An analytical model is developed which can describe the hourly temperature variation in rivers. The model is composed of two parts, a day and night solution. The analytical solution is based on a linearization of the net heat exchange term at the air-water interface. The incoming solar radiation is approximated by a sine function. Comparison with experimental data is very good.
