The focus of Dr Halkon's research is looking at how people have adapted to the changing landscape as the waters rise and recede from the East Yorkshire countryside.

He said: "Rising water levels is not always a bad thing. We have found evidence of axes from Wales dating back to the Neolithic period which show that the river opened up the area for trade.

"By studying lots of clues in the ancient landscape we have been able to put together maps of the valley showing how much of the land was underwater."

Dr Halkon says understanding how the landscape was then, can help to determine how it might be in the future.

He said: "Throughout time there has been a cycle of global warming and cooling and associated variations in sea level.

"Two thousand years ago this East Yorkshire farmland was under water as part of the Humber estuary. The present rise in global sea levels may mean that the landscape is reverting to the way it was in the Iron Age. This is a natural cycle, although according to most scientists human intervention is undoubtedly exacerbating this pattern."
