	*The coupled TUFLOW 1D engine requires the use of the double precision solver to achieve better stability in 1D with more significant numbers. This usually happens with 1D/2D models with ground elevation greater than 100m (TUFLOW 1D engine uses water level as the primary variable as TUFLOW Classic), carved 1D channels within the 2D domain where either the 1D channel itself or the boundary links between 1D and 2D domain can cause the mass error. *On rare occasions, models with higher elevations and small QT inflow would require double precision, because QT boundaries have hidden 1D node and as such are solved in the TUFLOW 1D engine.		*The coupled TUFLOW 1D engine requires the use of the double precision solver to achieve better stability in 1D with more significant numbers.

	***When the simulation time is long or the model has large Start Time value (more than 100000.0 hours), the around up issue can happen to the simulation time because the model timestep is typically in the order of 0.1~10 seconds. This might cause issues in reading and outputting boundary data.		***When the simulation time is long or the model has large Start Time value (more than 100000.0 hours), the around up issue can happen to the simulation time because the model timestep is typically in the order of 0.1~10 seconds.

	The single precision version of TUFLOW uses significantly less memory (RAM) and is about 20% faster for TUFLOW Classic and four times faster for HPC. Unless required otherwise, the single precision version of TUFLOW is recommended. A good step in the model development is to run the model with both the single and the double precision and if the results / mass balance are similar then the single precision version is sufficient.<br>		The single precision version of TUFLOW uses significantly less memory (RAM) and is about 20% faster for TUFLOW Classic and four times faster for HPC.

	TUFLOW Classic uses water level as the conserved variable in its implicit solution scheme. Due to this, some numerical precision can be lost under the above situations if single precision hardware is used. Loss of solution precision will be apparent by high mass balance error in the simulation log and result files. Single precision hardware can be used for all other situations without loss of accuracy or mass balance error issues. Running TUFLOW Classic (CPU hardware only) will on average increase simulation run times by approximately 20% when using double precision compared to single precision.

	Unlike TUFLOW Classic, single ~~precession~~ compute will be suitable for the majority of applications when using TUFLOW HPC with no loss of accuracy. The calculation method in TUFLOW HPC uses depth as its conserved variable in the explicit solution scheme. As a result the precision issues associated with applying a very small rainfall volume in a single timestep, or alternatively modelling at high elevation are not applicable in HPC. Note that a reduced wet/dry depth of 0.0002m (0.0007ft) is still recommended for direct rainfall models. When TUFLOW HPC is used on CPU hardware the differences in simulation speed between single and double precision range from 5% to 25% depending on the processor specifications. Running TUFLOW HPC on GPU hardware shows even greater simulation speed differences between single and double precision. The precision solver that is required for running TUFLOW on GPU hardware will determine the type of GPU card that is best suited for the compute. For any given generation/architecture of cards, the “gaming” cards such as the GTX GeForce and RTX provide excellent single precision performance – typically comparable to that of the “scientific” cards such as the Tesla series. If double precision is required, the scientific cards are substantially faster, though it’s also noting that they are also significantly more expensive. The Quadro series of GPU card currently tend to represent a middle ground between the “gaming” and “scientific” both in terms of double precision performance and cost.

 :::* Exclude buildings from the rainfall polygon: This removes the rainfall from the model that would otherwise fall on the buildings.

 :::* Exclude buildings from the rainfall polygon and represent the rainfall that would be falling on the building using <font color="blue"><tt>Read GIS SA RF</tt></font> inflow boundaries. To do this, digitise a 2d_sa_rf polygon for each building (with a buffer of one of more 2D cells) where the building footprint has been excluded from the direct rainfall region. The 2d_sa_rf input will convert the input rainfall hyetograph to flow, deposited initially on the lowest 2D cell, then for subsequent timesteps distributed over all wet cells, within the 2d_sa_rf regions (i.e. on the ground surrounding the building). Refer to TUFLOW <u>[[TUFLOW_Example_Models#Boundary_Condition_Options | Example model EG03_014.tcf]]</u> for a demonstration of this inflow boundary condition configuration.
 :::* Exclude buildings from the rainfall polygon and represent the rainfall that would fall on the building using <font color="blue"><tt>Read GIS SA RF PITS</tt></font> inflow boundaries. This approach is similar to the previous method, although instead of directing the inflow to the ground surrounding the building, it is directed into the sub-surface drainage (underground pipe) system. To implement this approach every 2d_sa_rf polygon must encompass at least one 1D pit. If multiple 1D pits are within a single 2d_sa_rf region, the flow from the polygon is split equally between the 1D pits.  The pits can be snapped to a 1D node, connected via the pit-search distance or via an x-connector, to allow captured by the pit to enter a 1D representation of the sub-surface drainage system. Refer to TUFLOW <u>[[TUFLOW_Example_Models#Multiple_Domain_Model_Design | Example model EG15_000.tcf]]</u> for a demonstration of this inflow boundary condition option.

= Direct Rainfall =
Please see [https://www.tuflow.com/library/webinars/#feb2021_direct_rainfall Direct Rainfall (Rain on Grid) Webinar]. 

= TUFLOW Executable =
* The single precision version of TUFLOW is recommended for direct rainfall models using HPC.
* The double precision version of TUFLOW is recommended for direct rainfall models using TUFLOW Classic.

= Rainfall Boundary Conditions=
The following links provide boundary condition guidance for applying direct rainfall:
* [[TUFLOW Rainfall Control File Examples]]
* [[TUFLOW NetCDF Rainfall Format]]

= Rainfall Losses and Soil Infiltration=
TUFLOW supports a range of rainfall loss and soil infiltration options. These are split into two broad categories, defined by their respective calculation methods:
* Rainfall Excess Losses
* Soil infiltration Losses
The fundamental difference in calculation approach is described in the below Common Questions Answered (FAQ) section.

Rainfall Excess losses can be implement in a variety of ways, including
<ol>
<li> Loss values specified within the TCF Read Materials File command, linking to TGC Read GIS Mat inputs;
<li> Loss values specified within the GIS layers associated with the TBC Read GIS SA RF command; or
<li> Global Rainfall Initial Loss and Global Rainfall Continuing Loss TBC commands.
</ol>

Similarly, a variety of soil infiltration options are supported. The available options include, Initial / Continuing Infiltration, the Horton Infiltration method and the Green-Ampt Infiltration method. The following link provides further discussion on the Green-Ampt method.
* [[Green-Ampt Infiltration Parameters | Green-Ampt Infiltration Parameters]]

= Common Questions Answered (FAQ)=
== What is the difference between rainfall excess and soil infiltration? ==
'''Rainfall Excess Approach - Read Materials File and Read GIS SA RF continuing loss specification:'''
*This initial and continuing loss approach is a simplistic calculation method comparable to the loss methods included in traditional hydrology models (e.g. RORB, URBS, WBNM etc).
*The calculation approach is as follows:
<ol>
*The user defines the rainfall hyetograph (time vs depth (mm)) boundary condition inputs.
*The rainfall value is reduced by the loss value (i.e. rainfall excess) before the boundary condition input is applied to the 2D cells.
*The GIS SA RF takes the rainfall excess (units = m) and multiples the value by the Area attribute (units = m2) in the GIS object to convert rainfall depth to a volume (m3).
*TUFLOW applies the calculated rainfall excess flow to the lowest cell in each GIS polygon during the first timestep that wetting occurs. Every timestep thereafter the inflow is distributed over the wet cells within the polygon.
</ol>
'''Soil Infiltration Approach - TUFLOW Soils File (.tsoilf):'''
*This approach is a more realistic representation of the actual physics associated with water infiltration into the soil.
*The calculation approach is as follows:
<ol>
*The user defines the rainfall hyetograph (time vs depth (mm)) boundary condition inputs.
*The total rainfall value is applied directly to every 2D cell within the 2d_rf polygon.
*When a 2D cell is wet the soil infiltration function subtracts the appropriate loss volume of water from it. Computationally this is referred to as a “Sink” term.
</ol>

== What is the best approach for modelling buildings in rain on grid model? ==
There are numerous different industry standard ways to represent buildings in a direct rainfall model. [https://downloads.tuflow.com/_archive/Australian_Rainfall_Runoff_Project_15_Subproject_report_buildings_final.pdf Australian Rainfall and Runoff Guideline, Project 15 (Representation of Buildings in 2D Numerical Flood Models] discusses some of the available options. Common TUFLOW modelling approaches are summarised below:
# Using depth-varying Manning's ''n'' over the area of the building footprint, with the application of a lower value (''n'' = 0.02) at shallow depths (d < 0.03m) and a higher value (''n'' > 0.3) at a more significant depths (d > 0.1m):
#* This is a very common and easy to implement option. The low Manning's ''n'' value aims to mimic the quick runoff response associated with drainage from the roof. The higher Manning's ''n'' value aims to represent the losses associated with deeper floodwater impacting the side of the building.
# Raise the building footprint elevation using TUFLOW's topographic update features (e.g. <tt>Read GIS Z Shape</tt>):
#* Raising the model topography creates an obstruction to flow. It prevents floodwater from passing through buildings (as is the case with the Manning's ''n'' approach)
#* The application of rainfall on top of the building can however produce some undesirable results that require further consideration. Those being, water falling from the building roof to the ground can require a reduced model timestep to maintain model stability which can slow the simulation speed. Also, depending on the Map Cutoff Depth assumptions, water may be present in the results on the building rooftops. This may not be desired for mapping purposes. There are a variety of options available to resolve these issues:
:::* Retain the model design described above, with subsequent post-processing of the mapped results before reporting. Either, delete the model result where there is overlap with the building footprint, or overlay the building footprint polygon objects over/above the result dataset in the GIS Map Layout (hiding the flood model result within the building footprints).
:::* Exclude buildings from the rainfall polygon: This removes the rainfall from the model that would otherwise fall on the buildings. This approach will under-estimate the amount of rainfall entering the model. If the collective building footprint area is negligible in comparison to the entire model, this approach may be acceptable.
:::* Exclude buildings from the rainfall polygon and represent the rainfall that would be falling on the building using <tt>Read GIS SA RF</tt> inflow boundaries. To do this, digitise a 2d_sa_rf polygon for each building (with a buffer of one of more 2D cells) where the building footprint has been excluded from the direct rainfall region. The 2d_sa_rf input will convert the input rainfall hyetograph to flow, deposited initially on the lowest 2D cell, then for subsequent timesteps distributed over all wet cells, within the 2d_sa_rf regions (i.e. on the ground surrounding the building). Refer to TUFLOW [[TUFLOW_Example_Models#Boundary_Condition_Options | Example model EG03_014.tcf]] for a demonstration of this inflow boundary condition configuration.
:::* Exclude buildings from the rainfall polygon and represent the rainfall that would fall on the building using <tt>Read GIS SA RF PITS</tt> inflow boundaries. This approach is similar to the previous method, although instead of directing the inflow to the ground surrounding the building, it is directed into the sub-surface drainage (underground pipe) system. To implement this approach every 2d_sa_rf polygon must encompass at least one 1D pit. If multiple 1D pits are within a single 2d_sa_rf region, the flow from the polygon is split equally between the 1D pits. The pits can be snapped to a 1D node, connected via the pit-search distance or via an x-connector, to allow captured by the pit to enter a 1D representation of the sub-surface drainage system. Refer to TUFLOW [[TUFLOW_Example_Models#Multiple_Domain_Model_Design | Example model EG15_000.tcf]] for a demonstration of this inflow boundary condition option.

== What is the recommended cell wet/dry depth for direct rainfall models? ==
For models with SGS turned off, a reduced cell wet/dry depth of 0.0002m (0.0007ft) is recommended due to the substantial amount of shallow sheet flow. 
If SGS is turned on, a reduced cell wet/dry depth is not necessary because the cell wet/dry calculation conducted on the SGS storage curve captures a greater change in depth. In the case, the default of 0.002m (0.007ft) may be sufficient; however, it should be reviewed and selected according to the magnitude of flooding depths.

QGIS is used to view the head loss across the 2D bridge with the TUFLOW Viewer. For viewing of the 2D map results, see [[Tutorial_M01_Results_QGIS | Module 1]]. 
 

= Method =
Plot head loss across the 2D bridge: 
<ol>
<li>Open the TUFLOW viewer.
<li>Select File > Load Results. Navigate to the '''M04_5m_001.tcf''' in the '''Module_04\TUFLOW\runs''' folder and open it.
<li>Use the Plot Cross Section tool to see head loss across the 2d_lfcsh: 
 
{{Video|name=Animation_M04_Results_01f.mp4|width=1270}} 
 
</ol>
Review structure group outputs: 
<ol>
<li>Plot the structure flow and the upstream and downstream water levels: 
 
{{Video|name=Animation_M04_Results_02e.mp4|width=1270}} 
 
<li>Navigate to '''Module_04\TUFLOW\results\plot\csv''' and open '''M04_5m_001_SHmx.csv'''. It contains a summary of each structure when the upstream water level reaches its maximum. The output columns include:
:*Flow, area and average velocity for below and above deck.
:*Total flow, area and average velocity for the whole structure.
:*Upstream and downstream water levels and the head drop across the structure (i.e. upstream minus downstream water level).
:*The time this data was recorded (i.e. the time the upstream water level peaked). 
The structure group output associates the 2d_po points and line with the same Label 'Bridge': 
 
[[File:M04_Results_03b.png]]
 
 
</ol>

= Conclusion =
:*The plot cross-section tool was used to view the head loss across the layered flow constriction.
:*A plot was made showing structure flow and the upstream and downstream water levels at layered flow constriction.
:*The _SHmx csv file was inspected showing a summary of the structure when the upstream water level reached its maximum.
:*For further functionality, see [[TUFLOW_Viewer | TUFLOW Viewer]].
