Flood Warning

Crucial Flood Warning Data

There is an urgent need to improve flood preparedness as the intensity and frequency of precipitation events
escalate as a result of climate change. Early flood warning systems provide timely data to alert stakeholders and
communities of potential flood events.

Data- Driven Flood Prediction

Have you heard the term 1 in 100 year flood? That means that if
my house flooded last year, it won't happen again for 100 years,
right? Not exactly... This is a common misconception. In reality, a
100 year flood means that experts estimate a 1 in 100 (1 percent)
chance in any given year that a flood will occur.

Flood maps show how likely it is for an area to flood. Continuous
data combined with historical records are used to generate flood
plain maps. The better data on the body of water, the more
accurate the delineation. This information gives insight into the
risk level in order to mitigate damage to property and strategize
new developments.

As time goes on, experts are finding that these predictions and
flood zone designations may need to be revised to reflect higher
risk, thus influencing development and insurance need in nearby
communities. Data-driven decisions such as these require realtime
meteorological and hydrological insights.

Establishing Post- Wildfire Flood Monitoring

After the Spring Fire devastated some 109,000 acres and increased the likelihood of water run-off into the town of La Veta, Colorado (USA) it became necessary to know when a flood event was approaching to give citizens enough time to evacuate.

Learn how the team in La Veta started collecting critical water data, which allows them to see when water from multiple areas is rising to a dangerous levels in order to alert citizens.
