Rate of Seepage (Q_{seepage})  Q_{seepage} = (Q t – ((π D^{2}/4) × d))/t  D = diameter of the well (m). d = depth of water column (m). Q = pumping rate (m^{3}/hour). t = time required for emptying the well (hour).  Raghunath (2006)  10.95 m^{3}/hour 
Specific Yield (S_{y})  S_{y} = (2.303/T) log_{10} s1/s2  s1/s2 = desidual drawdown ratio T = Time required for water level rising (hour).  Raghunath (2006)  8.546 hr^{−}^{1} 
Specific Capacity (S_{c})  Sc = S_{y} × A  S_{y} = Specific yield of the stream deposits. A = Area of the dug well section  Raghunath (2006)  90.624 m^{2} day^{1} 
Safe Yield (Qy)  Q_{y} = S_{y} A H  Q_{y} = safe yield of the well (m^{3}/s). A = area of cross section of the well (m^{2}). H = Safe working depression head (m). S_{y} = Specific yield of the soil.  Raghunath (2006)  176.694 m^{3}/day 
Transmissibility (T)  T = S_{c} × 1.2  T = Transmissibility (m^{2}/d). S_{c} = Specific Capacity  Raghunath (2006)  108.749 m^{2}/day 
Hydraulic Conductivity (K)  K= T/H  T = Transmissibility (m^{2}/d). H = Saturated thickness (m)  Raghunath (2006)  51.79 m/day 
Yield of Alluvial Bed (Q_{G})  Q_{G} = K A dh/dl  A = Cross sectional area (m^{2}) K= Hydraulic conductivity (m/day) dh/dl= Hydraulic gradient  Darcy’s Law  308.876 m^{3}/day 
Packer Test  T = Q ln(R/r_{b})/2π P_{i} K_{p} = T/L  T = transmissivity (m^{2}/day). Q = injection rate (m^{3}/day) and it was Zero. R = radius of influence (m). r_{b} = radius of borehole (m). P_{i} = net injection pressure (m). T = Transmissivity (m^{2}/day). L = Length of test zone and equal to 3 m.  Brassington (2007)  0
