6. One paragraph description of your model (e.g. abstract from report or
   paper);

The SOIL-modelis calculating combined heat and water fluxes in the
(one-dimensional) soil-snow-atmosphere system. The two basic 
assumptions for the soil are the Richards-equation (Richards, 1931) 
for water flow and Fourier's law for heat flow. Standard meteorological 
data are used as inputs, and the boundaries are determined by 
formulations of interception, drainage flow, percolation and 
geothermal heat flux. For the description of those parts of the 
model which are not focused by the present study it is
referred to Jansson (1996) or Johnsson & Jansson (1991).
