the river aure flows through bayeux, offering panoramic views from a number of locations. the aure has a relatively high level of turbidity and the speed of its brownish water is moderate because of the slight slope of the watercourse, although where it is narrow in places like the centre of bayeux, higher surface speeds are generated. in the centre of bayeux near the bayeux tapestry museum, ph levels were measured at 8.35 and the electrical conductivity of water was tested at 37 microsiemens per centimetre. turbidity was measured at 13 centimetres by the secchi disk method. at this point of reference, flows are generally of the order of .
