  • 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 ...

  • Virginia dOT slope protection, Collinsville, Virginia

    Prior to 1988, the sandy clay embankments along Route 220 near Collinsville, Virginia were subject to severe erosion and loss of vegetative cover, particularly after heavy rainfalls. The problems were most severe on embankments with steep slopes. These problems persisted despite numerous attempts to stabilize the soil and control surface erosion. In April of 1988, the Virginia Department of ...

  • Ohio slope erosion, Cleveland, Ohio

    Every day, over 100,000 vehicles drive on I-480, a six lane Interstate highway around Cleveland, Ohio. To improve the appearance and correct some heavily eroded areas, the Ohio Department of Transportation decided to landscape 3.5 miles (5.6 km) of both cut and fill slopes on the north side of I-480. Their plans called for regrading, draining, and planting trees, shrubs and various plants. ...

  • Stream restoration and slope stabilization project case study

    ‘Gerber Legendary Blades’, a division of Fiskars, is a manufacturer of jack-knives for outdoors enthusiasts. The Gerber corporate headquarters was built in the late 1970’s near Portland, Oregon. The parking lot was built an adequate distance from the stream running through the property, and paved with asphalt. In the late 90’s, continued development of impervious surfaces ...

  • Erosion control and slope stability project case study

    The steep un-vegetated slope at this lakeshore residence was eroding into the lake with every rain event. Record high lake levels combined with wave action eroded the base of the hillside causing severe hillside instability. During heavy rainfall events more and more of the hillside slipped into the stairwell and lake. The residence owner was concerned with preserving the slope, overlook ...

  • Geodrilling: Maintenance of active slope stability installations

    Landslide activity and slope failure on parts of the Isle of Wight have been an ongoing problem for hundreds of years and a significant landslide during the particularly bad winter of 1994-5 seriously affected an area up to 400 metres inland from the coast. Instability in the Castlehaven area had to be addressed to reduce the risk to public safety, property and the local infrastructure. The Isle ...

  • Gaviota pass steep slope, Santa Barbara County, California

    Faced with repair of a severely eroded steep section of pipeline right-of-way on the California coast, engineers determined that GEOWEB Cellular Confinement System was the only system capable of providing a cost-effective and appropriate solution. With a total slope length of 500 feet, a severe pitch of 1:1 and bare rock slope faces, four inch deep GEOWEB was installed in order to “perch” soils ...

  • Geotex® 4x4 used in Missouri slope failure repair project case study

    In 1993, flooding in an adjacent stream caused a slope failure along a 300 foot section of Old Highway 100 in Franklin County, Missouri. Many attempts were made over the years to stabilize the slope and roadway, and none were successful. Flooding caused the slope that supported the highway to give way and become hazardous. A porous concrete slope protection facing was used to cover approximately ...

  • Steep Slope Erosion Control (Punta Raton, Panama) case study

    Background: The hilly Pacific coastline of Panama has witnessed the force of many storms and severe erosion forces in years past, leading to a problem for the Punta Raton Beach Residences. In order to procure the most property out of the available space, contractors have been required to cut into the bordering slopes at a 70 degree angle. Technical ...

  • ADMS 5 Buildings Validation Alaska North Slope Tracer Study

    1 Introduction The Alaska North Slope tracer study1 (see Figure 1) involved 44 hours of buoyant SF$ releases from a 39-in high turbine stack. Tracer sampler coverage ranged over seven arcs from 50 to 3000 m downwind. Meteorological data, including wind speed, wind direction, temperature, sigma-theta and sigma-w, were available from an on-site tower at ...

  • Improvements on a system for soil erosion control of slopes using scrap tyres

    This work proposes improvements on the assembly process of a slope protection system using scrap tyres to reduce severe erosion that occurs in non-vegetated slopes. Tests results during six rain events, with maximal intensity of 26 mm/hr and accumulated rainfall of 94.5 mm, indicate that the installation cost of the system was $1.10USD/tyre and reduced the erosion by 83% with respect to an ...

  • How Strata’s Microgrid reinforced a roadside slope and saved 30-percent in costs

    Challenge The City of Fairfield in Solano County, CA has many beautiful parks and trails enjoyed by residents year round. One of roadways stretching alongside one of these natural areas was threatened due to unstable soils and a failing slope. This posed safety concerns for the area. The roadway had a right of way to a state highway and the county and city were in need of a cost effective ...

  • 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 ...


  • Newtons Cove Coast Protection Scheme

    Using tried and tested techniques, B&V Water River & Coastal Management experts replaced an existing seawall and won an environmental award in the process. The chilled rough waters of the English Channel have pounded and eroded the coast of England for millennia causing present day problems for towns and villages clustered close to the sea since ancient times. In the county of Dorset on ...

  • Articulated Concrete Blocks for Shoreline Protection

    Shoreline erosion is a process that occurs naturally along the coast and on lakes, rivers and even streams. Shoreline erosion can occur slowly due to the constant bombardment of waves against the shore, the flow of water, runoff due to rain and the freezing and thawing of ice. It can also occur quickly due to storms, flooding and other more extreme weather conditions. Shoreline erosion is a ...

  • Retaining wall for riverbank protection (Rio Guayabo, Panama)

    Background: The strong currents of the famous rebel Guayabo River at it’s highest point in the Anton Valley watershed almost destroyed a large area of privately owned land. Constant changes in the water levels has eroded the banks, causing ancient trees to fall helpless into the river’s grasp. The construction of luxury residences “Los Portales” was suspended as ...
