Various predictive models were developed using the site data generated from field surveys conducted in 1978 and 1979. New layers in the GIS containing these locations were produced and new maps showing the areas with the highest probability of site locations were created. These areas of higher probability of archaeological sites have a high correlation with areas that are threatened by current gravel mining activities in the area. Current research involves analysis of aerial photography and site surveys using GPS in these areas predicted to have higher site potential. The Roman era sites tend to cluster along the rivers in flat bottomlands, and also along the Roman roads, which also tend to follow the lower elevations.
Celtic sites tend to be more in uplands and near the Celtic hillforts on the hilltops.
The largest single area of high probability of Gallo-Roman sites in this model is the area shown below, next to the river, where the Roman villa was located and later destroyed. The gravel operations continue to work in the area, and researchers are trying to locate additional sites using these techniques before they are destroyed.
