into two groups: (1) intralayer variability, ...

Abstract: Karst caves are often encountered during karst tunnel excavation, and the shape of the karst cave has an impact on the stability of the tunnel surrounding rock. This paper focused on the effects of karst cave shape on the ...
