Thomas County Index Well - Water Table Elevations

Velocity (ft/d) = Gradient

Velocity (ft/d) = Gradient * Hydraulic Conductivity (ft/d)

Velocity (ft/d) = Gradient Velocity (ft/d) = Gradient * Hydraulic Conductivity (ft/d) / Specific Yield

Velocity (ft/d) = Gradient Velocity (ft/d) = Gradient * Hydraulic Conductivity (ft/d) / Specific Yield 0.86 0.82 0.48 0.61 0.43 Average = 0.64 ft/d ≈ 234 ft/yr 22-23 years to go 1 mile.
