Assessing the impact on groundwater safety of inter-basin water transfer using a coupled modeling approach

Haifeng JIA,Shidong LIANG,Yansong ZHANG

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 1,   Pages 84-95 doi: 10.1007/s11783-014-0741-2

Abstract: Surface water and groundwater always behave in a coupled manner and are major components of hydrologic cycle. However, surface water simulation models and groundwater simulation models are run separately most of the time. Few models focus on the impact of hydraulic changes in the surface water flows on the groundwater, or specifically, the impact of a water transfer project to fill a seasonally dry channel. In this study, a linked surface water and groundwater simulation model was developed to assess the impact of a trans-basin water diversion project on the groundwater. A typical plain area east of Beijing was selected as a case study, representing Beijing’s main source of groundwater used for drinking water. A surface water quality model of the Chaobai River was developed based on the Water Quality Analysis Simulation Program (WASP), and a groundwater model was developed based on the Modular Finite-Difference Groundwater Flow Model (MODFLOW) and the Modular 3-D transport model (MT3D). The results of the surface water simulation were used as input for the groundwater simulation. Water levels and four contaminants (NH -N, COD , F, As) were simulated. With the same initial and boundary conditions, scenario analyses were performed to quantify the impact of different quantities of diversion water on the groundwater environment. The results showed the water quality of the groundwater sources was not significantly affected.

Failure Analysis, Safety Assessment, and Nondestructive Testing for Mechanical and Electrical Equipment

Zhong Qunpeng,Wu Huaisheng,Zhang Zheng,Tian Yongjiang

Strategic Study of CAE 1999, Volume 1, Issue 1,   Pages 43-48

Abstract:

This paper, from the viewpoint of epistemology, clarifies the position, role, and attributes of failure analysis and prevention in the development of science and technology. The discipline of failure analysis and prevention is multidisciplinary and inter-synthetical. It dependents on the development of both aplied sciences and pure sciences and has great positive effects on them.So, it is one of the most active factors in the conclusion of “Science and technology are the first productivity.” This paper also describes the dialectic relationship between failure analysis and failure prevention methodologically. While failure analysis is a process of converse thinking expost factor, which explores scientifically causes from results, the failure prevention is a process of prior thinking, which predicts results from causes.It is necessary to utilize the both thinking methods simultaneously and convert the afterwards analysis to the prior one for the development of science and technology. Finally, this paper summarizes the main contents, techniques, methodology, and future trends of failure analysis and prevention and the relationship between nondestructive testing and failure analysis and prevention.
