Fig 57. Sketch map showing why Godmersham and Wye arose where they did on the Stour. At A, the gravel patch, the river has a hard bed and can be forded. A village therefore grew up here. At B, the clay part, the river has a soft bed and cannot be forded. The land is wet in winter, and the banks of the stream may be washed away. It is therefore not a good site for a village
