Modeling and simulation of cadmium transport influenced by high degree of saturation and porosity on homogeneous coarse depositions

摘要

Thispaper monitors the effect from degree of saturation and porosity on the migrationrate of cadmium in homogeneous coarse formation. The study expresses the rateof coarse homogeneity reflecting on the deposition of cadmium in deltaicdepositions. Other studies were carried out on a particulars soil formationthat could not predict comprehensive migration rate of cadmium concentration incoarse depositions. These were monitor on deltaic location were coarsedeposition are predominant thus degree of saturation and porosity were observedto influences cadmium concentration in the study area. Porosity and degree of saturationwere the major effect that determine their variation of cadmium concentration,the derived solution were subject to simulation, these values express linearconcentration of cadmium, but with variations at different depth to phreaticbed, the study has express the influences from porosity and degree ofsaturation reflecting on cadmium concentration, experts in pollution transportwill definitely apply this tools to monitor the formation characteristicsinfluences on cadmium transport in deltaic depositions.
