The River Tees is located in the northeast of England, flowing through the counties of Durham and North Yorkshire, and originates in the Pennines, flowing eastward into the North Sea at the town of Teesmouth
Characterized by steep gradients and fast-flowing, turbulent water, creating a deep, U-shaped valley through the erosive power of flowing water over time
At Teesmouth, the river widens into an estuary as it meets the North Sea, with significant tidal influences leading to the formation of mudflats, salt marshes, and sandbanks
Historically, the River Tees played a crucial role in the industrial development of northeast England, with numerous factories and industrial sites located along its banks
