The full scope of flood hazard management

Flood risk management is incredibly challenging because “a flood” isn’t just one predictable hazard that plays by the same rules in every scenario. Click the circles on the map below to learn more about how flooding presents unique challenges in different settings and contexts.

Arid / semi-arid terrain

Flash floods develop incredibly quickly in dry, arid, or drought-ridden areas because the soil cannot absorb rainfall properly.


In areas where wildfires, logging, or development have reduced trees, floodwaters can rapidly reshape the land in undesired ways.

Dams / Reservoirs

Major infrastructure is susceptible to overtopping and potential failure when owners and operators don’t manage with extreme rainfall events in mind.

Rivers / Streams

Rainfall or snowmelt can overwhelm small waterways, leading to backup and flooding in urban, suburban, and rural communities.

Metropolitan areas

Heavy rainfall can overwhelm urban stormwater and wastewater infrastructure, leading to streets and homes flooding.


Floods can endanger livestock, wash soil away, and spoil crops by promoting mold growth, impacting the food supply.


Over half of all flood-related drownings occur when a vehicle is driven into hazardous flood water.


Tidal storm surge, river flooding, and multi-day storms can all cause levees to fail from strain or become overwhelmed by rising waters.

Coastal flooding

Tidal storm surges and tsunamis can cause rapid flooding in communities where the land meets the sea.

Our approach to flood early warning systems

An ideal flood warning system is complex. At AEM, we use a framework that expands upon the internationally accepted four pillars of flood warning systems. Click through the steps of the cycle to hear how some of our top knowledge leaders explain our approach:

1. Flood risk knowledge

Every early warning system needs to begin with an understanding of where flood risks exist, which conditions or scenarios could create flooding, what property or infrastructure could be in danger, and exactly where water will go during a flood event.

2. Monitoring & forecasting

Hydrological and atmospheric models provide a critical lens for understanding the precise relevance of the various data points and their likely impact on flooding. To provide even more lead time, a flood warning system should also look at forecasted values for key variables like rainfall and water levels.

3. Hazard communication

To lead an informed flood response, local leaders need to be able to communicate with a variety of stakeholders, from political and business leaders to emergency responders and everyday citizens in harm’s way. Great communication requires accurate data, timely delivery, and clear messaging.

4. Response management

Once a potential hazard has been identified, it’s crucial to be able to turn data into action to lead a strong response. With that said, outstanding response requires a combination of timely, event-specific inputs and detailed, well-understood emergency management protocols.

5. Continuous re-evaluation

Every flood provides an opportunity to examine what went right and what went wrong, so flood warning system managers need to re-examine each event after the fact and look for lessons that they can apply to the next flood. Through this kind of iterative improvement, a flood warning system can get better over time.

Resilience in Action

We’re proud to be empowering communities around the world to survive – and thrive – in the face of escalating flood risks. Here are some examples of communities that have addressed their unique flood challenges with help from AEM:

Case studies
  • 1. Raleigh, North Carolina
  • 2. Doña Ana County Flood Commission, New Mexico
  • 3. Charlotte-Mecklenburg County
  • 4. Bureau of Indian Affairs Safety of Dams Program
  • 5. Fortune 500 Mining Company
Raleigh, North Carolina
  • Lack of visibility into rainfall between gauges
  • Hourly updates from the field were insufficient for flood warning
  • Needed to predict the impact of rainfall based on forecasts


Gauge-Adjusted Radar Rainfall (GARR) – GARR data enables Raleigh Stormwater to see exact real-time rainfall for any point in the city, eliminating blind spots.

Hydrologic modeling – Modeling increased Raleigh’s understanding of its flash flood-prone urban creeks, creating a reliable framework for decision-making.

72-hour advance flood forecasts – Multiple rainfall forecasts based on quality modeling create a reliable view for up to three days into the future, enabling better preparedness.

Doña Ana County Flood Commission, New Mexico
  • Limited and outdated flood warning systems
  • No shared data view for numerous collaborating agencies
  • Response times slowed by lack of integrated data


Data collection software – Our software provides the Doña Ana County Flood Commission with a real-time centralized data hub for precipitation monitoring and flood risk management.

Sensor network design – Doña Ana County created a real-time weather and precipitation monitoring network for key sites across their county using ALERT2 framework.

Field services & maintenance – AEM brought the county’s planned network to life, installing all gauges, training local stakeholders, and providing ongoing maintenance.

Charlotte-Mecklenburg County
  • Fragmented flood monitoring and water quality data
  • Limited alerting capabilities for Storm Water Services
