Simultaneous Transport Of Water And 3hoh In Water, H. D. Scott

Technical Reports

Dispersion of ³HOH was studied at flow velocities less than 14 cm/day in a Captina silt loam using the half-cell technique. Two directions of transport were studied: movement of ³HOH in the same direction as water, and movement of ³HOH in the opposite direction to that of water. Results indicated that the dispersion coefficients were velocity dependent for equilibration times ranging to 21 hours. As the average pore flow velocity increased, the length of time needed for the dispersion coefficients to become independent of the flow velocity increased. When considering transport of ³HOH in the same …
