M0 PRECSDEVEVAP FWELL NAMEM0 WELL- The zeroth moment or Gain of the response of the groundwater level toprecipitation- The standard deviation of the parameter in the previous column- Evaporation reduction factor, not to be confused with the crop factor usedin unsaturated zone hydrology- Name of a groundwater well that was used as explanatory series- The zeroth moment or Gain of the response of the groundwater level topumping from this well.Description of the parameters of different types of explanatory series:Prec,- The three parameters that are estimated and exported are parameters ofthe Pearson III distribution (see [Von Asmuth et al., 2006]).Evap - The only parameter that is estimated is an evaporation reduction factor [-].Except for this, the response equals that of precipitation (see also [VonAsmuth et al., 2006]).Well, River - For Well, these are the three overall parameters the well function ofHantush and for River, these are the three parameters of the polder functionof Bruggeman (see [Von Asmuth et al., 2006]).Impulse - This parameter gives the change of the groundwater level in meters. Forlinear_trend this is the change over the selected period, and for step_trendthe final, stationary change.BoxJen- For an explanation of the parameters of Box-Jenkins models see [Box andJenkins, 1970].Menyanthes Manual© KWR - 54 -
