Project Case Study River Health Intelligence
The River Thames.
A new era of river health intelligence.
From catchment-scale environmental science to accessible, location-specific water quality and flow forecasts — helping communities better understand their rivers.

Forecast horizonDaily insights · Five-day forecasts
Science, connected to everyday life
The whole catchment.
Your stretch of river.
Aquascope and its scientific partners have developed an operational river health forecasting capability for the Thames, combining advanced hydrological and water-quality models with environmental observations to deliver daily insights and five-day forecasts directly to users’ phones.
Technology: Integrated hydrological modelling, water-quality forecasting, environmental observations and mobile delivery.
01 / The challenge
Understanding river health shouldn’t require a scientific degree.
Rivers are dynamic systems. Water quality and flow conditions change with rainfall, land use, agricultural activity, wastewater inputs and seasonal ecological processes.
Yet communities often rely on infrequent sampling, historical measurements or fragmented information to understand conditions in their local river.
For recreational users, citizen scientists and local communities, this creates a significant information gap between what is happening in the river and what they can understand and act upon.
The challenge is not simply collecting more environmental data. It is making reliable, timely scientific intelligence accessible where and when people need it.
02 / The solution
Catchment-scale science. Intelligence at every river location.
Aquascope brings together process-based hydrological and water-quality modelling, satellite observations, in-situ monitoring and environmental datasets within a single forecasting platform.
Spatially distributed intelligence across the Thames study area allows users to explore water quality and river flow at modelled locations through an accessible web and mobile interface.
Live operational insights and forecasts
Access regularly updated conditions and forecasts extending up to five days ahead, supporting better-informed river use and planning.
Accessible on any device
Intuitive desktop and mobile interfaces make sophisticated environmental information accessible to non-specialists.
03 / Making river health understandable
From complex data to clear, meaningful guidance.
The project combines detailed environmental data with a user-focused approach to interpreting river conditions. Two complementary indicators are intended to make river intelligence more accessible.
Intended indicator · Development concept
Health Risk Indicator
Helping recreational users understand changing river conditions.
Designed to communicate potential health-related risks using relevant environmental evidence, including:
- Pathogen-related water-quality conditions
- Potential harmful algal bloom risks
- High river flows and changing hydrological conditions
- Pollution events and changes in water quality
Environmental risk guidance is not a guarantee of water safety or a replacement for official bathing-water assessments.
Intended indicator · Development concept
Ecosystem Health Indicator
Understanding the pressures affecting aquatic ecosystems.
Designed to provide an integrated view of river ecosystem stress through:
- Nutrient enrichment
- Dissolved oxygen conditions
- Organic pollution
- Phytoplankton activity
- Hydrological stress
04 / Environmental signals
Multiple environmental signals. One integrated understanding of the river.
Phosphates / soluble reactive phosphorus
Excess phosphorus can fuel algal growth and put pressure on aquatic ecosystems.
Nitrates
Nitrogen from land and wastewater can contribute to nutrient enrichment in rivers.
Ammonia
A form of nitrogen that can be harmful to aquatic life at elevated concentrations.
Dissolved oxygen
The oxygen available in water helps sustain fish and other aquatic organisms.
Biochemical oxygen demand
Indicates the oxygen used as organic matter breaks down, revealing a pressure on river life.
Phytoplankton activity
Changes in microscopic algae help explain ecological responses to nutrients, light and temperature.
Pathogen-related indicators
Modelled pathogen-related conditions can inform risk interpretation.
River flow
A core hydrological variable influencing pollutant transport, dilution and habitat conditions.
These variables describe the scientific scope of the approach. Sources, update frequencies and forecasting validation differ by parameter; not every variable is directly or continuously measured. Temperature also informs the interpretation of changing river conditions.
Parameter-specific validation results

06 / Scientific foundation
Research-led. Operationally focused.
Aquascope’s forecasting approach builds on established process-based hydrological and water-quality science, integrating environmental observations and modelling to understand how conditions evolve across river catchments.
The platform’s scientific foundation is supported by peer-reviewed research and collaboration with specialists in hydrology, water resources and environmental sensing.

Aquascope’s value lies in integrating complementary sources of environmental intelligence into an operational, scalable platform. The Thames project brought static models, satellite and sensor data together and automated their delivery through a single forecasting system.
07 / Public access and community impact
Putting river intelligence into the hands of communities.
The Thames project demonstrates how advanced environmental science can be translated into an accessible public-facing service. Its community-focused approach is intended to:
- Translate complex environmental signals into understandable guidance
- Support recognition of pollution events, including those not directly driven by rainfall
- Help users interpret changes in river conditions
- Incorporate and guide quality-controlled citizen science observations
- Strengthen environmental awareness and community participation
- Support more informed decisions about recreational river use
- Encourage positive river stewardship
Designed to empower communities.
08 / Wider application
A model for river intelligence beyond the Thames.
The Thames deployment illustrates the potential for a scalable, catchment-based approach to environmental intelligence.
The same underlying principles can support monitoring and forecasting across other catchments, connecting environmental science with the operational needs of communities, water managers and organisations responsible for water and natural assets.
Communities
Accessible environmental information and greater awareness.
Water managers
Improved understanding of catchment processes and changing water-quality conditions.
Environmental organisations
Evidence to support restoration, monitoring and community engagement.
Asset owners
Insights into water-related pressures, ecosystem services and environmental risk.
The original Thames project launched the Aquascope Beta platform, delivering daily indicators for oxygen, nitrates, phosphates, flow, temperature and pathogens, with five-day forecasting capability. It provided early proof of scalability across selected UK catchments.
