Aboveground stem biomass ?Comment:Variable is a constant determined by the class variable; Land Cover and derived from the linked Leaf, Stem, Root (LSR) model. |
Belowground stem biomass ?Comment:Variable is a constant determined by the class variable; Land Cover and derived from the linked Leaf, Stem, Root (LSR) model. |
Disturbance type (for example, harvest, fire, grazing) ?Comment:Four disturbance types can be modeled in VELMA: BurnDisturbanceModel, effects of fire; GrazeDisturbanceModel, effects of grazing; FertilizeLsrDisturbanceModel, effects of fertilizer applications; HarvestLsrDisturbanceModel, effects of biomass harvest. Each of these disturbance models specifies where and when a disturbance event will occur. The Burn, Graze and Harvest models have options for specifying how much of each plant tissue and detritus pool (leaves, stems, roots) will be removed and where it goes (offsite and/or to a specified onsite C and N pools). The Fertilize model has options for applying nitrogen as ammonium, nitrate, urea and/or manure. Requirements for implementing a disturbance model include (1) a grid ASCII map of your watershed and associated parameter specifications that determine where and when a disturbance will occur, and (2) parameter specifications that determine which plant biomass and detritus pools will be affected, and the fraction of each pool burned, grazed or harvested and its destination. The user will specify land cover IDs, and one or more loops, years, and Julian days, or ranges of the same to be used for the modeled disturbance. Starting biomass is provided by the VELMA LSR model. |

The Fertilize model has options for applying nitrogen as ammonium, nitrate, urea and/or manure. Requirements for implementing a disturbance model include (1) a grid ASCII map of your watershed and associated parameter specifications that determine where and when a disturbance will occur, and (2) parameter specifications that determine which plant biomass and detritus pools will be affected, and the fraction of each pool burned, grazed or harvested and its destination. The user will specify land cover IDs, and one or more loops, years, and Julian days, or ranges of the same to be used for the modeled disturbance. Starting biomass is provided by the VELMA LSR model. |
Fraction of aboveground stem biomass converted ?Comment:The fraction [0.0 - 1.0] of available above-ground stem biomass converted/harvested from biomass above-ground stem to above-ground stem detritus and/or removed from the simulation. Constant determined by the driving class variables. |
Fraction of belowground stem biomass converted ?Comment:The fraction [0.0 - 1.0] of available below-ground stem biomass converted/harvested from biomass below-ground stem to below-ground stem detritus and/or removed from the simulation. Constant determined by the driving class variables. |
Fraction of converted aboveground stem biomass removed off site ?Comment:The fraction [0.0 - 1.0] of converted/harvested above-ground stem biomass removed offsite, i.e., removed from the cell and the simulation. Constant determined by the driving class variables. |
Fraction of converted belowground stem biomass removed off site ?Comment:The fraction [0.0 - 1.0] of converted/harvested below-ground stem biomass removed offsite, i.e., removed from the cell and the simulation. Constant determined by the driving class variables. |
Fraction of converted leaf biomass removed off site ?Comment:The fraction [0.0 - 1.0] of converted/harvested leaf biomass removed offsite, i.e., removed from the cell and the simulation. Constant determined by the driving class variables. |
Fraction of converted root biomass removed off site ?Comment:The fraction [0.0 - 1.0] of converted/harvested root biomass removed offsite, i.e., removed from the cell and the simulation. Constant determined by driving class variables. |
Fraction of leaf biomass converted ?Comment:The fraction [0.0 - 1.0] of available leaf biomass converted/harvested from biomass leaf to leaf detritus and/or removed from the simulation. This is a constant determined by the driving class variables. |
Fraction of root biomass converted ?Comment:The fraction [0.0 - 1.0] of available root biomass converted/harvested from biomass root to root detritus and/or removed from the simulation. Constant determined by the driving class variables. |
Leaf biomass ?Comment:Variable is a constant determined by the class variable; Land Cover and derived from the linked Leaf, Stem, Root (LSR) model. |
Root biomass ?Comment:Variable is a constant determined by the class variable; Land Cover and derived from the linked Leaf, Stem, Root (LSR) model. |
