Environmental Impact Evaluation

In this paper, the predictive data of hydrodynamics and sediment are input into a systematic comprehensive evaluation model for guiding the marine reclamation in Tianjin. The predictive data are obtained by the numerical simulated results of hydrodynamics, water exchange and sediment. The systematic comprehensive evaluation model is proposed by a nonlinear cloud theory method, which has characteristics of high precision and concise. So the presented model is used to evaluate the feasibility of marine reclamation and resource utilization, named that Ergang Island. This research shows that the predictive comprehensive environmental impact evaluation method is an efficient tool for guiding the marine reclamation and improving the precision of environmental impact evaluation conclusion.

Pair Analysis

Despite the rapid development of risk analysis in dam engineering, there is a relative absence of research on the environmental impact of dam break. As a systematic theory, set pair analysis has a good effect in dealing with uncertainties, although the result is relatively rough and easy to distort. A connection degree of five grades and a generalized set of potential are introduced to improve traditional set pair analysis. Combined with the index system, the evaluation model of the environmental impact of dam break is established, which is based on generalized set pair analysis. Taking Sheheji Reservoir dam as an example, a comparison of evaluation results of fuzzy mathematics theory and generalized set pair analysis is made, which verifies the scientificity and practicability of the method proposed in this paper. The results show that the evaluation grade of the environmental impact of dam break at Sheheji Reservoir is serious, and appropriate management measures should be taken to reduce the risk.
