population_impacted

module wntr.metrics.misc

population_impacted(pop, arg1, operation=None, arg2=None)

Computes population impacted using comparison operators. For example, this can be used to find the population impacted when demand < 90% expected.

Parameters:

• pop (pd.Series (index = node names)) – A pandas Series that contains population per node

• arg1 (pd.DataFrame (columns = node names) or pd.Series (index = node names)) – Argument 1

• operation (numpy.ufunc) – Numpy universal comparison function, options = np.greater, np.greater_equal, np.less, np.less_equal, np.equal, np.not_equal

• arg2 (same size and type as arg1, or a scalar) – Argument 2

Return type:

A pandas Series that contains population impacted per node
