Rubber dams inflate water supply

Article Abstract:

The Orange County Water District (OCWD)'s ground-water recharge program includes the constructionof three rubber dams in the Santa Monica River in California. The dams will substitute for temporary diversion dikes and are intended to help divert water for Southern California's use. Excessive flow rates have rendered OCWD's traditional method of diverting Santa Monica's river flows as useless and this results in the discharge of too much water into the ocaean. The rubber dams will ensure better water diversion by lessening the rebuilding of the scoured levees and diversion dikes. These will also improve water quality by allowing silt and debris to flow out.

Seismic assessment of tailings dams

Article Abstract:

A methodology for assessing the seismic stability of tailings dams and possible upgrading frameworks is presented. The main seismic design factors involved in this analysis are the site-specific earthquake-induced motions and the seismic behaviour under seismic loading. Themethods of analysis in the assessment of the significance of the design seismicloading on the tailing structure are enumerated and discussed. The impact of the failure on people and the environment, cost and feasibility of upgrading works and the risk or probability of failure are the requirements in seismic upgrading.

When the levee inflates

Article Abstract:

The use of inflatable dams and tubes to protect property from flood damage is being investigated by researchers at Virginia Tech, Blacksburg, VA. Such dams, usually filled with air, water or a combination of both, are easy to install, withstand extremes of temperature and require little maintenance. Most of the world's inflatable dams are made by two Japanese companies, Tokyo-based Bridgestone and Sumitomo Electric Industries of Osaka.
