Hydrology trend rates in equivalent water thickness (EWT) superposed on surface topography. a From W1315 with \(1/\alpha = -\,0.15\,\upmu {\hbox {Gal/mm}}\). b From L2013. c From W1315 with \(1/\alpha = -\,0.165\,\upmu {\hbox {Gal/mm}}\). d From W1315 with \(1/\alpha = -\,0.177\,\upmu {\hbox {Gal/mm}}\). Note the colour scale refers to the surface topography and the black contours are for the EWT trend rates
