Lateral solute mixing processes — A key for understanding field-scale transport of water and solutes

摘要: Abstract Lateral mass exchange mechanisms affect the spreading of solutes in main direction flow. Modeling vertical solute requires therefore an understanding lateral transport across regions varying velocities. Experimental observations show that variable extent and rates mixing cause dramatically different regimes, which can neither be predicted nor explained mechanistically terms known state variables. In this paper, we various flow regimes are sensitive to relative magnitudes particle Different concepts discussed, postulate physically meaningful parameters describing would a clue for deciding priori regime is appropriate particular soil or horizon.
