Based on the Saint-venant equations describing the channel flow movement, the nonlinear algebraic equations derived by the use of Preissmann weighted implicit four-point scheme are solved with the Netwon-Raphson method. A combined Gauss main-element elimination method with compress-storage technique is proposed. The relaxation iterative method for solving branch river networks is extended, which can turn the problem of any complex river networks into the problem of a series of single rivers.

Based on the environmental performance information in oil company's separate environmental report and the 30 environmental performance indicators of Global Reporting Initiative, this article found that, most important environmental performance indicators are not fully disclosed and those disclosed are qualitative instead of quantitative. Company even discloses fewer indicators year after year. What's more, positive activities and indicators are more elaborated. Information is scattered. All of these lead to the incomparability and difficulty of environmental performance evaluation.
