The Red Rock Hydroelectric Project converted the existing Dam near Pella, Iowa, from a non-powered dam into multi-purpose dam. flood control was constructed by U.S. Army Corps of Engineers (USACE) in 1960s on Des Moines River Iowa. hydroelectric project developed Western Minnesota Municipal Power Agency and generates up to 55 MW with an average annual energy output 178 gigawatt-hours. new intak...

jazmoryan wetland is one of the most sensitive ecosystems in the south east of the country which is declining due to dam construction in upstream as well as deficiency of environmental water supply. the wetland seem to dry out due to its geographical location and construction of bampour diversion dam and jiroft reservoir dam on major rivers flowing to this wetland. one of the solutions proposed...

In the course of carrying out these activities, the environment is degraded and thereby damaging the ecosystem and the landscape, and offsetting the already fragile ecological balance [1]. Obviously, LUCC studies provide a great and significance information to strengthen the protection of land resources, determent unreasonable exploitati...

Dam construction poses significant ecological impact, both during the initial phase and long after dam is completed. The Diamer Basha Dam, situated on River Indus in Gilgit-Baltistan district of Pakistan, receiving attention due to consequences proposed ongoing construction. a 272-m-tall reservoir with 9867.912 Mm3 (million cubic meter) capacity will be world's highest roller compact concrete d...

A collaborative virtual geographic environment (CVGE) is a 3-D, distributed, and graphical world representing and simulating geographic phenomena and processes to enable geographically distributed users to explore geoproblems and theories and generate hypotheses, and to support geomodel building and validation and collaborative ecological planning. This chapter reports an approach to establishi...

In this paper, case study on outlet cracking is first conducted for the Goupitan and Xiaowan arch dams. A nonlinear FEM method is then implemented to study effects of the outlets on integral stability of the Xiluodu arch dam under two loading conditions, i.e., normal loading and overloading conditions. On the basis of the case study and the numerical modelling, the outlet cracking mechanism, ri...
