Flow to or from polders and drained lakes go to 114 Polders and drained lakes consist of leaky aquifers, the leakage being controlled by the polder level in the top semi-permeable layer. It is assumed that only horizontal flow takes place in the aquifer and only vertical flow through the semi-permeable layer as a consequence of different polder levels and surface water levels.
