| Popis | Modelling in hydrology has been developed for many years and a plenty of models various in purpose and complexity have been available nowadays. The AIZM flood model (riginally in slovak 'Alternatívny Indikatívny Záplavový Model') is an alternative 'viewer', kapable of providing flood extends, as well as the field of depths, with minimal demands on the input data and computing time. The model is based on chaining of several toolsets within the Model Builder. Despite the availability of flood extends modelled by hydraulic models, many of river sections in the Czech republic lack the outputs of hydrological models. On the basis of available hydrological measurements, the AIZM model could be used to generate at least a rough (but reliable) estimate of potential flood extend. In order to gain reliable outputs, a comparation of the AIZM outputs with the hydraulic models‘ outputs is necessary. Therefore, 30 sections of czech rivers were chosen. All of them were sorted out into 6 categories according to the course of their channels. This way it was possible to determine which category of stream the AIZM model is suitable for. The comparison was carried out regarding the imput data of digital model of relief (DMR 4G and DMR 5G) and for floods with periodicity of 5, 20 and 100 years. The UAV technology provides a good possibility for the AIZM model from two perspectives. Firstly, the photogrammetric measurements may provide more accurate data of the digital model relief which is a crucial input influencing the final output. Secondly, UAV scanning offers detailed information on real flood extends. Such images, together with measurements of water stages, may be used for the purpose of verification whether the AIZM model provides reliable outputs for a particular river section. The introduced tool is a 'living organism' which is being tested and developed. It is going to be further modified to be able to generate as accurate and reliable outputs as possible under assumption that the simplicity of control will remain. |
