A review on modelling bacterial transport in soils

Abstract

Abstract: Most studies on bacterial transport in soils were carried out in columns under controlled conditions, and the results were various, reflecting the need of standardizing the method. Other methods were also used in conjunction with microscopy to examine the transport at pore scale. Mathematical models based on convection dispersion equation were developed to simulate bacterial transport.Within specific limits, these models could simulate the major behaviors of bacterial transport. However, they neglected some parameters such as the growth and death of bacteria.The theoretical development, experimental size, scale exchange and modeling for predicting bacterial transport at field scale should be further studied.

Key words: Bacteria, Transport, Sorption, Model, Column experiment
