The run-off trend of spring floods in Sweden has been changed in recent years. It has been reduced snowfalls and there are fewer spring floods now, especially in southern part of the country. By researching flowing volumes and meteorological circumstances of Kalixälven in the northern part and Emån in southern part in Sweden under the recent 50 years, we found that run-off peak in the southern part has been moved from spring to summer, because of the heavy rains in summer that have been increased. Additionally, the air temperature average in whole country tends to be increasing.
