imod.evaluate.quiver_line#
- imod.evaluate.quiver_line(frf, fff, flf, start, end)[source]#
Obtain the u and v components for quiver plots for a line cross section through a three-dimensional flux field. The u and v components are obtained by first projecting the threedimensional flux components onto the provided cross-section.
- Parameters:
frf (xarray.DataArray) – Three- (or higher) dimensional dataarray of flow component along the rows (FLOW RIGHT FACE).
fff (xarray.DataArray) – Three- (or higher) dimensional dataarray of flow component along the columns (FLOW FRONT FACE).
flf (xarray.DataArray) – Three- (or higher) dimensional dataarray of flow component along the layers (FLOW LOWER FACE).
start ((2, ) array_like) – A latitude-longitude pair designating the start point of the cross section.
end ((2, ) array_like) – A latitude-longitude pair designating the end point of the cross section.
- Returns:
u (xarray.DataArray) – The u component (x-component) of the flow projection on the cross-section between start and end coordinate, with new dimension “s” along the cross-section. The cellsizes along “s” are given in the “ds” coordinate.
v (xarray.DataArray) – The v component (y-component) of the flow projection on the cross-section between start and end coordinate, with new dimension “s” along the cross-section. The cellsizes along “s” are given in the “ds” coordinate.
Notes
Use imod.evaluate.flow_velocity() first to obtain groundwater velocities as input for this function. Velocity in x direction is, however, inverted and must be re-inverted before using as input here.
