Displacement Based

Convolution PML is known to have excellent wave absorbing capability, and has been used combined with FDM and FEM. Most of them are splitting type formulation for explicit FEM or FDM. Here implicit non-splitting type convolution PML procedures consistent with mixed formulation FEM as well as displacement based FEM are developed. The resulting coefficient matrices for convolution PML are symmetric if corresponding coefficient matrices of FEM are symmetric. The developed method is applied to dam-reservoir-foundation systems including reservoir cavitation, and the validity of the method is demonstrated.

AbstractRecognition of the deteriorating conditions of rivers worldwide has called for increased efforts to improve the ecological quality of impacted river systems. This is particularly important in areas that have suffered from a significant impact of human pressure on the ecological status of water. Field studies were conducted in the Ruda River in an area that had undergone anthropogenic disturbances. The objectives of our survey were to test the biological metrics based on benthic macroinvertebrates at four study sites. Spring and autumn surveys of benthic invertebrates indicated that based on the BMWP and BMWP(PL) indices, water quality was higher in comparison with the value of Multimetric index at all of the sites that were studied. Our results revealed that the water quality was higher at the study sites that are located above the dam reservoir based on both the chemical and biological parameters. This study also indicated that both spring and autumn constitute appropriate periods for carrying out monitoring studies. The values of multimeric index indicated the same water quality (except for site 1) in both sampling periods. Anthropogenic transformations of a riverbed influence the flora and fauna and affect the ecological status of rivers.
