class PumpingTest(name, pumpingwell, pumpingrate, observations=None, aquiferdepth=1.0, aquiferradius=inf, description='Pumpingtest', timeframe=None)[source]

Bases: Test

Class for a pumping test.

This is a class for a pumping test on a field site. It has a name, a description, a timeframe and a pumpingwell string.

Parameters

name (str) – Name of the test.
pumpingwell (str) – Pumping well of the test.
pumpingrate (float or Variable) – Pumping rate of at the pumping well. If a float is given, it is assumed to be given in m^3/s.
observations (dict, optional) – Observations made within the pumping test. The dict-keys are the well names of the observation wells or the pumpingwell. Values need to be an instance of Observation Default: None
aquiferdepth (float or Variable, optional) – Aquifer depth at the field site. Can also be used to store the saturated thickness of the aquifer. If a float is given, it is assumed to be given in m. Default: 1.0
aquiferradius (float or Variable, optional) – Aquifer radius ot the field site. If a float is given, it is assumed to be given in m. Default: inf
description (str, optional) – Description of the test. Default: "Pumpingtest"
timeframe (str, optional) – Timeframe of the test. Default: None

Attributes

aquiferdepth: Variable: aquifer depth or saturated thickness.
aquiferradius: float: aquifer radius at the field site.
constant_rate: bool: state if this is a constant rate test.
depth: float: aquifer depth or saturated thickness.
observations: dict: observations made at the field site.
observationwells: tuple of str: all well names.
pumpingrate: float: pumping rate variable at the pumping well.
radius: float: aquifer radius at the field site.
rate: float: pumping rate at the pumping well.
testtype: str: String containing the test type.
wells: tuple of str: all well names.

Methods

`state`([wells])	Get the state of observation.

add_observations(obs)[source]

Add some specified observations.

Parameters: obs (dict, list, Observation) – Observations to be added.

add_steady_obs(well, observation, description='Steady State Drawdown observation')[source]

Add steady drawdown observations.

Parameters

well (str) – well where the observation is made.
observation (Variable) – Observation.
description (str, optional) – Description of the Variable. Default: "Steady observation"

add_transient_obs(well, time, observation, description='Transient Drawdown observation')[source]

Add transient drawdown observations.

Parameters

well (str) – well where the observation is made.
time (Variable) – Time points of observation.
observation (Variable) – Observation.
description (str, optional) – Description of the Variable. Default: "Drawdown observation"

correct_observations(aquiferdepth=None, wells=None, method='cooper_jacob')[source]

Correct observations with the selected method.

Parameters

aquiferdepth (float, optional) – Aquifer depth at the field site. Default: PumpingTest.depth
wells (list, optional) – List of wells, to check the observation state at. Default: all
method (:class: ‘str’, optional) – Method to correct the drawdown data. Default: ‘’cooper_jacob’’

Notes

This will be used by the Campaign class.

del_observations(obs)[source]

Delete some specified observations.

This will delete observations from the pumping test. You can give a list of observations or a single observation by name.

Parameters: obs (list of str or str) – Observations to be deleted.

diagnostic_plot(observation_well, **kwargs)[source]

Make a diagnostic plot.

Parameters: observation_well (str) – The observation well for the data to make the diagnostic plot.

Notes

This will be used by the Campaign class.

make_steady(time='latest')[source]

Convert the pumping test to a steady state test.

Parameters: time (str or float, optional) – Selected time point for steady state. If “latest”, the latest common time point is used. If None, it takes the last observation per well. If float, it will be interpolated. Default: “latest”

plot(wells, exclude=None, fig=None, ax=None, **kwargs)[source]

Generate a plot of the pumping test.

This will plot the pumping test on the given figure axes.

Parameters

ax (Axes) – Axes where the plot should be done.
wells (dict) – Dictionary containing the well classes sorted by name.
exclude (list, optional) – List of wells that should be excluded from the plot. Default: None

Notes

This will be used by the Campaign class.

save(path='', name=None)[source]

Save a pumping test to file.

This writes the variable to a csv file.

Parameters

path (str, optional) – Path where the variable should be saved. Default: ""
name (str, optional) – Name of the file. If None, the name will be generated by "Test_"+name. Default: None
