pywr.recorders.StorageDurationCurveRecorder

class pywr.recorders.StorageDurationCurveRecorder(model, AbstractStorage node, percentiles, **kwargs)

This recorder calculates a storage duration curve for each scenario.

Parameters

modelpywr.core.Model

nodepywr.core.AbstractStorage

The node to record

percentilesarray

The percentiles to use in the calculation of the flow duration curve. Values must be in the range 0-100.

agg_func: str, optional

function used for aggregating the FDC across percentiles. Numpy style functions that support an axis argument are supported.

sdc_agg_func: str, optional

optional different function for aggregating across scenarios.

__init__(*args, **kwargs)

Initialize self. See help(type(self)) for accurate signature.
