| TUFLOW supports 2D domains, 1D cross-section based domains, and 1D pipe network domains. Multiple domains of each type can be used within the same TUFLOW simulation. To use Multiple 2D domains in TUFLOW, you must purchase the add-on module.

| == Types of Domains ==
| |
| === 2D Domains ===
| |
| Two-dimensional domains are Cartesian grid (rectilinear) and include elevation data.

| === 1D Cross-section Domains ===
| |
| Cross-section based domains include channel and cross-section definitions.

| === 1D Pipe Network Domains ===
| |
| Pipe network domains can be used to model such things as culverts and storm sewers.

| ===1D to 2D Domains===

| A very powerful and useful feature in TUFLOW is the ability to combine a 1D cross-section domain and a 2D domain. This method can be used to embed a 2D domain between two 1D domains, embedding pipe networks, or to model the channel in 1D and floodplain in 2D. See [[SMS:TUFLOW Combining 1D and 2D Domains|Combining 1D and 2D Domains]].

| ===2D Domain to 2D Domain===
| |
| One of the disadvantages to TUFLOW is that it uses a fixed grid rather than a mesh which can transition very well from large to small cells. This can be overcome somewhat by using 1D and 2D domains. TUFLOW also supports using multiple 2D domains of different resolutions. The SMS interface makes it easy to setup using [[SMS:TUFLOW Linking 2D Domains|multiple 2D domains]].
