Fig. 1. Effect of transport and release parameters on simulated fecal coliform concentrations in effluent collected at 90 cm depth; values of the varied parameter are shown at corresponding curves. (a) Various D in cm²min^-1, R = 0.5, µ = 0.005 min^-1, = 0.005 min^-1; (b) D = 0.5 cm²min^-1, various R, µ = 0.005 min^-1, = 0.005 min^-1; (c) D = 0.5 cm²min^-1, R = 0.3, µ = 0.005 min^-1, various in min^-1; (d) D = 0.5 cm²min^-1, R = 0.3, various µ in min^-1, = 0.005 min^-1; pore water velocity v was 0.5 cm min^-1 in all simulations.
