Yarkon River Topo-Bathymetric Mapping

Drone LiDAR and drone-mounted sonar combined into one topo-bathymetric model of a Yarkon River reach for LIA, supporting planning of the river corridor.

Location: Yarkon River
Status: Completed
Goal: Give planners one continuous, accurate surface from the floodplain and banks down to the riverbed.
Data: Centimetre-level terrain and riverbed model
Environment: River channel, shallow water, vegetated banks and floodplain

The challenge

The river combines vegetated banks, shallow water and restricted access, leaving a gap between conventional land survey and boat-based sonar.

The DynamicSense intervention

We mapped the banks and floodplain with drone LiDAR and the riverbed with a sonar suspended from a drone, then merged both datasets into a single elevation model on one reference.

Outcomes & decision support

The combined model supports planning, hydraulic, erosion and maintenance decisions without treating land and water as separate surveys.
