Edelman#

class Edelman(cutoff=0.999, **kwargs)[source]#

The function of Edelman, describing the propagation of an instantaneous water level change into an adjacent half-infinite aquifer.

Parameters:

up (bool or None, optional) – indicates whether a positive stress will cause the head to go up (True, default) or down (False), if None the head can go both ways.
gain_scale_factor (float, optional) – the scale factor is used to set the initial value and the bounds of the gain parameter, computed as 1 / gain_scale_factor.
cutoff (float, optional) – proportion after which the step function is cut off.

Notes

The Edelman function is explained in Edelman [1947].

The impulse response function for this class can be viewed on the Documentation website or using latexify by running the following code in a Jupyter notebook environment:

ps.Edelman.impulse

Methods#

`__init__`
`block`	Method to return the block function.
`gain`
`get_init_parameters`	Get initial parameters and bounds.
`get_t`	Internal method to determine the times at which to evaluate the step response, from t=0.
`get_tmax`	Method to get the response time for a certain cutoff.
`impulse`	Method to return the impulse response function.
`step`	Method to return the step function.
`to_dict`	Method to export the response function to a dictionary.
`update_rfunc_settings`	Internal method to set the settings of the response function.
