Abstract: Various statistical models are proposed for estimating the quality of rock masses. These models are then employed to relate RQD with the av erage number of discontinuity or average intact lengths. It is observed that the ...

Abstract: A nonequilibrium formula in terms of the depression cone volume is used to predict the drawdown variations in a fully penetrating large diameter well discharging from a leaky aquifer. The derivation of the formula is based ...

Abstract: Type curve expressions are derived analytically for drawdowns around a fully penetrating well in vertically graded hydraulic conductivity aquifers. A linear increase in the hydraulic conductivity with depth is adopted in ...

Abstract: A set of type curves has been derived for aquifer test analysis in horizontally fractured rock environments by using the volumetric approach. The validity of this approach has been confirmed with the numerical as well as ...

Abstract: A comprehensive review of the validity of Darcy's law is presented with the emphasis on the necessity for a nonlinear flow law for Reynolds numbers especially greater than one. Subsequently, the nonequilibrium formula is ...

Abstract: Nonequilibrium analytical solutions are presented for fully penetrating wells by incorporating the concept of the existence of a non‐Darcy flow regime around the pumping well and a Darcian flow regime away from the well. ...

Abstract: Nonlinear flow‐type straight‐line expressions are derived on the basis of exponential flow law instead of the linear Darcy law. A procedure of hypothesis testing for the flow‐regime linearity is explained step‐by‐step. It ...
