    Groundwater flow and advective transport were simulated in a heterogeneous synthetic aquifer. These simulations were conducted when the aquifer was fully defined and when it was characterized using a limited amount of hard and soft data (hydraulic conductivity data and soil classifications). Co-kriging was used to combine the data types when estimating the hydraulic conductivity field throughout the aquifer. Results of the flow and transport simulations showed that soil classifications were useful in characterizing the hydraulic conductivity field and reducing errors in statistics describing the plume.
