Nahal Tzipori: Bank Stability & Erosion Monitoring

Drone LiDAR and high-resolution aerial imagery of restored stream segments for the Kishon Drainage and Rivers Authority, with repeat surveys to track erosion and deposition over time.

Location: Nahal Tzipori, Lower Galilee
Status: Ongoing Monitoring
Goal: Map bank instability along the restored channel and compare how different soil treatments protect the banks from erosion.
Data: Centimetre-level orthophoto; sub-metre terrain models
Environment: Restored stream channel, agricultural banks, bridges and riparian vegetation
Duration: 2025 – ongoing

The challenge

After major channel works, the authority needed to know where banks were failing and whether seeding and maintenance treatments were actually reducing erosion. A winter flood reshaped parts of the channel shortly before the survey.

The DynamicSense intervention

We mapped the stream segments with drone LiDAR and high-resolution imagery, separated ground from vegetation, classified land cover and flagged steep, bare banks as unstable. Treatment plots were then compared segment by segment.

Outcomes & decision support

The authority received a quantitative baseline for hydrological and ecological planning, CAD-ready survey data and an evidence-based comparison of bank treatments. The follow-up survey will measure erosion and deposition directly.
