  • Why Geocells Outperform Geogrids for Road Construction

    Geocells (cellular confinement) offer a more effective and practical 3D design solution to load support challenges than multilayered 2D geogrid efforts. Geocells transfer applied loads instantaneously, delivering practical soil stabilization in a product that is fast and easy to install. How do geogrids work? Geogrids rely on rutting, displacement and lateral movement of the road ...

  • Application of a three-dimensional hyperbolic location system to the false killer whale (Pseudorca crassidens) depredation issue

    Depredation by false killer whale (Pseudorca crassidens) is a serious problem for pelagic longline fishing in the Coral Sea. These interactions have raised substantial ecological, economic and social concerns. McPherson et al. proposed post-processing of passive acoustic recordings to analyse general odontocete acoustic behaviour and assess the effectiveness of systems being developed to reduce ...

  • Case Study - Steep slope erosion control (Bijao Beach Resort,Santa Clara, Panama)

    Background: The Bijao Beach Resort community resides in the balmy region of Panama near Santa Clara’s beaches. It was constructed as a luxury resort to compete with nearby Playa Blanca and Decameron. An artificial mountain was created to enhance the geography of the resort. Native soil of the area was compacted and stabilized with biaxial geogrid, but rain has wreaked havoc upon ...


  • Drought class transition analysis through different models: a case study in North China

    The standardized precipitation index (SPI) and standardized runoff index (SRI) are computed for several gauge stations in Panjiakou Reservoir catchment of Luanhe Basin, a drought prone region of North China. Based on the SPI and SRI time series, two different models, a weighted Markov chain model and a Volterra adaptive filter model for chaotic time series, were established to predict drought ...

  • Case study - Airport platform

    Mexico City's international airport was built over a lake; the soil is expansive clay with water content approaching 200%. Settlement is a severe problem and several airport runways necessitated a 4m asphalt layer thickness. A recently constructed airport platform using a conventional pavement was expected to settle 3 cm at the 3 vertical loading points of the airplane over two years. In fact it ...

  • Composite protection for slopes - Dallas Eastside Water Treatment Plant, Texas - Case study

    Geocells, geotextiles and geomembranes resolve the chronic erosion problems of a municipal levee. In 1996, consulting engineers under con-tract to the City of Dallas contacted Soil Stabilization Products Company Inc. (SSPCo) to discuss solutions for chronic problems caused by more than a dozen sliding failures per year on the outer slopes of a water treatment facility's lagoon. The facility, ...

  • Geoweb Erosion & Hard-Armor Protection Mccook Quarry Flood Reservoir - Case Study

    Project overview Permanent erosion protection was necessary for the McCook Quarry flood reservoir for the City of Chicago. The reservoir averages 300 ft deep and is approximately 1.75 miles in diameter. The 105 ft long slopes above the quarry face required a system that would be low maintenance and stable at 2H:1V. A major site specific challenge was installing an erosion control product on ...

  • Waste Rock Back Analysis

    On October 4, 2004, during field measurements collected in trench LFG-008, a crack developed in the middle of the trench. This occurred during the destruction of the Goat Hill North (GHN) rock pile at the Questa site. The crack varied in width up to a maximum of 100 mm and extended in an arc pattern around the pushed out section of the slope. The slope had been pushed in a convex arc out from the ...
