A postprocessor for uncertainty estimation of path lines in groundwater models
The code PPPath estimates the uncertainty of the location of path lines in a two-dimensional steady state confined or unconfined aquifer flow due to the uncertainty of the spatially variable unconditional hydraulic conductivity or transmissivity field. The method is based on the semi-analytical theory given in Stauffer et al. (2002, 2004). One application is the uncertainty estimation of the catchment of a pumping well by considering the boundary path lines starting at a stagnation point.
