A list of the units modelled is given in table 1.

There was no defined regional stratigraphy for the Teesside area prior to modelling. The lithostratigraphy used to define the modelled geological units was defined following a literature review and initial borehole inspection. The nomenclature for the stratigraphic units, particularly the Quaternary Deposits, was chosen for consistency with previous work for the Environment Agency in the Durham area to the north (Price et al. 2007). It should be noted that the lithological consistency of the units in Teesside with type-sections from the Durham area is assumed based on borehole records and has not been verified in the field.

Surface water, including the River Tees, offshore areas and parts of the Tees Estuary that fall within the model area have been modelled as a pseudo-stratigraphic unit. Information on the geometry of the water bodies, including water depth was taken from OS topographic maps and Hydrographic Office Nautical Charts.

Made ground, including artificial man-made ground observed in boreholes and inferred from features recorded on topographic maps, has been included in the model.

A ‘Base Model’ surface has been modelled to define the lower limit of the modelled ground. This surface lies well below the base of the superficial deposits but does not include details of the bedrock geology.

Also included in the model are several Sand, Sand and Gravel, Till, Peat and Clay lenses found within various units but the majority occur within the Till sequences.
