Explanations

• A: ID of the storm-water overflow basin(must begin with 'B')
• B: Basin type (DLB - through-flow basin, FB - stromflow tank, RRB - rain water retention basin)
• C: main water-flow pipe flows into basin (main connection) (H) (e.g. ---->--[Basin]---->---) or via a parallel connection (N), main pipe does not lead to basin.
• D: Calculation type (1 - approximation, 2 - characteristic curve with a non linear-reservoir, 3 - characteristic curve iterated)

Calculation type 1: approximation

• E: basin volume
• F: throttle outflow
• G: clear water overflow outflow

Calculation type 2 and 3: characteristic curve with a non linear-reservoir (2) or iterated (3)

• H: water level in the basin
• I: throttle outflow
• J: clear water overflow outflow
• K: basin overflow outflow
• L: basin volume

General

• M: settling class of the basin (s - bad, m - average, g - good, h - high)

Steering

• N: Control function for a rule-based steering. For this option, analog to dam-regulation/steering, a function-file (*.FKT) and a control-file (*.KTR) must exist in which the steering- and control information is stored. Currently only steering of the throttle outflow is implemented, Klärüberlauf and basin overflow can not (yet) be varied.
• O: Steering time series: Enables the time dependent scaling of throttle outflow. So far this too is only implemented for throttle outflow. The ID of a defined time series in the *.EXT file is entered here. The values of this time series are used for scaling.
