2017 / 3. szám - MANAGING ENVIRONMENTAL RISKS - FLOOD PROTECTION EXPERIENCES AND COOPERATION IN THE DANUBE RIVER BASIN - Engi Zsuzsanna: Flood hazard modelling of the River Mura based on the silting up processes of the inundation area
88 Hidrológiai Közlöny (Hungarian Journal of Hydrology) 2017. 97. évf. 3. sz. Comparison using a GIS method Old historical maps were used for comparison. 7 digitalized river paths from 1785, 1860, 1880, 1920, 1976, 2002 and 2014 were analysed. The conclusion was that the Mura flows also in the old river paths and uses them for the conveyance of discharge in the inundation area. The old Mura river paths were identified in two experimental areas from the time of the Second and Third Military Surveys (Engi 2016, Engi et al. 2016a) (Figure 9). The effect of flash floods Simulations were run to discover the effect of flash floods on the development of the inundation area, specific discharge and velocity. The results were shown on flood maps of the four experimental areas in characteristic time steps and the flood wave propagation was described {Engi 2016) {Figure 10). Figure 3.
