tuflow support 0 Report post Posted February 6, 2017 Q: When using a Global Rainfall boundary (via the "Global Rainfall BC == " command) do the spatially varying losses via the materials file apply, or only the Global Rainfall losses ("Global Rainfall Continuing Loss == " and "Global Rainfall Initial Loss == " commands)? A: When using a Global Rainfall BC the approach is more simplistic than the one than used for a 2d_rf layer. No memory is allocated for spatial losses and the global rainfall losses are the only ones that apply. These global losses are subtracted from the rainfall before the simulation and each cell gets the same rainfall applied. Therefore: The global rainfall losses commands only apply to global rainfall boundaries and not to 2d_rf polygons. The material losses do not apply to global rainfall boundaries. We will issue an updated 2016-03-AE manual in the coming weeks and this behaviour has been clarified. For future versions we will likely; add some warnings if either of the above configurations is specified, we will also look at supporting spatial losses for global rainfall, but will likely make a new command for doing so, to keep the existing behaviour.
