Video supplement: Factors determining the natural fresh-salt groundwater distribution in deltas

<p>This presents the 3D renderings of the groundwater salinity of all the trajectories in our global sensitivity analysis of a three-dimensional, variable-density groundwater model of a synthetic&nbsp;delta&nbsp;with complex paleo-hydrological boundary conditions</p> <p>In total there are 10 trajectories, each consisting of 24 simulations. So&nbsp;in total there are&nbsp;240 simulations.&nbsp;</p> <p>The videos show the development of the fresh-salt groundwater distribution over 45 ka for trajectories 1-10, viewed from the sea-side. Each panel is one step, at the top left it is which input is altered in which direction. A plus sign means an increase in the input, a minus sign a decrease. The blue-yellow-red color scale indicates salinity. The shaded areas the clay layers, the white color the location of the river boundaries and the black color the location of sea cells.&nbsp;Note that the vertical of each distribution with the following is stretched by a factor <span class="math-tex">\(4000/\log(\Delta z)\)</span>, since the system thickness varied logarithmically.</p> <p>&nbsp;</p>
