Contaminant ?Comment:Class variable |
Contaminant concentration |
Soil moisture (layer 1,2,3,4) ?Comment:Computed as part of the VELMA hydro model. |
Soil organic carbon (layer 1,2,3,4) ?Comment:In VELMA, users specify initial humus (soil organic matter) values (g C/m2) according to soil survey or other data, for example, NRCS soil survey map data. VELMA then calculates initial foc values and subsequent daily changes in foc in response to environmental and management drivers. VELMA calculates foc per soil layer per grid cell per day. |
Water flow ?Comment:Derived as output from the VELMA hydro model. |
