Hidravlično modeliranje poplavne nevarnosti na izlivnih odsekih vodotokov, oprto na procese zamuljevanja : doktorska disertacija

Engi, Zsuzsanna (avtor), Steinman, Franci (mentor), Tóth, Gábor (komentor)

V disertaciji smo proučevali poplavljanje in zamuljevanje inundacijskega območja spodnjega odseka meandrirajoče reke. Z dvorazsežnim hidravličnim modeliranjem smo določili cone odvajanja pretoka na inundacijskem območju. Primerjali smo stanje poplavljanja v času konice poplavnega vala in spremembo po odtekanju poplavne vode, da bi sklepali o razvoju vodotokov in zamuljenosti inundacije. Proučevali in primerjali smo rezultate različnih raziskovalnih metod (hidravlično modeliranje, geomorfološke metode, sedimentološke raziskave, določanje starosti slojev vzorcev), da bi ocenili, kakšne posledice bi izzvale podnebno pogojene spremembe pretokov na obseg območja poplavne nevarnosti. Analizirali smo geomorfološke značilnosti meandrirajočega spodnjega odseka reke. Določili smo morfometrijske parametre zavojev in ugotovili trend dolgoročnega razvoja meandrov in vodotoka.

Izvleček

In the dissertation the flooding and silting up process of the inundation area of downstream sections of the meandering river were studied. The travel zones in the flood-plain forming during the travel time of the flood-wave were determined by using 2D hydraulic modelling. The flooded status of the inundation area was compared during the flood peak and the falling limb of the flood wave in order to get information about the changes of the river bed and the silting up of the inundation area. The results of different research methods were compared (hydraulic modeling, geomorphological methods, sedimentological analyses, dating of the layers in the sediment sample) to evaluate the possible effect of the changes of discharge on the flood hazard due to the climate change. The geomorphological characteristics of the meandering outfall river sections were studied. Morphometric parameters and the trend of long-term development of the meanders and the river were evaluated.
