QCA document. Visit the Canterbury Environmental Education Centre ( details ) and undertake one of the relevant programmes, 'Water Cycle at Broad Oak Lakes' 'Weather Days' or the 'Great Stour River Study.' The Great Stour River Study programme involves walking along a section of the river refering to maps, noting relevant geographical, man made and biological features and undertaking simple experiments (for example measure differing speed of channel flow). Visit the Virtual Tour pages to take this walk along the Great Stour, which can be used to prime or reinforce the field work.
The Photo and Map pages are a good source of secondary information. The photographs focus on the Great Stour River along its course and the maps show the catchment area, topography and geology of the Gt Stour River basin. Use the Gt Stour Case Study pages as a secondary source of information on pollution, farming, industry and development and the potential impacts upon the Great Stour. Rivers and Coasts - Main menu.
