The objective of this study was to develop a novel methodology to use BTC of non-conservative tracers such as chloride and bromide as surrogates for the purpose of calculating pore-water velocity and corresponding pore-size spectrums in soils. Miscible displacement tests of Cl were conducted on repacked sand and undisturbed soil columns with 8.0 cm id and 13-30 cm length.  The resultant BTCs were divided into about 30 segments, and amount of mobile water (Q_mi) needed to transport the amount of tracer recovered at the exit of the column for corresponding segment was calculated as Q_mi = (DC_rixDP_rixP₀)xP_r(Cr=1.0), where DC_ri is the difference in dimensionless concentration, DP_ri is the difference in dimensionless pore volume, P₀ is the amount of water held in the column (simply pore volume of the column), and P_r(Cr=1.0) is dimensionless pore volume at C_r =1.0.  Pore water velocity (v_i) for segment i was calculated as v_i = (zl/t) where,  z is tourtuousity (-), l (L) is the length of the column and t (T) is time elapsed from traced effluent to start displacing non-traced effluent in the column. Mean radius of the pores within size class i was calculated, using calculated v_i with Poiseuille’s equation.  Number of the pores in each size-class i was calculated dividing volume of effluent discharging in unit time (Q_mi/(t_i+1-t_i), where t_i+1-t_i is the time length for which  Q_mi is recovered) by cross-sectional area of mean pore-size calculated for size class i. The predicted mean pore-water velocity (v_p) for saturated columns was calculated form geometric mean of pore-water velocity-values calculated for all the segments. Saturated mean pore-water velocity of the columns was measured, and measured (v_m) and predicted (v_p) pore-water velocity-values were converted to saturated hydraulic conductivity, multiplying v_m and v_p by saturated water content (L³ L^-3) of the columns.  Correlation analysis conducted between v_m and v_p resulted in a correlation coefficient of r= 0.90.
