1 INTRODUCTION
RiverFLO-2Dv3is a hydrodynamic and mobile bed finite element model for rivers. It can route floods and simulatechannel bed changes at high resolution and with remarkable stability. The use of adaptive triangular meshes enables
the flow field to be resolved around key features in complex river environments.
RiverFLO-2Dv3Argus ONE Edition user interface is based upon Argus Open Numerical Environment (Argus ONE).This GIS-integrated software system provides interactive functions to generate and refine the finite element mesh. It
also facilitates assigning boundary conditions and roughness values. By importing and exporting multiple GIS
layers, the user can graphically display the model results in a number of formats.
RiverFLO-2Dv3computation engine uses an efficient and stable finite element solution method that eliminates theboundary and hot start difficulties of outdated 2-D finite element models. This version has more than 100 new
features and improvements, including hydraulic structures such as culverts, weirs, bridge piers, and internal rating
tables.
This users guide provides instructions to install the RiverFLO-2Dv3model, creating your first project, refining yourmodels and explains the fundamentals of the model and its components, as well as the numerical methods used to
solve the governing equations.

2 INSTALLING RiverFLO-2D v3 - Argus ONE EDITION
This RiverFLO-2Dv3uses the well-established Argus ONE graphical interface software (www.argusone.com)as apre-processor to facilitate data input and display results. Argus ONE provides a user friendly GIS environment,
automatically linking the physical data in GIS layers to mesh nodes and elements. Regenerating the computational
mesh does not require re-entering the baseline data such as bed elevations, roughness coefficients, or boundaryconditions. The software provides a variety of mesh generation options to optimize the mesh creation around
complex river features. This enables the model to resolve difficult flow issues in a rapidly varied flow field.
Creating a RiverFLO-2Dv3project is relatively straight forward, but more importantly, its robust and stable numericalsolution method minimizes tedious debugging saving time and computational resources.

2.1Upgrading from RiverFLO-2D v2009
If you own a RiverFLO-2D v2009license and are upgrading to RiverFLO-2D v3, you can follow the setup guide belowto install the new version. You can have both versions installed in the same computer and they will not interfere with
each other. There is no need to have a new hardware key. RiverFLO-2D v3uses the same key that works with v2009.

2.5 Installing RiverFLO-2D v3 / Argus ONE Network Version
NOTE: You will need Administrator permissions to install the RiverFLO-2D v3.Also, in Windows 7 you may need tomodify the program installation permissions.
Using RiverFLO-2D v3and Argus ONE on a network configuration with floating licenses allows the programs to beinstalled on as many networked PCs as required and used simultaneously from any of those PCs. The number of
users which can run RiverFLO-2D v3and Argus ONE concurrently equals to the number of licenses your organizationhas purchased. As long as this number is not exceeded, more users can start RiverFLO-2D v3and Argus ONE and useit from their own PC.
This section explains:
1.
How to install the license manager on the "license server".
2.
How to install RiverFLO-2D v3 and Argus ONE on the work stations so that it will look for the license overthe network.
The floating license configuration uses the Aladdin NetHASP technology which is comprised of two main
components:
1. NetHASP key (network USB hardware key).
2. License Manager Server software (LM).
The License Manager Server allows the RiverFLO-2D v3and Argus ONE programs to connect and communicate withthe network key provided. The network key must be connected to a USB port of the same PC the License Manager
(LM) server will be run on. This PC should be on the same network to which the users of RiverFLO-2D v3 and ArgusONE are connected. Many network protocols are supported including TCP/IP, UDP, and NetBios.
Installing Argus ONE Network Manager2.5.1
NOTE: Skip steps 1-4 if you are upgrading f rom v2009 network version.
1.
Make sure you have Administrator privileges before commencing.
2.
Be sure to pick a computer that is not often rebooted, since every restart of the LM will terminate any open
licenses. On the RiverFLO-2D v3 installation CD, open the folder NetHASPUtils, where you will find thefollowing files and directories:
a.
LMsetup.exe: Installer of the License Manager Program.
b.
Monitor Install: A directory containing the installer for the Monitor program used to monitor the
number and location of users.
c. NetHASP.ini: Optional Configuration file for the workstations.
d. Readme.txt: a copy of this file (the one you are now reading).
3. Run the LMsetup.exe double clicking on the file to install the required drivers and the LM as a service.
4. Connect the Network Hardware Key (Red USB NetHASP Key) to the USB port of the PC you selected for
installing the LM Server on. (Again, be sure to pick a computer that is not often rebooted, since every
restart of the LM will terminate any open licenses).
5.
Double click the file "RiverFLO-2D_v3_Network_Setup.exe" on the RiverFLO-2D v3 CD.6.
Follow the installation instructions on your screen to install both Argus ONE and RiverFLO-2D v3.7.
Open the Argus ONE program.
8.
If Argus ONE does not find the network manager close the program and reopen it.
It is recommended to start exploring RiverFLO-2D v3 reading this Users Guide.All RiverFLO-2D v3 documentation isinstalled in the folder:
