This work elaborates on the application of a model to assess the pattern of groundwater pathlines and travel times in steady-state groundwater flow around a well field in the vicinity of a river in the Netherlands. The flow pattern is verified by matching the chloride concentrations, derived manually from the flow pattern, to the concentrations monitored at a single time instant. The observed concentrations compare good with the modelled ones. As a second verification step, a solute transport model is used to simulate the concentration variation in wells in time, due to the transient variation in the river concentrations and also the transient well rates. As the well concentrations modelled by the solute transport model compare reasonably to the observed concentrations in wells, it is concluded that the flow pattern is sufficiently verified for subsequent use in other studies. |
