The main factors affecting the well yield are the transmissivity and water yield coefficientof the aquifer as well as the permeability coefficient and thickness of the leaky layer.
含水层的导水系数、释水系数和弱透水层的渗透系数、厚度是影响井涌水量的两大重要因素。

Two factors are introduced to modify transmissivitycoefficientof a fracture or a fault, which represents the hydraulic effect of discrete fractures or faults.
