what country, countries, county, counties does the River Thames flow through?

Answer 1

The river basin is conventionally divided into four areas: the tidal, lower, middle and upper Thames. The Upper Thames flows from Thames Head (its source) to its confluence with the River Windrush at Newbridge, falling 46 metres over a distance of 64.7 km [4]. The Middle Thames runs through the first major cities along the river — Oxford (population 120,000), and into Reading [5]. The first major discharge of effluent directly to the Thames occurs in this stretch of the river — below Oxford.

The lower Thames runs from the confluence of the River Kennet in Reading to Teddington weir — the official upper tidal limit of the Thames [6]. In this stretch of the river, the flow of the Thames is supplemented both by springs and seepages rising from the chalk aquifer, and from tributary flow; run-off from clay is important near the Teddington weir. At Teddington, the freshwater flow in winter may exceed 30,000 Ml/day; but this flow decreases significantly in summer, and has been known to dry up completely (e.g. during the 1975/76 drought) [7]. Under normal conditions, the Teddington flow is maintained at a minimum of 800 Ml/day, but this may be reduced to 200 Ml/day during times of drought. Urban run-off, discharges from major sewage treatment works, and tributary water of only ‘fair’ quality all contribute to declining water quality in this stretch of the river, as compared to the upper reaches.

The tidal Thames, from Teddington onwards, flows through central London, widening from less than 100m in the upper reaches to more than 7 km at Southend. Discharge of treated effluent from London occurs mostly downstream of the city itself. Water quality in this final stretch of the river is carefully monitored
