Resum
Parameters estimated from forced-gradient tracer tests are often used to simulate the transport of large contaminant plumes under natural gradients, yet the difference in the flow system and the plume size is important. Recent intermediate-scale experiments and numerical simulations in two dimensions have suggested that dispersivities from forced-gradient tracer tests involving a small source may not be adequate to simulate the migration of a large plume under natural-gradient conditions. The di...
