Variable General Info
ScaledVolumeV1 (LULC) ?Comment:This variable is input for fish species richness and fish number, a submodel of the ecosystem health submodel. To estimate the number of fish in the current IDU adjacent to the main stem of the Willamette River, get the ScaledVolumeV1 corresponding to the LULC of the IDU. Substitute the value into the provided regression equation for Number of Fish (Nhat). |
