被认为是由于生物堵塞的孔隙空间在土壤中的流动制度的变化的数值模拟。生物量的生长动力学描述的莫诺方程和水力传导率的变化，由于孔隙内的生物量的积累表示由孔隙堵塞的理论模型。该模型进行了验证，通过与实验结果进行比较，使用bacteriumBeijerinckia indicacwithin砂柱与模型参数确定从独立的实验工作。然后，该模型被应用于调查流量分流内的非均质系统组成的一些地区组成的不同的砂馏分。最后，被认为是潜在的使用控制生物量的增长，工程师在非均质多孔介质中的流动。
Numerical modelling of changes in the flow regimes in soil due to bioclogging of the pore space are considered. Biomass growth dynamics are described by the Monod equation and changes in hydraulic conductivity due to the accumulation of biomass within the pore space are represented by a theoretical model of pore space clogging. The model is validated by comparison with results from experiments performed using the bacteriumBeijerinckia indicawithin sand columns with model parameters determined from independent experimental work. The model is then applied to investigate flow diversion within heterogeneous systems composed of a number of regions made up different sand fractions. Finally, the potential of using controlled biomass growth to engineer flow within heterogeneous porous media is considered.
