pywr.parameters.UniformDrawdownProfileParameter

class pywr.parameters.UniformDrawdownProfileParameter(model, reset_day=1, reset_month=1, **kwargs)

Parameter which provides a uniformly reducing value from one to zero.

This parameter is intended to be used with an AnnualVirtualStorage node to provide a profile that represents perfect average utilisation of the annual volume. It returns a value of 1 on the reset day, and subsequently reduces by 1/366 every day afterward.

Parameters

reset_day: int

The day of the month (1-31) to reset the volume to the initial value.

reset_month: int

The month of the year (1-12) to reset the volume to the initial value.
