"We were impressed by the speedy, well-informed service and personal contact that we received. The report was thorough and comprehensive. We will certainly use GeoSmart's services in the future"

The UK’s first early warning system on groundwater flooding for property, infrastructure and public service providers.
As our climate changes, so do threats from flooding to where we live, work and run essential services. Groundwater flooding has been the least understood risk – until now. We have launched GWFlood to help you plan and take action to safeguard property and ensure continuity of essential services.
Combining 50 years of borehole data, hydrogeological expertise and live telemetry feeds, our unique modelling tracks actual borehole levels, weather forecasts and maps risk predictions up to 90 days in advance.
For more information on our unique GWFlood contact us today.
We update our forecast every working day. This is sufficient when there are no imminent groundwater flooding incidents. If incidents are likely, or are occurring then we increase the service to daily, then twice daily. A weekly synopsis of the outlook for groundwater flooding is prepared by our experienced hydrogeologists in support of the daily forecasts.
Forecasts are provided on a regional scale for river catchments and sub-catchments. If you are interested in a particular community, or assets then the forecast can be delivered for each.We send you:
We send the daily forecasts by email, which will include a link to download the forecast as a data file and catchment risk map. We also provide a web mapping interface.
A weekly synopsis report is provided reviewing the outlook and current groundwater situation with accompanying forecast groundwater hydrographs. The potential impact and duration of groundwater flooding events is reviewed as part of the report.
We currently deliver as csv files (one line for each catchment), ESRI shapefiles, and PNG images. In addition the web mapping interface gives a spatial overview of the forecast. Other file types can be delivered on request.
Our standard forecast is delivered for 302 river catchments across southern and south east England (soon to be c. 500 catchments from southern England to Yorkshire). But if you have a particular asset, community or location we can provide a specific forecast.
Yes – for a small set-up fee in addition to the annual licence we can enter your location into the system and generate a daily forecast for your specific location, community or asset.
A base map is used to highlight the forecast for groundwater flood-prone river valleys. The GeoSmart Groundwater Flood Risk Map can be used in tandem with the forecasts to highlight the particular locations within a catchment that might be at risk.
The GeoSmart groundwater forecast model combines historic climate and borehole data plus live telemetry feeds and daily updates of the most accurate ensemble weather forecasts. Predicted groundwater levels are used to map risk predictions over a range of time scales for 5, 15, 30 and up to 90 days in advance. As with any weather forecast the uncertainty in the predictions increases with the extent of forward prediction. Results indicate the percentage likelihood that groundwater flooding will occur within the prescribed time period and potential flooding duration.
Threshold levels are set relative to the forecast groundwater elevations to indicate the likely onset of groundwater flooding. Where required additional threshold levels can be set by the client for specific assets or communities.
