Conduit-Infiltration/Inflow and Seepage

Conduit-Infiltration/Inflow and Seepage Attributes

Attribute	Description
Infiltration Load Type	Lets you select the type of infiltration load associated with the selected conduit. You can select Link Length, Pipe Rise-Length, Pipe Surface Area, Count Based, Hydrograph, Pattern Load, or None.
Flow (Additional Infiltration)	Lets you enter any nominal amount of additional infiltration flow at the selected conduit. This additional amount is combined with any calculation local pipe infiltration setup with the choice of Infiltration Load Type. Note: With the GVF solvers, the resulting Additional Infiltration subtotals are reported along with Total Infiltration results as they accumulate in collection systems.
Infiltration Loading Unit	Lets you select the unit of measure for the infiltration load. To use this field, you must set the Infiltration Load Type to Link Length, Pipe Rise-Length, or Pipe Surface Area.
Infiltration Rate per Loading Unit	The infiltration rate per load for the selected conduit. To use this field, you must set the Infiltration Load Type to Link Length, Pipe Rise-Length, Pipe Surface Area, or Count Based.
Infiltration Unit Count	The infiltration unit count for the selected conduit. To use this field, you must set the Infiltration Load Type to Count Based.
Hydrograph Curve	Lets you define the infiltration load for the selected conduit as a hydrograph. Click the Ellipsis (…) button in this field to display the Hydrograph Curve dialog box, where you can define the Time vs. Flow data points that make up the hydrograph curve. To use this field, you must also set the Infiltration Load Type to Hydrograph. During a Steady-State solve, infiltration defined as time varying is ignored.
Infiltration Pattern	Lets you define the infiltration load as a pattern. You can select Fixed (the default value), an existing pattern, or Edit Pattern . When you select Edit Pattern, the Patterns dialog box appears. To use this field, you must set the choice of Infiltration Load Type to be Pattern Load. During a Steady-State solve, infiltration defined as time varying is ignored.
Flow (Infiltration Base)	The base infiltration flow for the selected conduit. To use this field, you must set the Infiltration Loading Type to Pattern Load.
