Matrix flow is a relative slow and even movement of water and solutes through the soil while sampling all pore spaces, obeying the convective-dispersion theory which assumes that water follows an average flow path through soil (Figure 2). Group of eight-Canada, France, Germany, Italy, Japan, … Base Flow: Between storms and runoff events, stream flow is maintained by groundwater discharge known as base flow, as long as the water table remains above the stream bottom (Delleur, 1999).
