1
Darcy's law is used to compute flow and velocity of ground water.
Recharge defines capture zone near a pumping well.
Retardation caused by the adsorption of contaminants.
Brake through curve denotes amount of water entering a shallow well.
Drawdown refers to arrival of contaminants entering into well
