FloodArea for ArcGIS
GEOINTELLIGENCE AND BEYOND

FloodArea in ArcGIS ®
FloodArea is a 2D flood modeling tool for
the delineation of inundation areas –
completely integrated in ArcGIS. Since the
first release in 2001 numerous engineer-
ing companies, research institutions, and
public authorities (municipal to national
level) of about 20 countries have confi-
dence in this simulation model.
Main functions
Fully integrated in ArcGIS Desktop Applications
(including Model Builder, command
line, and scripting)
Specification of elevation units of your
choice
Model input either by spatially variable
water level or by hydrograph
Easily create and start simulation animations
from within ArcMap
Full consideration of dam failures and
flow barriers
Save intermediate results at intervals of
your choice

Manage and present your Metadata with
a separate FloodArea style sheet
Hydrodynamic Modeling

Algorithm
Hydrodynamic approach
Correct mass balance
Automatic optimization of the iteration
time step during model runs
Distance weighted distribution to all 8
neighboring raster cells
Dynamic change of flow direction
Consideration of roughness coefficients
Edges are considered
Application examples
Delineation of inundation areas from
flood marks
Dam failure scenarios
Flood simulation for risk analysis and
disaster management
Estimation of flood retention potentials
FloodArea HPC -
High Performance Computing
Modeling flooding scenarios using high
resolution terrain models demands highest
computational performance. Common
practice is to overcome this problem either
by modeling sub-sections of an area or by
using a lower resolution. In the FloodArea
Desktop-version performance is limited by
available workstation memory.
These limitations are now a matter of the
past. Since FloodArea-HPC has been introduced,
any number of computers (nodes)
can now be combined to a computing cluster,
whatever the size of your study area
demands. You can increase the memory
virtually to any size and according to your
needs. You can now easily run simulation
models with 500 million raster cells or
more.
In addition to this, FloodArea HPC has
been improved by optimizing its algorithmic
core. FloodArea HPC supports
Multi-Threading and thus makes full use of
modern Dual- or MultiCore systems, which
further dramatically decreases computation
time. The operational, near real time
simulation of dam or levee failures is now
possible.
Support of additional operating systems
FloodArea HPC computing clusters can
comprise of computers running Windows
(XP, Vista), Linux, and Solaris.

If you don’t want to build up your own
computing resources or if you want to
save time for solving other problems think
about outsourcing model runs to geomer.
You can benefit from our experience and
get best possible results efficiently.
DTM Tool –
Editing and manipulating terrain models
DTM-Tool is set of tools for working with
digital terrain models, focusing on their hydrological
and hydraulic properties. DTM-
Tool is the ideal companion for FloodArea.
