Look for three torches sitting in the water, not far from land. Examine the middle of these torches to earn an Ability Point.Dig stairs down to the aquifer. Channel out a 5×5 ring down to the aquifer touching the stairs so your dwarves can use them to get back up. Leave a single tile at the surface connecting the center plug to the outide. This side-view illustration from the DF wiki showcases the procedure quite well.In some specific situations (like the flow inside aquifers) the anisotropy of the porous medium enhances the convective mixing and favours storage of carbon dioxide inside the aquifer . Anisotropy may enhance the dispersion and diffusion significantly inside porous materials [7,8].There are several popular aquifer models: van Everdingen-Hurst (VEH) model [1] Carter-Tracy model [2] Fetkovich model [3] Schilthuis model [4] Small- or pot-aquifer model [5] The first three models are unsteady-state models and are the most realistic. They attempt to simulate the complex pressure changes that gradually occur within the aquifer ...
