class timflow.steady.linesink.DitchString(model, xy=None, Qls=1, res=0, wh=1, order=0, layers=0, dely=0, label=None)#

Bases: RiverString

String of Ditches with specified discharge and uniform unknown head.

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 end-points of line-sinks in string

  • Qls (scalar) – total discharge of the string

  • res (scalar (default is 0)) – resistance of line-sinks in string

  • wh (float or str) –

    distance over which water enters line-sink.

    • if ‘H’: (default) distance is equal to the thickness of the aquifer (when flow comes mainly from one side)

    • if ‘2H’: distance is twice the thickness of the aquifer layer (when flow comes from both sides)

    • if scalar: the width of the stream that partially penetrates the aquifer

  • order (int (default is 0)) – polynomial order or inflow along each line-sink in string

  • layers (scalar, list or array) – layer(s) in which element is placed if scalar: element is placed in this layer if list or array: element is placed in all these layers

  • dely (float (default is 0)) – distance between control points and line

  • label (str or None) – label of element
