Lumivyöryverkot

Lumivyöryverkot, also known as avalanche protection nets, are structures designed to prevent or mitigate the destructive force of snow avalanches. They are typically made of strong steel wires or mesh, often supported by robust poles anchored deeply into the mountainside. The primary function of these nets is to arrest the downward movement of snow, breaking up large masses into smaller, less dangerous fragments, or to simply stop the snowpack from accumulating and releasing as a full-scale avalanche.

These systems are commonly installed in mountainous regions prone to avalanches, particularly in areas where human settlements, infrastructure like roads and railways, or ski resorts are located. The design and placement of lumivyöryverkot are carefully considered based on factors such as slope angle, snow accumulation patterns, and the potential impact zone. They work by increasing the friction between the snowpack and the slope, or by creating a barrier that catches the sliding snow.

The effectiveness of lumivyöryverkot can vary depending on the size and speed of the avalanche. While they are a crucial tool for avalanche safety, they are often part of a broader avalanche management strategy that may also include artificial triggering of avalanches, reforestation, and early warning systems. Regular maintenance is essential to ensure the integrity and functionality of the nets, as they are exposed to harsh environmental conditions and significant forces.
