Calculation of the unsteady effect of reclamation drainage with in-depth consideration of the effect of the zone of aeration and infiltrations

Gidrodin. akust. 2018, 1(1):53-69




The analytical solution is obtained for a non-linear problem of a non-steady groundwater flow to systematic horizontal drain system in view of the impact of the aeration zone and infiltration. On its base the equation for calculation of a reliable drain spacing at given requirements to soil drainage is derived. The solution behavior is illustrated on several examples, the expedience of more exact description of water exchange between the saturated and unsaturated zones is demonstrated that makes it possible to increase the drain spacing.
