"""
Convert wells to imod5 data, loaded with
:func:`imod.formats.prj.open_projectfile_data`, to a Well object. As
iMOD5 handles wells differently than iMOD Python normally does, some
data transformations are made, which are outlined further.
iMOD5 stores well information in IPF files and it supports two ways to
specify injection/extraction rates:
1. A timeseries of well rates, in an associated text file. We will
call these "associated wells" further in this text.
2. Constant rates in an IPF file, without an associated text file.
We will call these "unassociated wells" further in this text.
Depending on this, iMOD5 does different things, which we need to mimic
in this method.
*Associated wells*
Wells with timeseries in an associated textfile are processed as
follows:
- Wells are validated if the following requirements are met
* Associated well entries in projectfile are defined on either all
timestamps or just the first
* Multiplication and addition factors need to remain constant through time
* Same associated well cannot be assigned to multiple layers
- The dataframe of the first projectfile timestamp is selected
- Rate timeseries are resampled with a time weighted mean to the
simulation times.
- When simulation times fall outside well timeseries range, the last
rate is forward filled.
- Projectfile timestamps are not used. Even if assigned to a
"steady-state" timestamp, the resulting dataset still uses simulation
times.
*Unassociated wells*
Wells without associated textfiles are processed as follows:
- When a unassociated well disappears from the next time entry in the
projectfile, the well is deactivated by setting its rate to 0.0. This
is to prevent the well being activated again in case of any potential
forward filling at a later stage by
:meth:`imod.mf6.Modflow6Simulation.create_time_discretization`
- Wells assigned to a "steady-state" entry in the projectfile will have
no "time" dimension in the resulting dataset.
- Times beyond the year 2261 are out of bounds for pandas. In associated
timeseries these are ignored, instead the last stage is forward
filled.
.. note::
In case you are wondering why is this so complicated? There are two
main reasons:
- iMOD5 is inconsistent in how it treats timeseries for grid data,
compared to point data. Whereas grids are forward filled when
there is no entry specified for a time entry, unassociated wells
are deactivated. Associated wells, however, are forward filled.
- Normally there are two levels in which times are defined: The
simulation times, which are the requested times for the
simulation, and projectfile times, on which data is defined. With
associated ipfs, times are defined in three
levels: There are simulation times (in iMOD5 in the ini
file), there are projectfile times, and there are times
defined in the associated textfiles on which data is defined.

Parameters
----------
y: list of floats or np.array of floats
is the y location of the well.
x: list of floats or np.array of floats
is the x location of the well.
screen_top: list of floats or np.array of floats
is the top of the well screen.
screen_bottom: list of floats or np.array of floats
is the bottom of the well screen.
rate: list of floats or xr.DataArray
is the volumetric well rate. A positive value indicates well
(injection) and a negative value indicates discharge (extraction) (q).
If provided as DataArray, an ``"index"`` dimension is required and an
optional ``"time"`` dimension and coordinate specify transient input.
In the latter case, it is important that dimensions are in the order:
``("time", "index")``
concentration: array of floats (xr.DataArray, optional)
if this flow package is used in simulations also involving transport, then this array is used
as the concentration for inflow over this boundary.
concentration_boundary_type: ({"AUX", "AUXMIXED"}, optional)
if this flow package is used in simulations also involving transport, then this keyword specifies
how outflow over this boundary is computed.
id: list of Any, optional
assign an identifier code to each well. if not provided, one will be generated
Must be convertible to string, and unique entries.
minimum_k: float, optional
on creating point wells, no point wells will be placed in cells with a lower horizontal conductivity than this
minimum_thickness: float, optional
on creating point wells, no point wells will be placed in cells with a lower thickness than this
print_input: ({True, False}, optional)
keyword to indicate that the list of well information will be written to
the listing file immediately after it is read.
Default is False.
print_flows: ({True, False}, optional)
Indicates that the list of well flow rates will be printed to the
listing file for every stress period time step in which "BUDGET PRINT"
is specified in Output Control. If there is no Output Control option
and PRINT FLOWS is specified, then flow rates are printed for the last
time step of each stress period.
Default is False.
save_flows: ({True, False}, optional)
Indicates that well flow terms will be written to the file specified
with "BUDGET FILEOUT" in Output Control.
Default is False.
observations: [Not yet supported.]
Default is None.
validate: {True, False}
Flag to indicate whether the package should be validated upon
initialization. This raises a ValidationError if package input is
provided in the wrong manner. Defaults to True.
repeat_stress: Optional[xr.DataArray] of datetimes
Used to repeat data for e.g. repeating stress periods such as
seasonality without duplicating the values. The DataArray should have
dimensions ``("repeat", "repeat_items")``. The ``repeat_items``
dimension should have size 2: the first value is the "key", the second
value is the "value". For the "key" datetime, the data of the "value"
datetime will be used. Can also be set with a dictionary using the
``set_repeat_stress`` method.

"""
Agnostic WEL package, which accepts x, y and layers.
This package can be written to any provided model grid, given that it has
enough layers. Any number of WEL Packages can be specified for a single
groundwater flow model.
https://water.usgs.gov/water-resources/software/MODFLOW-6/mf6io_6.0.4.pdf#page=63
Parameters
----------
y: list of floats or np.array of floats
is the y location of the well.
x: list of floats or np.array of floats
is the x location of the well.
layer: list of ints or np.array of ints
is the layer of the well.
rate: list of floats or xr.DataArray
is the volumetric well rate. A positive value indicates well
(injection) and a negative value indicates discharge (extraction) (q).
If provided as DataArray, an ``"index"`` dimension is required and an
optional ``"time"`` dimension and coordinate specify transient input.
In the latter case, it is important that dimensions are in the order:
``("time", "index")``
concentration: array of floats (xr.DataArray, optional)
if this flow package is used in simulations also involving transport, then this array is used
as the concentration for inflow over this boundary.
concentration_boundary_type: ({"AUX", "AUXMIXED"}, optional)
if this flow package is used in simulations also involving transport, then this keyword specifies
how outflow over this boundary is computed.
id: list of Any, optional
assign an identifier code to each well. if not provided, one will be generated
Must be convertible to string, and unique entries.
minimum_k: float, optional
on creating point wells, no point wells will be placed in cells with a lower horizontal conductivity than this
minimum_thickness: float, optional
on creating point wells, no point wells will be placed in cells with a lower thickness than this
print_input: ({True, False}, optional)
keyword to indicate that the list of well information will be written to
the listing file immediately after it is read.
Default is False.
print_flows: ({True, False}, optional)
Indicates that the list of well flow rates will be printed to the
listing file for every stress period time step in which "BUDGET PRINT"
is specified in Output Control. If there is no Output Control option
and PRINT FLOWS is specified, then flow rates are printed for the last
time step of each stress period.
Default is False.
save_flows: ({True, False}, optional)
Indicates that well flow terms will be written to the file specified
with "BUDGET FILEOUT" in Output Control.
Default is False.
observations: [Not yet supported.]
Default is None.
validate: {True, False}
Flag to indicate whether the package should be validated upon
initialization. This raises a ValidationError if package input is
provided in the wrong manner. Defaults to True.
repeat_stress: Optional[xr.DataArray] of datetimes
Used to repeat data for e.g. repeating stress periods such as
seasonality without duplicating the values. The DataArray should have
dimensions ``("repeat", "repeat_items")``. The ``repeat_items``
dimension should have size 2: the first value is the "key", the second
value is the "value". For the "key" datetime, the data of the "value"
datetime will be used. Can also be set with a dictionary using the
``set_repeat_stress`` method.

WEL package for discretization by vertices (DISV) models. Any number of WEL
Packages can be specified for a single groundwater flow model.

.. warning::
This class is deprecated and will be deleted in a future release.
Consider changing your code to use the ``imod.mf6.Well`` package.
Parameters
----------
layer: list of int
Modellayer in which the well is located.
cell2d: list of int
Cell in which the well is located.
rate: float or list of floats
is the volumetric well rate. A positive value indicates well (injection)
and a negative value indicates discharge (extraction) (q).
concentration: array of floats (xr.DataArray, optional)
if this flow package is used in simulations also involving transport,
then this array is used as the concentration for inflow over this
boundary.
concentration_boundary_type: ({"AUX", "AUXMIXED"}, optional)
if this flow package is used in simulations also involving transport,
then this keyword specifies how outflow over this boundary is computed.
print_input: ({True, False}, optional)
keyword to indicate that the list of well information will be written to
the listing file immediately after it is read. Default is False.
print_flows: ({True, False}, optional)
Indicates that the list of well flow rates will be printed to the
listing file for every stress period time step in which "BUDGET PRINT"
is specified in Output Control. If there is no Output Control option and
PRINT FLOWS is specified, then flow rates are printed for the last time
step of each stress period. Default is False.
save_flows: ({True, False}, optional)
Indicates that well flow terms will be written to the file specified
with "BUDGET FILEOUT" in Output Control. Default is False.
observations: [Not yet supported.]
Default is None.
validate: {True, False}
Flag to indicate whether the package should be validated upon
initialization. This raises a ValidationError if package input is
provided in the wrong manner. Defaults to True.
