Landslide Monitoring Hörbranz

Hörbranz, Vorarlberg, Austria
Project duration:  November 2023 – ongoing
In the Austrian municipality of Hörbranz, a slope began shifting in late April 2023, causing severe damage to several houses. Despite large-scale soil removal, the ground remains active. Locator One units continuously track displacement, including critical acceleration phases where movement reached up to five meters within twelve hours.

 

Basetime’s GNSS device installed on the slope for Hörbranz landslide monitoring, capturing displacement data to support early detection.
A way to continuously monitor the risk of further damage, helping to prevent additional harm and financial impact, resulting in a safer living and working environment.

Project Purpose

The project aims to monitor all slope movements in real time to detect risks early and support stabilization efforts. The collected data helps local authorities make timely safety decisions and reduce the risk of further structural damage.

Implemented Solution

Six Locator One units were installed at key locations on the sliding slope. High-frequency GNSS measurements provide precise positional and elevation changes. Using Virtual Reference Station support and short logging intervals, the system captures even small accelerations and delivers reliable alerts to stakeholders.
