Normal precipitation is just the average of the last 30 year decal period. The precipitation patterns in Kansas have a major influences on the both the landscape and associated land use in the state.
*Results are based only on the cooperative network (KGS and KDA-DWR) and do not include sub-regional networks from the KDA-DWR, KGS, or local GMDs water levels are provisional.

11. Velocity (ft/d) = Gradient

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

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