class timflow.steady.inhomogeneity.LeakyBuildingPitMaq(model, xy, kaq=1.0, z=None, c=None, npor=0.3, topboundary='conf', hstar=None, order=3, ndeg=3, layers=None, res=np.inf)#

Bases: LeakyBuildingPit

Element to simulate a building pit with a leaky wall in ModelMaq.

Parameters:

  • model (Model object) – model to which the element is added

  • xy (array or list) – list or array of (x,y) pairs of coordinates of corners of the inhomogeneity polygonal boundary is automatically closed (so first point is not repeated)

  • kaq (float, array or list) – hydraulic conductivity of each aquifer from the top down if float, hydraulic conductivity is the same in all aquifers

  • c (float, array or list) – resistance of leaky layers from the top down if float, resistance is the same for all leaky layers if topboundary=’conf’: length is number of aquifers - 1 if topboundary=’semi’: length is number of aquifers

  • z (array or list) – elevation tops and bottoms of the aquifers from the top down leaky layers may have zero thickness if topboundary=’conf’: length is 2 * number of aquifers if topboundary=’semi’: length is 2 * number of aquifers + 1 as top of leaky layer on top of systems needs to be specified

  • topboundary (string, 'conf' or 'semi' (default is 'conf')) – indicating whether the top is confined (‘conf’) or semi-confined (‘semi’). For a building pit, the ‘conf’ option is generally more applicable.

  • hstar (float or None (default is None)) – head value above semi-confining top, only read if topboundary=’semi’

  • npor (float, array or list) – porosity of all aquifers and leaky layers from the top down if float, porosity is the same for all layers if topboundary=’conf’: length is 2 * number of aquifers - 1 if topboundary=’semi’: length is 2 * number of aquifers

  • order (int) – polynomial order of flux along each segment

  • ndeg (int) – number of points used between two segments to numerically integrate normal discharge

  • layers (list or np.array) – layers in which leaky wall is present.

  • res (float or np.array, optional) – resistance of leaky wall, if passed as an array must be either shape (n_segments,) or (n_segments, n_layers). Default is np.inf, which simulates an impermeable wall.
