Thanks for clarifying this. Can I suggest that you add this information as a single sentence in the wiki to avoid potential confused. Maybe right before you write this sentence: The actual infiltration is calculated by subtracting the macropore flow and surface runoff from the sum of snow melt and rain. you could have a sentence like The water that becomes infoverflow is instantaneously transferred to the local river without any storage and delay.

May I humbly suggest that you add some short additional text to the wiki to avoid potential confusion in the future: http://hype.smhi.net/wiki/doku.php?id=start:hype_model_description:hype_routing#simple_outlet_lake_or_dam_olake Right now, the paragraph reads: gratk, gratp and grata are general parameters that apply to all lakes in the model application. ratcorr is parameter region dependent model parameter for adjusting gratk to different regions. The upstream area (uparea, km^2) is included in...

Good to know, thanks! Just to be clear: The unit of the outflow is always m3/s regardless of whether the user runs HYPE with daily or hourly time steps? Presumably the code then integrates the outflow rate in cubic meter per second up to the model time step length? :)

Thank you Lotta! I am trying out different ways of calibrating one or more of these parameters. But I am struggling with trying to come up with some reasonable parameter ranges to search within I talked to one of your SMHI colleagues and he provided a parameter set (which I think might come from S-HYPE, but I am not entirely sure about this...): gratk = 0.24 grata = 0.45 gratp = 2 I am wondering about the units of the different elements in the rating curve equation: wlm_lakedepth = meters uparea...

Hi, I have read the wiki page on simple outlet lakes and dams: http://hype.smhi.net/wiki/doku.php?id=start:hype_model_description:hype_routing#simple_outlet_lake_or_dam_olake The wiki describes several equations for the outflow from olakes depending on the value of grata (let's forget the option for regional correction factors corr here), Here is the equation for grata > 0: outflow = gratk * (uparea^grata ) * (wlm_lakedepth^gratp) For the last equation, it is unclear to me what exactly uparea refers...

Hi, I have read the wiki page on the land routines and I am unsure about how surface runoff is handled when using the default macropore/surface runoff formulation (governed by mactrinf and mactrsm). From the wiki, I understand that: infoverflow (surface runoff to nearest stream) occurs when the thresholds mactrinf and mactrsm are exceeded. Surface runoff can also occur from saturated conditions / upwelling to the surface. My questions are about whether these two runoff contributions are treated the...

Hi Lotta, I have the same problem as Magnus, except I'm running HYPE version 5.18.0. Have you made any progress with this bug? Cheers, Jonas
