The Initial Buildup editor is used to edit the
Initial Buildup property of a Subcatchment. It specifies the amount of
pollutant buildup existing over the subcatchment at the start of the simulation.
| Field | Description |
| Pollutant Name | Initial buildup values (lb/ac) or (kg/ha). If no buildup value is supplied, it is assumed to be 0. If a non-zero value is supplied for the initial buildup of a pollutant, it will override any initial buildup computed from the Antecedent Dry Days parameter specified on the Dates tab of the Simulation Options page. |
| Curb Length | Total length of curbs in the subcatchment (any length units). Used only when pollutant buildup is normalized to curb length. |
