extent_contaminant

module wntr.metrics.water_security

extent_contaminant(quality, flowrate, wn, detection_limit=0)

Extent of contaminant in the pipes [27].

Parameters:

• quality (pandas DataFrame) – A pandas DataFrame containing node water quality (index = times, columns = node names).

• flowrate (pandas DataFrame) – A pandas DataFrame containing pipe flowrate (index = times, columns = pipe names).

• wn (wntr WaterNetworkModel) – Water network model. The water network model is needed to get pipe length, and pipe start and end node.

• detection_limit (float) – Contaminant detection limit.

Return type:

A pandas Series with extent of contamination (m)
