|
1D Boundaries |
1d_bc_ |
Layer(s) defining the locations of 1D domain boundaries. Note: Any links to the 2D domain are automatically determined via the 2d_bc layer(s). |
3.17 |
|
1D Initial Water Levels |
1d_iwl_ |
Optional layer(s) defining the spatial variation in initial water levels at 1D nodes at the start of the model simulation. |
3.16 |
|
1D Domain Network |
1d_nwk_ |
Layer(s) that define the 1D or quasi 2D domain network of flowpaths (channels) and storage areas (nodes). |
3.12 |
|
1D Tabular Input |
1d_ta_ 1d_xs_ 1d_nz_ 1d_bg_ |
Optional layer(s) that provide links to tabular data (eg. a cross-section’s X-Z values). Tabular data includes cross-sections (XZ and processed forms); storage surface area versus height at nodes (NA tables); and loss versus height coefficients at a structure (BG tables). Although, different table links can occur within the same layer, some modellers prefer to separate them and use prefixes such as those suggested to the left. |
3.13.3 |
|
1D Water Level Lines for SMS Output |
1d_wll_ |
Lines of horizontal water level (as judged by the modeller). These lines are used to generate 3D surfaces or water level, velocity and other output of 1D domains. This allows the combined viewing and animation of 2D and 1D domains together. |
