Contaminant transport to public water supply wells via flood water retention areas
Contaminant transport public water supply wells flood water retention areas
2009/12/8
The essential processes and mechanisms of the transport of contaminants from a river to a well field via a flood water retention area are presented. The transport is conceptualized as a succession of ...
Investigation of a parameter estimation method for contaminant transport in aquifers
Investigation parameter estimation method contaminant transport aquifers
2009/12/4
Real world groundwater aquifers are heterogeneous and system variables are not uniformly distributed across the aquifer. Therefore, in the modelling of the contaminant transport, we need to consider t...
