Description

Water transport in the crushed rock in the central area before saturation is mainly governed by the inflow rate and inflow distribution in the rock. Since the expected hydraulic conductivity of the crushed rock is rather high, and since there will be an open slot at the roof, the resistance to water inflow into the filling material will be very low.
