The Flood Intel Platform

The tools you need to prepare and take action to prevent flood impacts.


Combining world-leading technologies

Three core services, combined into one powerful, easy-to-use tool.

The only platform of its kind, Previsico's solution is driven by a growing need to prevent pluvial flooding from catching people off guard. The world's most advanced technologies, brought together to protect homes, businesses, and entire communities across the globe.

Decision support tools

Flood Intel dashboard

  • Interactive map displays the forecasted time and depth of your property/assets' flood risk. Customers can view live sensor analytics to monitor actual flood risk and on-site sensor performance.

  • Real-time asset risk scoring provides real-time risk scores for your assets.

Email warnings

  • Immediate notifications up to 48 hours in advance to enable you to proactively manage flood risk.

  • Warnings can cover both property point locations and wider areas (polygons) that highlight forecasted depth, time and duration of flooding as well as critical sensor threshold.

Flood Intel API

  • Integrated data from our Flood Intel Platform feeds into your own risk management tool via API for a centralised, easy view of risk.

  • All data feeds are available via API (point, polygon and mapping data).

The technology

Live hydrodynamic modelling at scale

Our forecasting system continuously generates flood forecasts at the property level, taking into consideration the latest weather nowcasts and forecasts and antecedent conditions derived from observed rainfall.

At the core of our forecasting system is a bespoke hydrodynamic modelling suite designed for accurate real-time flood forecasting. The system utilises the latest cloud computing technology and generates high-resolution property-level forecasts at scale.

The service continuously, and uniquely, re-runs the model all year round, generating event specific forecasts to warn of flooding at property level up to 48 hours in advance.​  

This leverages leading data sources such as hyperlocal rainfall forecasts, sensor derived water levels, antecedent condition, local drainage, topography, land cover, soil and geology to produce fast and accurate representations of flow routing across entire geographies. 

On-site sensors

We use state-of-the-art, easy-fit, connected hydrological sensors (e.g. level, velocity) uniquely designed for real-time monitoring of different hazards, including rapid-onset events occurring above (e.g. riverine, coastal, and intertidal environments or screened culverts) or below ground (e.g. surface water and wastewater drainage networks).

The need to regularly change batteries and/or calibrate sensors when sampling in real-time and at potentially high frequencies over protracted periods renders most commercially available solutions financially unsuitable for long-term monitoring/alerting applications without regular (costly) maintenance. Our technologies overcome these issues, combining Over-The-Air power planning and dynamic sampling to support up to 5+ years battery life, even when submitting data packets at high frequencies.

Enhanced diagnostics are provided with each reading, meaning the data can be verified in real-time, removing the guessing game that currently exists around measurement reliability in environmental monitoring.

Case study

How Whalley Prevented 100% of Their Flood Losses

Read our Lloyd's Lab Report

As part of our participation in the Lloyd’s Lab, we developed a framework to support underwriters in improving their loss ratios by considering the ‘preventability’ of flood losses.

This is fully outlined in our Lloyd's Lab report which is free to download.
