What Hydroremote delivers, and who for.
Hydroremote works at the intersection of Earth observation, environmental monitoring and numerical modelling. Engagements range from a one-off remote-sensing assessment to multi-year monitoring programmes and decision-support modelling for restoration.
1. Remote sensing of water quality
Satellite-derived water quality for lakes, reservoirs, estuaries and coastal waters — for sites that have never been monitored, and for reconstructing history at sites that have.
- Chlorophyll-a, cyanobacteria risk, water clarity / Secchi depth, suspended sediment, turbidity and lake surface temperature
- Sensors: Landsat (1999–present), Sentinel-2, Sentinel-3 OLCI, MODIS
- Whole-of-region mapping (tens to hundreds of lakes at once) and long-term trend analysis
- Optical water-type classification to match the right algorithm to each lake
- Algorithm development, atmospheric correction and ground-truthing
2. Monitoring & high-frequency sensor data
- Buoy and sensor network design, siting and commissioning support
- Processing pipelines for high-frequency data — QA/QC, gap-filling, flagging
- Trend detection and state-and-trend reporting against NPS-FM / NOF attributes
- Integration of remote sensing with in-situ records for cross-validation
3. Lake & catchment modelling
- Coupled hydrodynamic–ecological models (GLM-AED, 1-D and 3-D) to simulate temperature, stratification, oxygen, nutrients and algae
- Scenario testing: nutrient load reduction, inflow diversion, aeration, fish biomanipulation, climate change
- Catchment nutrient load estimation and regional load-target setting
- Decision-support framing so non-specialists can weigh options
4. Machine learning & data products
- Multi-task and transfer-learning models for water quality where in-situ data are sparse
- Custom dashboards and reproducible reporting (R / Shiny / Quarto)
- Data-deficient-lake assessments at regional and national scale
