Flood Management Services

Understand, mitigate and plan for flood events with expert flood monitoring, modelling, forecasting and warning services.
Our flood services help people, companies and public organisations to understand their current and potential future flood risk, enabling them to mitigate and plan for flood events and minimise or prevent damage and disruption to homes, businesses and infrastructure.
Our Capabilities
Flood Warning and Forecasting
We are the leading independent provider of flood warning systems to local authorities in the UK, having installed over 830 flood warning sites for over 75 councils and land drainage authorities. Our systems provide early warning to both drainage authority staff, to deploy maintenance teams, and to local residents, to deploy property level protection or trigger local flood plans.
Flood Risk Assessments
We have extensive experience in undertaking both FRAs and Flood Consequence Assessments (FCAs) for housing, commercial, agricultural, power, leisure and quarrying applications.
Flood Risk Assessments (FRAs) are a formal requirement to support many planning applications. Specific requirements apply in England, Wales and Scotland, but in general, FRAs need to demonstrate whether a proposed development is likely to be affected by any type of flooding and whether it will increase flooding elsewhere.
Flood hydrology and modelling
Flood hydrology entails the calculation of flood peaks or flood hydrographs for observed floods or for design floods for specified return periods. Our expert consultants use UK Flood Estimation Handbook (FEH) methods in undertaking FRAs and in support of hydraulic modelling, enabling us to appreciate situations in which the methods work well and critically, and the conditions in which they require some refinement.
Hydraulic modelling
Our hydraulic modelling services provide accurate estimation of water levels and flood extents for rivers and watercourses. Although UK flood extents are shown on the Environment Agency website, these are often based on the use of generalised models; detailed, site-specific modelling can be used to refine and challenge the flood maps. The models can also be used to estimate flow velocities and the associated flood hazard ratings.
Flood mitigation
Flood mitigation is an essential component of the work that we undertake for FRAs. Mitigation ranges from the design of drainage measures such as soakaways through to the design of flood balancing reservoirs.

Our Hydro-Logic® Smart Monitoring Data Loggers
Get reliable water flow data to enable effective water resources management, hydraulic analysis and flow control monitoring.
Accurate, reliable remote capture of water level, flow, weather and quality data enables engineers, municipal organisations and consultants to carry out critical flood mitigation, water resource planning and long-term environmental research activities.
Monitoring Weather
A comprehensive monitoring network may consist of temperature and precipitation, solar radiation, air pressure, wind, soil moisture, river and oceanic variables.
Rainfall is a prime upstream indicator of potential flood risk, and monitoring systems that measure climatic factors such as this can provide insight into imminent flood events. However, rainfall alone does not take into account contributory factors such as ground water, river levels or (in some regions) snow melt.
As such, while meteorological measures might provide an indicator of probability of flooding, they may be insufficient on their own to provide accurate, location-specific flood warning and should therefore be factored into a more comprehensive monitoring network.
The ability to monitor current and trending weather variables is especially important for the management of water resources and rainfall is just a single factor. The effects of wind, sun, changing pressure, humidity, etc. all play a part and these data are important components of a comprehensive management system.
River flow - this is calculated using a distributed rainfall-runoff model using the output from the rainfall model.
Monitoring for droughts - one of the most important uses for rain gauges is to monitor droughts in areas reliant on agriculture, as well as cities that don`t get much rain.
Monitoring for floods - this is often used in conjunction with level to create a catchment model.
Monitoring Water Levels
River level is the depth of water at a monitoring station, measured in metres to a specified datum.
A good indicator of flood risk are the water levels in natural and man-made bodies of water such as rivers and sewers. These water levels represent a tangible, realistic measure of the volume of water that is being conveyed downstream, and can provide accurate signals as to likely flooding.
Monitoring watercourses like these upstream of homes, businesses and infrastructure provides a reliable measure of flood risk, and water level monitoring systems can form the core of an effective flood warning system.
Monitoring Flow
Flow is the volume of water passing a monitoring site, measured in cubic metres per second. Flow can be measured directly or derived from continuous measurements of river level and water velocity.
River flow forecasting is very important as a basis for early flood warning
As flow is a function of river level and velocity it is possible to get different values of flow for the same level. This can happen if the characteristics, for example, roughness of the channel, change as the result of a flood or from the growth of vegetation.
Monitoring Water Quality
Effective water quality monitoring is the key to environmental protection of watercourses and for reliable process control and wastewater treatment. Discharge consents under EPR regulations dictate that water quality monitoring is undertaken to ensure that consented parameters are below the consented concentrations.
Traditionally this has been done using water quality sampling methods, but increasingly automatic water quality measurement sensors linked to real-time telemetry is seen as the most reliable and timely means of ensuring that treatment processes are operating efficiently and that EPR compliance is maintained.
Hydro-Logic® Flexi Loggers
We have three types of Hydro-Logic® Flexi logger and they each have attributes that can make them ideal for some applications and not others. Please use the table below to choose the logger that`s right for you:

Hydro-Logic® Flexi Logger 100

Robust to IP68 standard, the Hydro-Logic® Flexi Logger 100 is ideal for installation into remote or space constricted applications

Hydro-Logic® Flexi Logger 200

Hydro-Logic® Flexi Logger 300Ex

ATEX certified, the Hydro-Logic® Flexi Logger 300Ex is ideal for installation in chambers or tanks where a potentially explosive atmosphere may be present.
Telemetry
Automatically process and manage hydrometric data to provide alarms and early warning of flood events and other environmental risk factors.
Hydro-Logic telemetry systems provide an online platform for basic data visualisation, inspection and early warning on an annual subscription.
Automatically receiving data from remote Hydro-Logic® data loggers, Hydro-Logic® telemetry systems provide an interface to enable you to inspect data outputs, helping you to identify potential system blockages and alerting you to changes in environmental conditions that could indicate an imminent flood event.
Hydro-Logic® telemetry systems also manage any automated alerts that have been configured, distributing them via e-mail or SMS to designated recipients to provide early warning of flood events or other environmental risks.

Hydro-Logic® Timeview

Hydro-Logic® Timeview provides automatic wireless receipt of data from remote sensors, triggering automated flood event alarms, providing short-term data storage and enabling data visualisation and initial analysis.
