  • The Basics of Slope Stability Analysis for Geosynthetics

    Slope stability analysis is vital to preventing slope failures in a variety of engineering applications including landfill design, roads, dams and embankments, to name a few. Proper analysis anticipates both natural and manmade slopes and failure of foundations and retaining walls. This blog covers the necessity of slope stability analysis, how to conduct the analysis and the role of ...

  • New Cascadia: Game changers & Joshua trees

    Close your eyes and try to imagine the most inhospitable landscape you can. It’s arid, with little or no vegetation. The trees and shrubs that do grow are small and often prickly. It’s boiling hot during the day and can drop well below freezing at night, yet there is no shelter from the elements. And imagine you are sitting in a new Cascadia. On the rare occasion of rainfall, flash ...

  • Helping farmers and regulators manage and assure the cumulative flood safety of agricultural dams: a cost-effective regionalised review/design tool from Australia

    In Australia and other countries, small private dams in agricultural catchments pose both disastrous individual and cumulative dam failure flood threats to downstream communities; threats that can be exacerbated by increased rainfall intensities caused by climate change. This paper addresses the need for a low cost, scientifically acceptable mechanism and policy guidance to help dam owners and ...

  • The development of a real-time flooding operation model in the Tseng-Wen Reservoir

    Typhoon events occur frequently in Taiwan resulting in flood-related disasters. A well-operated reservoir can reduce the severity of a disaster. This study incorporates a genetic algorithm, a river hydraulic model, an artificial neural network and a simulation model of Tseng-Wen Reservoir to propose a real-time flooding operation model. The model includes two parts: an optimal flooding operation ...

  • Safety and hazards in CCS projects

    Carbon capture and storage is now on the technological tipping point – it has reached critical mass with one large-scale, fully integrated power project now almost operational at the SaskPower Boundary Dam project in Canada, using enhanced oil recovery. In the UK, following the announcements of progress at two projects, Peterhead and White Rose, the government’s competition process ...

  • A novel multi-objective electromagnetism-like mechanism algorithm with applications in reservoir flood control operation

    Reservoir flood control operation (RFCO) is a complex problem that involves various constraints and purposes, which include the safety of the dam, watershed flood control and navigation. These objectives often conflict with each other. Thus, traditional methods have difficulty in solving the multi-objective problem efficiently. In this paper, a multi-objective self-adaptive electromagnetism-like ...

  • Time lapse resistivity/IP survey case study

    Changes in underground electric resistivity is typically resulted by the variations in groundwater conduction and soil water content. Monitoring this variation will help operator gain a better understanding of the underground water distribution over time.  This may facilitates operators monitor abnormal underground or structural behaviour. Time lapse resistivity survey is ...

  • Dam safety inspections

    This dam safety inspection was carried out to monitor the safety of a stone masonry overflow dam (12m high and 161m long). The geological makeup of the region comprises Ordovician period limestone and loose Quaternary sediments. One set of data was collected by placing 64 ...

  • Assessing seepage flow conditions through a dam quickly and accurately without drilling or drawing down the reservoir

    This paper examines the application of a proven geophysical technology that is highly effective in assessing seepage flow conditions through, beneath and around earthen embankments. The technology works rapidly with minimal disruptions to dam operations—it requires no drilling or draining of the reservoir. It has become a competitive solution to many of the complex challenges faced with dam ...

  • Dam security and underwater attacks

    According to DHS (2007) dams provide a wide range of important economic, environmental, and social benefits. These benefits include: recreation, flood control, water storage, irrigation, mine tailings, electric generation, debris control, and navigation (see Figure 1; DHS 2007). Their destruction through intentional attack can largely impact the economy and public safety.  Dam security is ...
