Feturing: Echoes in the River

Explore the immersive underwater soundscapes with recordings of aquatic habitats throughout the UK - from the Norfolk Broads to Lough Neagh - recorded using Thurn’s uPAM systems, featuring our high fidelity hydrophones.

We are developing a cloud-based Artificial Intelligence (AI) and Machine Learning (ML) system to analyse uPAM recordings by categorising and quantifying sounds from species in both freshwater and marine environments to provide insight into ecosystem health.

UPAM is a light-touch, low-cost and non-invasive method for monitoring habitats over extended periods. This enables before, during, and after analysis to quantify impacts on biodiversity from diverse factors ranging from human activity to climate change.

The exhibition has been developed through the Water Restoration Fund Broads Catchment Partnership Development Plan in partnership with Norwich University of the Arts, the Broads Authority and the River Waveney Trust.

The UAWOS project

Combining Drone based Hydrology and Hydrography with Satellite Altimetry

Uncrewed Aerial Water Observation Systems (UAWOS) is an ongoing EU Horizon project which has successfully developed the technologies and methodologies required to measure water flow and estimate river discharge at remote, ‘virtual stations’ using UAV/drone-carried water sensing equipment and satellite altimetry.

In a nutshell: UAWOS combines the measurements of:

  • Surface velocity
  • Bathymetry
  • Water elevation (stage) and slope

This establishes a relationship between water level and river discharge, known as a ‘rating curve’. As water levels change (e.g. in response to extreme weather events), satellite altimetry can be used to remeasure the water surface elevation and estimate the river discharge in near real-time – only limited by how frequently the satellites pass overhead and how quickly data can be downloaded.

As UAWOS project partners, Thurn are exploring how we can bring this technology into wider adoption in order to:

  • enable mapping and modelling of river discharge in remote locations previously considered impossible or prohibitively challenging to observe;
  • accurately estimate river discharge as surface levels change, potentially allowing advanced warning of flooding downstream.
