    Dear all,

    I got confused by equation above figure 6 “Runoff from the third soil layer with a stream” in HYPE Model Documentation in section Land routines:

    deltah = (soil(3)-wp(3)-fc(3))/ep(3) * soillayerthick(3) –
    (soillayerthick(3) - streamdepth

    The parameter in bold (in the formula above) seems to be changed to soildepth(3) (or soillayerdepth(3)) or am I wrong?

    Other question about the text: “If for example the stream drainage level (streamdepth) is in the third layer (figure 6) and the soil layer is not saturated, the runoff depends on the water level above the drainage pipe level and the following equation replaces the one above.”
    Seems that in this case there is about the groundwater runoff and not about the drainage pipe runoff? So it seems that the words “drainage pipe” should be replaced by drainage depth?

    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.
