This is why I love to work on projects in #NorthernMichigan. Here you can see the West Arm of Grand Traverse Bay, with the Leelanau Peninsula on the other side. A future home site on Old Mission Peninsula with this view at the bottom of the bluff. What is the bluff made of, you might ask? Well, it's made up of primarily cohesive (clayey) material, containing seams of silt and layers of sand, silty sand, and sandy silty clay, with some boulders from the surface down to approximately 3 feet. The topsoil consists of black organic peat, which is completely saturated in some areas by the groundwater that is seeping out of the slope from the area directly upslope from the bay, and is perched near the ground surface above the highly impermeable subsurface soils.

Address slope stability challenges effectively with soil nailing. This technique involves reinforcing soil with steel rods or nails, enhancing stability and preventing erosion. Ideal for steep terrains and unstable slopes, soil nailing offers a cost-effective, long-lasting solution, ensuring safer and more secure slopes.

Another floodplain excavation and remeander design is in the works.

#DYK - Pinholes, as the name suggests, are minuscule voids about the size of a needle's prick or smaller. They form in debris flow deposits when tiny air bubbles become trapped in the poorly consolidated soil. Unlike rootholes, pinholes can compromise soil stability and lead to potential collapses when wetted under loading. CMT can help you determine if collapsible or other problematic soils are present as part of a geotechnical study prior to construction and provide appropriate remedial recommendations. #CMTeam #GeotechnicalEnginnering #SoilStructure

Hydro excavation is a non-destructive digging method that uses a combination of high-pressure water and an air vacuum to cut through and break up soils.

Liquefaction occurs when soil that is usually stable becomes saturated with water, causing it to lose its strength and stiffness. This can happen during an earthquake or other intense vibrations, when the soil particles are shaken loose and start moving more freely, causing the ground to behave like a liquid. Liquefaction can cause buildings and other structures to sink or even collapse, and it is a significant hazard in earthquake-prone areas. Quicksand, on the other hand, is a type of liquefaction that occurs when water-saturated sand or soil loses its strength and cannot support weight. It is often found near rivers, lakes, and coastlines, where water can saturate the soil. When a person or animal steps on quicksand, it can cause the sand to lose its strength and become like a liquid, causing them to sink or become trapped. In summary, liquefaction is a broader term that refers to the loss of strength and stiffness in soil due to saturation with water, while quicksand is a specific type of liquefaction that occurs in water-saturated sand or soil and can cause sinking or trapping of people or animals. #civilEngineering #engineering #construction #soil #geotech

🏖️ Groynes: Guardians of the Coast 🌊 A groyne, also spelled groin, is a rigid structure built perpendicular to the shoreline, extending from the beach into the water. Typically constructed of rock, concrete armor, steel, or wood, groynes are designed to interrupt the movement of sediment along the coast. The most common construction method involves using specified core fill, under layer, filter layer, and rock armor, tailored to geological and geographic conditions. Groynes are commonly used in erosion control to stabilize beaches and prevent coastal erosion. Their primary function is to trap sediment transported along the coast by waves and currents. By blocking this movement, groynes cause sand deposition on their updrift side. This accumulation builds up the beach, widening it and providing protection against erosion. Additionally, groynes can influence coastal currents, redirecting them and promoting more even sediment distribution along the shoreline, further enhancing beach stability and reducing erosion in specific areas. #CoastalProtection #ErosionControl #BeachStabilization #Groyne #GroyneConstruction #Construction #Coastalengineering #GuardiansOfTheCoast 🏝️🌊

Shoreline Structure Working A tetrapod is a form of wave-dissipating concrete block used to prevent erosion caused by weather and longshore drift, primarily to enforce coastal structures such as seawalls and breakwaters. Tetrapods are made of concrete, and use a tetrahedral shape to dissipate the force of incoming waves by allowing water to flow around rather than against them, and to reduce displacement by interlocking. #wave #oceaneering #structuralanalysis #shoreline #safetyculture #oldisgold
