Determination of discharge coefficient of inbuilt spillway in rock- fill dams

According to the former researcher’s presented relations for flow through rock-fill porous media, the effects of physical characteristics was not studied separately. Hence, due to the application of these relations, physical characteristics of porous materials effect must be investigated separately. In various constructed physical models of porous media, the effect of several variables such as ...

in High-Dimensional Numerical Modeling

In the present paper, we discuss the novel concept of super-compressed tensor-structured data formats in high dimensional applications. We describe the multi-folding or quantics based tensor approximation method of O(d logN)-complexity (logarithmic scaling in the volume size), applied to the discrete functions over the product index set {1, ..., N}⊗d, or briefly N -d tensors of size N, and to t...

Two Alternative System Reliability Approaches to the Serviceability Condition Assessment of Spillway Gate Systems on Dams

Modeling a washout of dams

Worldwide 83% of large dams are embankment structures (ICOLD, 1984), and the proportion is even greater for small dams. Embankment overtopping and breach is an important issue, and the Discusser congratulates the Author for his worthwhile contribution which complements the comprehensive study of Coleman et al. (2002). This discussion is focused on the breach development stage. It is shown that ...
