PRB Flow Characteristics
A potential problem with reactive barriers is the development of preferential flow pathways within the reactive material. Simulations suggest ... between the dissolved contaminants and the reactive material, potentially leading to a reduction in the effectiveness and lifespan of the reactive wall (Benner, 1997). The detection of ...
