23.1 Groundwater Hydrology - II

23.1 Groundwater Hydrology - II#

Head and Gradients#

  • Determine gradient (magnitude and direction) from 3-wells

Storage#

The mechanisms of storage are:

  • draining and filling of the pore space

  • compression/decompression of the water, and

  • compression/decompression of the solids

Estimating storage from mapped water levels

Equation(s) of Motion#

  • Darcy’s Law and permeability

  • Measuring hydraulic conductivity
