What is the recommended method for representing a railway ballast area in TUFLOW?
A railway ballast area in TUFLOW can be represented as a soil layer (specific soil ID) with high infiltration, suitable porosity, and high hydraulic conductivity in both horizontal and vertical directions.
A global soil thickness value can define the depth of this layer relative to the surface elevation. Similarly, a global soil base elevation value beneath the railway ballast area can set the absolute elevation of its bottom. Both parameters can also be varied spatially with GIS and/or grid layers.
