The forest hydrology model was developed as a means to quantify thermal and hydrological conditions and flows on a multi-year daily basis for forest sites and watersheds. The model uses daily precipitation (snowfall and rain, in cm) and temperature along with soil and catchment characteristics (latitude, altitude, slope, area, soil depth, etc…) to predict various aspects of pre- and post-harvest forest hydrology and nutrient cycling in a non-spatial trickle-down mode. Applications deal with a wide range of soil and climate conditions (arctic to tropical).

ForHyM is formulated in STELLA, a computer modeling software.  ForHyM receives its input (daily weather and soil / forest / watershed conditions) from a second interface (Excel) through dynamic linkage. This interface also contains Macros (i) to convert the continuous stream of daily weather into STELLA-ready format, (ii) to determine daily net radiation based on latitude, altitude, slope and aspect.

ForHyM will be available for public use, online, in the near future. If you have questions relating to the model or are interested in using ForHyM, please contact us. This will enable the center to keep in touch with those that use the model and provide assistance in the future. At the moment a blank excel interface is available to organize data inputs for future use with the online model.
