# Tabular Node Inflow

This feature allows users to establish a time-variable inflow for the drain analysis by transforming the **Inflow Hydrograph into a simple table** that lists Time against Flow values.

This input is suitable for **the Drain Analysis Mode**, where the software carries out routing for the drainage system. By defining the time-variable inflow, the software is able to produce a corresponding time-variable output, providing a detailed analysis of the flow’s behavior within the network.
