Innovation: Briefly: Radio links monitor river's health

Hull University is setting up 12 monitoring stations to observe conditions in the Humber estuary in real time. Three will be placed on floats across the river's mouth. They will use radio links to feed back information on tidal flows and the quantities of solids and chemicals moving in and out of the estuary. The findings of the Humber Observatory will be used to assess the effects of changes to the estuary and improve decision-making on developments around it and the North Sea.
