The following report Introduces a documentation scheme for flow
oriented ecosystem models and shows its application to a carbon-water
model developed within the coniferous biome. This documentation scheme
has remained operative through revision of this model and expansion of
It to include nutrient flows. This model and subsequent versions are
operative simulations on the CDC 6400 at the University of Washington
using SIMCOMP (Gustafson S Innis (1971)).and give reasonable output.
The purpose of this report is mainly to introduce the reader to
the documentation scheme which we have found so effective in maintaining
a running history of the modeling process for large scale models.
We hope that it will lead to the adoption of this or a similar documentation
scheme as a standard for ecological modeling
