Abstract: Ice discharge calculated from the running ice floes may be adopted as the quantitative characteristic of the ice regime. The quantities involved in the estimation consist of the ice coverage observed visually, the width of the water surface, the assumed thickness of the ice floes and the velocity of the latter. Terrestrial (ground) and air observations, especially photography are suited to determining the ice coverage and the velocity of the floes. Application of aerial photography is introduced on a Danube reach upstream from Budapest. Ice coverage, size and movement of ice floes were investigated from the photographs. The mean ice coverage derived from the reports of ice reporting service for the river stretches studied were in surprisingly good agreement with the values found by the exact method.
