Documentation for a combined carbon-water flow stand level coniferous forest model

Creator:

Swartzman, G. L. (Gordon L.), Sollins, P., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

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...

Conifer : a model of carbon and water flow through a coniferous forest : revised documentation

Creator:

Sollins, P., Brown, Alfred T., Swartzman, G. L. (Gordon L.), and U.S. International Biological Program. Coniferous Forest Biome

Abstract:

CONIFER simulates water, carbon, and energy dynamics of a coniferous forest. The model consists of 29 nonlinear difference equations. Measured driving variables include air temperature, dew point temperature, precipitation, solar radiation, and wind speed. Water and energy variables are updated daily; carbon variables are updated weekly. This report contains a...

Models relating to terrestrial mineral cycling : progress report

Creator:

Strand, Mary Ann Sall, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

Although no formal project in mineral cycling was defined for 1972, three modeling efforts were begun: calcium cycling at Cedar River, litter decomposition, and miombo ecosystem. The calcium cycling model is a simple compartment model and was developed as a practice exercise. It demonstrates the inadequacy of linear-donor control formulation...

Stand structure simulation based on individual tree units

Creator:

Farnum, Peter, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

A model is developed to simulate basal area growth and mortality for forest stands using individual trees as the basic units. Yearly diameter increment, probability of death, and height-diameter relationship are computed from a competition measure which is based on crown overlap. This model is used to simulate the growth...

A conceptual model of soil mass movement, surface soil erosion, and stream channel erosion processes

Creator:

Swanson, Frederick J. (Frederick John), 1943-, Swanston, Douglas N., Dyrness, C. T., Cromack, Kermit, Fredriksen, R. L., Moore, Duane G., Glenn, Leslie Fred, 1944-, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

The conceptual framework of an erosion model has been designed to link processes of mass wasting, surface erosion, and channel storage and transport. A program to stimulate mass wasting will be based on a variation of the factor of safety approach which balances forces tending to drive mass movement against...

Trophic relation model based on density dependent processes

Creator:

Warren, Charles E., 1926-, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

"We have developed graphical and logical models for explaining the production of a consumer on the basis of the capacity of an ecosystem to produce that consumer (the productivity of the system for that consumer), on the basis of the biomass of the consumer, and on the basis of the...

Report of the aquatic modeling group : round one

Creator:

McIntire, C. David, Hall, James D., Higley, Duane Lee, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

The aquatic modeling group, consisting of Davis, Donaldson, Hall, Higley, Lyford, McIntire, Mullooly, Overton, Strand, Waring, and Warren, met in four 2-hour sessions from July 7 to July 26. The charge to the group was: 1. Define an appropriate internal structure for the aquatic subsystem; 2. Define significant couplings between...
