How many rivers are there in Europe?

It is difficult to give a precise answer to how many rivers there are in Europe due to the lack of a universally accepted definition of what constitutes a river and variations in naming and counting practices across different countries and regions. Rivers can be defined based on various factors such as length, flow rate, hydrological characteristics, and connectivity to larger water bodies. Considering the main rivers and tributaries, the number could be in the thousands or even higher, while smaller streams and watercourses may further increase this count significantly.
