摘要: The impoundment of the Rudbar dam raised underground water level. On right bank, elevation table is monitored in exploratory boreholes. has remained below level reservoir. lower due to tunnels and galleries that behave as drains. Special analytic developments have been carried out analyze behavior during impoundment. peculiarity model it considers a draining tunnel an open aquifer with free table. Two new equations are obtained: one for inflow other drawdown. These used assess boreholes, calculate hydraulic conductivity rock mass from measured seepage conveyance tunnel, determine efficiency sealing back pressure on extrados drainage gallery. comparison calculated available information measurements packer tests DFN predictions will reveal importance scale effects uncertainties.
