Flood and erosion hazard maps based on 2D hydraulic model |
Secondary abstract: |
In 2007, the European Union adopted the Flood Directive with the aim of better regulation in case of flood. The European Union member states are required to create flood hazard maps and flood risk maps. To achieve these objectives, Rules on Methodology to Define Flood Risk Areas and Erosion Areas Connected to Floods and Classification of Plots into Risk Classes were adopted in Slovenia. The two-dimensional hydraulic models, which are increasingly in use, represent an irreplaceable tool in predicting the flood extent and flood mapping. As opposed to the one-dimensional models, these models are more accurate in describing the movement of water on the floodplain areas. The development of the high-quality hydraulic model is dependent of the topographic data, boundary conditions and roughness of the surface. The more reliable the data collected, the more accurate the model built. In the thesis, the development of the flood and erosion hazard maps in the case of the Austrian Schwarzaubach River is shown. The hydraulic analysis was carried out by two-dimensional hydraulic software CCHE2D, which enables not only the simulation of the flow but also the simulation of the sediment transport. |

Abstract (ePrints): |
Evropska unija je leta 2007 sprejela Poplavno direktivo, z namenom boljše ureditve razmer ob poplavah. Od držav članic Evropske unije se zahteva izdelava kart poplavne nevarnosti in kart poplavne ogroženosti. Za izpolnitev ciljev je bil v Sloveniji sprejet Pravilnik o metodologiji za določanje območij, ogroženih zaradi poplav in z njimi povezane erozije celinskih voda in morja ter o načinu razvrščanja zemljišč v razrede ogroženosti. Nenadomestljivo orodje pri napovedovanju obsega poplav in kartiranju poplav predstavljajo dvodimenzionalni hidravlični modeli, ki so vedno bolj v uporabi. Ti za razliko od enodimenzionalnih modelov bolj natančno opišejo gibanje vode na poplavnih
površinah. Na izdelavo kakovostnega hidravličnega modela vplivajo topografski podatki, robni pogoji in hrapavost površja. Bolj kot so zbrani podatki zanesljivi, natančnejši model lahko izdelamo. V diplomski nalogi je prikazana izdelava karte poplavne in erozijske nevarnosti na primeru odseka reke Schwarzaubach v Avstriji. Hidravlična analiza je bila izvedena z dvodimenzionalnim hidravličnim programom CCHE2D, ki poleg simulacije toka omogoča tudi račun transporta sedimentov. |
