=Introduction=

*Modification of the floodplain topography by the creation of a 3D TIN surface;

*Revising the land use;

==Define Elevations (Building a TIN) ==

We have provided the GIS layers necessary to modify the ground elevations to represent the proposed development. This part of the tutorial will demonstrate how a TIN is created from these GIS layers. We will also update the GIS defining the road crest level. Follow the instructions below for your preferred GIS package.

 

==Define Surface Roughness ==

We have provided the GIS layers necessary to modify the land use areas that will change as part of the proposed development. This part of the tutorial will require populating the layer attributes to assign Manning’s n roughness values to each land use. Follow the instructions below for your preferred GIS package.

 

==Define Pipe Network ==

This part of the module creates the GIS layers that make up a pipe network. The pits of the pipe network will be linked to the 2D domain. We will also create the pit inlet database which links the GIS layers to depth-discharge curves. Follow the instructions below for your preferred GIS package.

 

==Define Boundary Conditions ==

This part of the module demonstrates how an inflow can be applied directly to the pits of the pipe network. A GIS layer of the inflow boundary has been provided. We will also modify the existing Boundary Conditions Database to include these new inflows. Follow the instructions below for your preferred GIS package.

 

=Modify Simulation Control Files and Set-up a TUFLOW Scenario=

 

==TGC File ==

 

=Run the Simulation=

In this tutorial we are using a batch file to run simulations. The command line in our batch file will be similar to that used in Module 6:<br>

{| class="wikitable "

If the TUFLOW simulation fails to start TUFLOW will output the error in a number of locations. Firstly, check the Console Window or the TUFLOW Log File (.tlf) (located in the '''TUFLOW\runs\log\''' folder with the name '''M07_5m_DEV_001.tlf'''). This file can be opened in a text editor and the error is generally located at the end of the file. You can however search for "Error" if you cannot see the error. In most cases there is also a spatial location for the error message (if the error reported in the log file is prefixed by XY:). To check the location of the geographic errors, open the '''M07_5m_DEV_001_messages.mif''' or '''M07_5m_DEV_001_messages_P.shp''' file in your GIS package.<br>

*[[TUFLOW_Message_2010 | ERROR 2010 - Material ID must be greater than 0 or less than 32767]]

*[[TUFLOW_Message_1118 | ERROR 1118 - Could not find pit inlet type ",a," in the pit inlet database]]

 

= Advanced - HPC Solver (Optional) =

 

TUFLOW HPC can run between 10 and 100 times faster than TUFLOW Classic using NVidia Graphics Processing Units (GPU)(depending on the model configuration and hardware performance).

==Results==

Using the methods described above in the <u>[[Tutorial_Module01_Archive#Viewing_Results | Viewing Results]]</u> section of Module 1.

* View the results in your preferred package.

Do the logs and results appear different to the TUFLOW Classic simulation?
