Understanding Atmospheric River Events

Atmospheric river events are long, narrow corridors of concentrated moisture in the atmosphere that transport significant amounts of water vapor from tropical regions to mid-latitude and coastal areas. When these weather systems make landfall, they can cause extreme rainfall, flooding, landslides, and erosion, leading to catastrophic damage to infrastructure, roadways, bridges, railways, and utility networks.

The Geohazard Impacts of Atmospheric River Events

The immense precipitation from an atmospheric river can trigger a variety of geohazards, including:

  • Landslides & Slope Failures – Saturated soils lose stability, causing landslides that can block highways, railways, and access roads.
  • Rockfall & Debris Flow – Increased water runoff can loosen rock formations, leading to dangerous rockfall and debris flow hazards.
  • Soil Erosion & Embankment Instability – Excessive rain can wash away critical soil structures, undermining foundations and creating instability in embankments and slopes.
  • Flooding & Infrastructure Damage – High-intensity storms can overwhelm drainage systems, causing severe flooding and water-related damage to roads, tunnels, and bridges.

How We Can Support Geohazard Mitigation After an Atmospheric River Event

We specialize in rapid-response geohazard mitigation solutions to restore and protect infrastructure after atmospheric river events. Our team works closely with Departments of Transportation, rail companies, power utilities, and general contractors to assess damage and implement effective remediation strategies.

Our Post-Event Mitigation Services:

Spider excavator scaling a steep roadside slope.

We deploy specialized equipment, including spider excavators and rope-access crews, to remove debris and stabilize slopes after landslides.

Shotcrete wall with drainage holes above a rock-covered slope next to a road.We enhance stormwater management with culvert repair, placement, and subsurface drainage systems to mitigate future flooding risks.
