Pastas (TU Delft / Artesia) analyses groundwater head time series with transfer-function noise models: it decomposes observed heads into responses to rainfall, evaporation, pumping and other stresses, quantifying each driver's contribution without building a spatial model at all.
For questions like "how much of this decline is the new wellfield versus the drought," Pastas often answers in an afternoon what a calibrated MODFLOW model answers in a month. It has become the standard tool for head-series analysis in the Netherlands and is spreading with good reason.
