Numerical Simulation of The Time Effect to Rocks With The Fluid-Structure Coupling Condition

Moli Zhao, Wen Wang
The solid and fluid phases are not miscible phases while solid deformation and fluid transport are generally coupled processes. On long time scales, fluids allow stress-driven creep in the middle rock mass with the constant pressure. This paper aims to demonstrate time effect to rocks with the fluid-structure...

Feasibility Analysis of Seawater Desalination in Urban Municipal Water Supply in Coastal Cities

Boyu Liu, Chengpu Liu, Rongwang Guo, Jinfeng Jiao
China cities are in the state of shortage of water in recent years. Although large scale projects have solved some of the city's municipal water supply problems the linear water supply policy still can’t cover all the small and medium-sized city. In recent years, seawater desalination technology has...

Land transformations in Hanyang city of Wuhan in Central China 2001-2011

Yan Li
Using the case of Hanyang, this paper provides new evidence of land transformation in China. Together with massive non-urban to urban land transformations, there is an increasing proportion of land being converted from urban to non-urban uses. The results of exploratory spatial data analysis demonstrate...
