Beschreibungen/Notizen

• New equations are derived for the drawdown in a water-bearing fissured rock formation, consisting of a set of horizontal low-permeability porous blocks separated by highly permeable fissures. Porous blocks and fissures are assumed to be compressible. The depth of the fissure is small compared with that of the block. The abstraction well, lined along the block is pumped at a constant rate. The discharge per unit length of the unlined part in the fissure is constant, and the radius of the well is vanishingly small. Type curves for the drawdown in the fissure and the porous block are computed and plotted for some selected parameters involved. Procedure for determining the fissured aquifer parameter constants is outlined.
