The next big idea in conservation: Improving dams for nature and people

(April 6, 2010) Dams block the fluid highways used by migrating fish, and rearrange natural water-flow patterns that have choreographed aquatic life cycles for millennia. Analogs to human health are instructive: While water pollution is as harmful as excessive cholesterol in a bloodstream, the construction of dams has in many rivers been as fatal as cardiac arrest.

Prediction of reservoir-induced earthquake based on fuzzy theory

(April 4, 2010) Abstract—With more and more reservoirs have been and are being built all over the world, reservoir-induced earthquake has received a great deal of attention from geoscientists mainly because of its potential to damage constructions and to cause human losses. Based on the previous researches on the environmental conditions of reservoir-induced earthquake, a criteria hierarchy model has been constructed.
