FloodCast: A Framework for

Enhanced Flood Event Decision

magine flood response capabilities being dramatically
improved by instantaneous inundation and water depth
data delivered to smart devices demonstrating exactly
where imminent risks exist. Imagine that information being
delivered to emergency responders, public safety officials and
transportation decision makers who immediately disseminate that
information to the public. Imagine the lives saved from people
knowing where not to go during wet weather events.

As we have seen most recently with
Hurricanes Harvey, Irma, Maria and Nate,
flooding has a significant, damaging impact
on transportation systems and its users.
Many lives have been lost when cars are
swept away by flood waters and drivers
are unable to escape their vehicles in time.
Emergency response and state transportation
agencies often lack the integration of realtime forecast information to incorporate
into their asset management and
communications systems to expeditiously
close roads, bridges, tunnels, etc. and thus to
prevent loss of human life. This information
may consist of now-casts, short-range and
medium-range forecasts being developed by
the National Water Model.

To bridge this gap and improve state
DOT flood planning, risk management,
mitigation, preparedness operations
and emergency response activities, the
National Cooperative Highway Research
Program (NCHRP) initiated a national
research project entitled FloodCast.
The project is overseen by a panel led by
officials from CalTrans and Delaware DOT
and comprised of representatives from
American Association of State Highway
and Transportation Officials (AASHTO),
NOAA, USGS, research universities and
private consulting firms. The research team,
led by Dewberry, an engineering consulting
firm based in Virginia and including Venner
Consulting, is developing a data architecture

and framework for a flood forecasting
decision-support prototype tool to make rapid
response decisions and communicate them
during flooding events to reduce impacts to
transportation infrastructure and its users.

Approach and findings
Several steps were taken before Dewberry
began the framework design. A literature
review identified numerous resources to
support flood forecasting, response and
recovery. Many of these resources could be
readily integrated into a framework to support
state DOTs in planning for, responding
to and operating during floods. Other
resources would require modification before
being integrated into a flood forecasting or
"floodcasting" framework. We determined a
floodcasting framework would need to include
certain components to be effective, which led
to the development of the FloodCast Capability
Maturity Model (CMM) to help state DOTs
define the key data, technologies and practices
required to effectively achieve floodcasting
progress over time. These components or
'capability dimensions' were: meteorology;
hydrology and hydraulics; asset management;
communication and information transfer; and
incident management. These CMM capability
