= SWMM inclusion in TUFLOW (2023-03-AD or newer)=
If you wish to model SWMM coupled dynamically to TUFLOW 2D, please refer to the <u>[[TUFLOW_SWMM_Tutorial_Introduction | TUFLOW SWMM Tutorials]]</u> and <u>[https://docs.tuflow.com/classic-hpc/release/2023-03-AE/SWMM-TUFLOW-1.html Chapter 4 of the 2023-03 Release Notes]</u>. Step by step model build examples are provided for the following topics:
* <u>[[TUFLOW SWMM Tutorial M01 | TUFLOW SWMM Module 1]]</u> - 1D SWMM Culverts
* <u>[[TUFLOW SWMM Tutorial M02 | TUFLOW SWMM Module 2]]</u> - 1D SWMM Pipe Network / 2D TUFLOW Direct Rainfall Hydrology
Line 20:
The SWMM_to_TUFLOW utility automates the conversion of SWMM 1D model geometry for culverts, pipes and open channels into a TUFLOW 1D (ESTRY) compatible GIS and tabular format.<br>
'' Note: TUFLOW 1D does not include an inbuilt hydrology engine. As such, SWMM hydrology and boundary condition information is not processed by this utility. If SWMM hydrology or boundary condition information is important for your model

* SWMM includes a larger range of inbuilt culvert geometry types than TUFLOW 1D. TUFLOW 1D primarily supports Circular (C) and Rectangular (R) as hardcoded culvert / pipe geometries. All others SWMM culvert types are converted to TUFLOW 1D Irregular (I) culverts, with an associated Height vs Width 1D cross-section to define the culvert geometry.
* SWMM includes a variety of inbuilt pipe network inlet geometries. This information is not processed by the utility. It is the modellers responsibility to manually create depth / flow relationship information for the pit inlet database if using TUFLOW 1D. If you wish to use the inbuilt SWMM pipe network inlet geometries directly, please use direct coupling of SWMM with TUFLOW. Refer to <u>[[TUFLOW_SWMM_Tutorial_Introduction | TUFLOW SWMM Tutorial Module 2 and 3]]</u>
