The order of calculation of soil routines can for instance be found in the soilmodel_0 - subroutine in file soilmodel0.f90. There calculate_soil_runoff is called before calculate_tile_drainage (I'm looking at latest code not 4.10.7). A little later percolation is called and then your 3rd step is fulfilled.
Q1: runoffd=100mm so the ep(3)-pores will be emptied. Yes, unless a very large rain comes, the groundwater table will be much lower the next day, maybe even below the tile depth. No, this is not specially treated. Q2: Groundwater runoff is calculated and removed from soil water before runoffd is calculated. So the new water in ep-pores is used as limit for runoffd. This means that the ep(3)-pores will not be filled, and the deltah will never be above one. The additional calculations of adding to...
If the grey area in the figure is the soillayer with drainage pipe, then no, it is not correct. If trc is less than 1, then when the groundwater level is at the top of soil layer with drainage pipe the runoff is less than ep of that soillayer. When groundwater level is higher, runoff becomes higher up til it is equal to all water in ep-pores of that soil layer. That is the maximum.
trc gives the fraction of a volume that will be tile runoff every time step. This volume was chosen to be ep(3) since the drainage pipe is in this soil layer and this is the maximum volume available for runoff. But we wanted the tile runoff to depend on the groundwater level above the drainage pipe. The volume is therefore scaled with deltah/sthick(3); -deltah=0 gives no runoff, -deltah equal to the thickness of soillayer 3 gives that the whole ep-volume is involved and trc fraction is becoming runoff,...
Is there not any information of what is the problem in the log-file?
You are absolutely correct. I have changed the text on the wiki. Fortunately the code did not have the same misstake. Thank you for your help. Charlotta Pers
New HYPE version 5.0.3 released
When using the commandline to start HYPE you need to point to the model set-up (i.e. the location of the info.txt file) not just the HYPE.exe. E.g. F:\Directory1\HYPE\hype.exe D:\Directory2\model\
