Accurate prediction of solute transport processes in a fracture aquifer is an important task not only for proper management of the groundwater but also for pollution control.
A key issue of this task is how to accurately obtain the experimental data and to analyze the solute transport in fracture in subsurface hydrology, which would greatly help us to understand the releasing mechanism and transport of the solute in a fracture.
In this study, a fracture experiment is conducted in a laboratory based on previous studies.
The fracture used with a length of 60 cm and a width of 10 cm is sealed with glass glue to avoid leakage of tracer due to uneven fracture walls.
The sodium chloride (NaCl) solute is injected from the left of the fracture.
And an electrical conductivity monitoring system is installed on the right of the fracture.
Then breakthrough curves (BTCs) of solute transport are fitted using the classical advection-dispersion equation (ADE) and the truncation power-law function (TPL) model in the package of the continuous time random walk (CTRW).
The results show that the flow satisfies non-Darcian law in the experimental conditions, which can be better fitted using the Forchheimer equation and Izbash equation.
The solute transport presents non-Fickian phenomena and shows a long tailing.
The fitting results of the TPL model are far better than ADE in fitting the long tailing at three different flow velocities.
Furthermore, electrical conductivity monitoring method not only is effective but also has an advantage of no disturbance to water and concentration fields in a fracture.
