Recent flood events have raised the profile of flooding, from all sources. At DHI, we
truly believe the solution to flooding should not be dictated by the choice or
capability of the modelling software. Instead the modelling software should be used
to inform and test possible solutions, at a catchment scale. Our integrated modelling
software can consider flooding from all sources in an integrated way, as well as
considering, for example, the movement of a pollutant, through a pipe system, as it
spills overland and is transported away through a watercourse. Sub-surface
interactions are also included as our integrated modelling software allows the
exchange between pipe networks and groundwater to be modelled, not simply as a
gain/loss to the system, but in a fully integrated way.
DHI is a pioneer in the development of truly integrated water modelling software.
Today, our software is unrivalled with respect to flexibility, accuracy and
performance. This allows truly integrated modelling to be undertaken, going beyond
hydrodynamics.
The MIKE by DHI product family encapsulates more knowledge and covers a wider
range of water modelling needs than any similar products. Our software tools are
used by professionals in 140 countries across all continents. They are also
available in many sizes, flavours and languages – and most recently also in the
cloud. Getting access to our global knowledge has never been easier! Crucially our
software is supported locally, by technical experts who have many years of
consultancy experience. MIKE by DHI represents more than 50 years of research
and practical experience – right at your fingertips. We help make you the expert in
water environments.
MIKE URBAN— INTEGRATED CATCHMENT MODELLING

MIKE FLOOD
MIKE FLOOD is the most complete toolbox available for flood
modelling. It allows you to combine a wide selection of 1D and
2D flood simulation engines, enabling you to model virtually
any flood problem. MIKE FLOOD offers a fully dynamic and
integrated coupling between urban and river 1D engines and
the 2D overland flow engine. This solution provides the full
flexibility and capability for investigating complex problems.
MIKE FLOOD is applicable at any scale from a single parking
lot to regional models. Independent studies show that you can
save months of effort and create more reliable models by
upgrading from standard 1D modelling to MIKE FLOOD.
Typical MIKE FLOOD applications include:
 Integrated urban drainage, river and coastal flood
modelling
 Rapid flood assessments
 Flood hazard mapping
 Flood risk analysis for industrial, residential or cultural
heritage areas
 Flood contingency planning (for example, planning of
evacuation routes and priorities)
 Impact assessments of climate change issues
 Flood defence failure studies
MIKE FLOOD features:
1D Engines
 1D river network (MIKE 11)– based on DHI’s classic
hydrodynamic engine for rivers and open channels.
 1D sewer network (MIKE URBAN) – based on DHI’s
equally classic engine for sewer and drainage
networks.
2D Engines
 Single Grid – the classic rectilinear model. Easy to set
up and easy input/output exchange.
 Flexible Mesh (FM) – maximum flexibility for tailoring
grid resolution within the model.
A range of structures (including culverts and weirs) can be
handled both in the 1D and the 2D engines. In addition,
operational structures can be included in the 1D networks
using add-on modules.
The 1D river and sewer engines and the 2D overland flow
engines can be coupled to provide fully dynamic and
integrated modelling to meet your most complex project
requirements.

LOCAL AREA WEATHER RADAR (LAWR)
DHI has developed a short range weather radar (LAWR)
to detect the spatial variation of local rainfalls. This is
useful for providing rainfall forecasts with a few hours
warning and high resolution rainfall data.
The radar measurements may be presented as time
series of rainfall for specific catchments or as graphical
images of the full radar coverage. This information can be
broadcast to the web in real-time. DHI’s weather radar
can also be combined with its urban drainage models and
thus provide an integral part of urban information and
flood management systems.

URBAN FLOODING
Today's demand for accuracy often calls for using a 1D pipe
flow model combined with a 2D overland flow model. MIKE
FLOOD offers such a model combination through the coupling
of MIKE URBAN and MIKE 21.
MIKE FLOOD efficiently simulates any cause of urban
flooding, including heavy local rainfall, insufficient flow
capacity of storm water inlets or the drainage network, and
flooding caused by overtopping of nearby river or coastal flood
defences.
An unrivalled dynamic coupling of MIKE SHE (our unsaturated
zone model) with MIKE URBAN is also available, allowing the
accurate modelling of the two-way interaction between pipes
in the ground and the surrounding aquifer. This facilitates the
modelling of infiltration to and leakage from pipes as well as
the potential side effects of infiltration prevention.
RIVERINE FLOODING
MIKE FLOOD is an efficient and flexible tool for river flood
modelling when investigating flood hazards and flood risk from
rising water levels in the river/canal system and/or from high
rainfall intensity in the catchment area.
Flooding can be investigated on multiple scales. These range
from large scale basin areas to local impacts in specific low
lying flood prone areas along the river.
When simulating river flooding, the combination of a 1D open
channel model using MIKE 11 and a 2D overland flow model
using MIKE 21 is typically preferred. MIKE 11 and MIKE 21
can be coupled either at specific points or distributed along
entire river stretches on either side of the main river channel.
COASTAL FLOODING
MIKE FLOOD is ideal for efficient and accurate assessment of
coastal flood risks, whether they are related to flooding of
coastal cities and infrastructures, or to the inundation of
reclaimed or low lying areas.
GOING BEYOND HYDRODYNAMICS
For more than a decade, MIKE FLOOD has offered complex
and flexible features for coupling 1D and 2D hydrodynamic
models. Flood extents and flood hazards have been some of
the key issues for flood risk management. These issues will
still be the focus for many modelling applications in the future.
However, in order to support wider EU Water Framework
Directive objectives, there will be a need for more detailed
studies – particularly water quality assessments.
MIKE FLOOD now offers the option to simulate the transport
and spreading of pollutants during a flood event. This is done
via a fully dynamic coupling of the Advection Dispersion
modules of MIKE 11, MIKE 21, and MIKE URBAN.

If you need more PCs to run models, users with a valid
service agreement can access, at preferential rates, more
MIKE software and virtual PCs in the cloud through our
MIKE by DHI SaaS portal. The portal can be used not
only for modules you already own but also for modules
you are considering buying or that you only need for a
brief period of time.
USING MIKE FLOOD AD TO MODEL POLLUTED
FLOOD WATERS AND RIVERINE WATER QUALITY
MIKE FLOOD now includes the option for a fully dynamic
1D-2D Advection Dispersion coupling, which increases
the range of applications substantially.
The new AD coupling in MIKE FLOOD enables users to
simulate new interesting aspects such as: -
 The impact on concentrations of river pollutant in case
of a release from an urban Combined Sewer
Overflow.
 Floodplain contamination from polluted rivers.
 Impact assessment on river quality from pollutant
sources in flood prone areas during flood events.
MIKE FLOOD AD can be further enhanced by ECOLab
for advanced water quality simulations.
ECOLAB
ECO Lab is the complete numerical laboratory for water
quality and ecological modelling. You can develop exactly
the model you need and describe the processes you wish.
No ecological problem is too simple or too complicated for
ECO Lab:
 Open Equation solver for coupled ordinary differential
equations.

GROUND WATER AND PORUS MEDIA
FEFLOW is our state-of-the-art integrated groundwater
software package. It is used for the modelling of fluid flow,
transport of dissolved constituents and heat transport
processes in the subsurface. FEFLOW could be used to
simulate the regional groundwater flow in the capture zone of
a water supply well. FEFLOW excels at groundwater-surface
water interaction. However, FEFLOW is not only a powerful
tool for groundwater modelling. It is also a very general
simulation tool for a wide range of problems involving flow and
transport of contaminants or heat in porous media. FEFLOW
is also used extensively for the modelling of contaminants
from abandoned mines and for the simulation of geothermic
energy systems.

DHI BATHING WATER FORECAST SERVICE
Aarhus is Denmark’s second largest city, with 310,00
inhabitants. The Aarhus project was a forward-looking
one and was a co-operation between Aarhus Municipality
and Aarhus Water. The project consisted of three
phases: analysis and design (2006-2007), implementation
of infrastructure (2007-2012) and integrated model-based
control and warning (2009-2013).
At the analysis and design stage, the project aim was to
forecast the water quality in the harbour and optimise the
capacity of the drainage system and the wastewater
treatment plants. At the implementation stage, 50 million
EUR was invested in infrastructure (consisting of retention
basins, disinfection at WWTP and basin and increased
hydraulic capacity at WWTP) and an optimised control
system (consisting of integrated real time modelling/
control of sewer system and WWTP and an early warning
system). The project has delivered hygienic bathing water
in Lake Braband and in the harbour and improved water
quality in the River Aarhus. The bathing water forecast
service provides the public with information on bathing
water quality via an App and a web-based public warning
system.
