3.18Presenting 1D Domains in 2D Output (1d_wll)
Output from 1D domain(s) can be combined with the 2D map output viewed using SMS or a GIS. This allows easier viewing of results and the ability to animate the 1D results in combination with the 2D results.
1d_wll GIS layer(s) are used to define and control the 1D map output. The layer(s) contain lines (called WLLs or Water Level Lines) that cross 1D channels and/or nodes. A WLL is essentially a line of horizontal water level, and should be digitised on this basis (ie. perpendicular to the flow direction).
As of Build 2003-10-AE, two methods are available, although both methods have been modified and improved up until Build 2004-06-AB. Use WLL Approach to set the preferred method. The two methods are described below. Method B allows more advanced and accurate mapping of 1D results in map formats.
