Your question is difficult to answer because many factors will affect ground water recharge:

  • Soil porosity, which will be affected by soil pore space volumes, soil cohesion (the distribution of clay & sand etc. within the soil matrix) and the presence of hydrophobic soil grains and minerals
  • Soil moisture content
  • Depth of the soil
  • The presence or absence of water impervious strata, such a clays
  • The presence or absence of ground fissures, faults or other discontinuities that can allow water to be channelled through them
  • The amount of rain that falls and surface evaporation rates
  • The depth of the ground water table
  • Drought affected soil may have soil grains that may need to be hydrated, by absorbing some water, prior to letting surplus water pass by them
