This diploma thesis deals with assessment of flood protection measures in Břeclav. Hydraulic calculations of proposal flood events were carried out using 2D numerical model of water flow. Several simulations took account of construction phases and different values of proposal discharge. The hydraulic calculations were computed for river Thaya including its relief branch. The results were processed in the form of inundation maps, depth maps and they were recorded in longitudinal profiles of rivers.

The case study is the Huallaga bridge, located in the San Martín region, Peru.Based on the geomorphological, hydrological and hydraulic data of the study area and after carrying out an analysis of the different equations for local, general scour; Numerical modeling was performed on the HEC-RAS and IBER software in order to calculate the depths of the scour.The following results were obtained: That in the local scour calculations, the scour depths were less with the 2D software, compared to the values obtained in the 1D software; while in general scour calculations, we obtain greater depths when modeling with 2D software, compared to the values obtained in 1D software

The Diploma Thesis consists of research and design part. The content of research part is description of dry reservoirs and theory of 2D modelling. The design part of the work deals with the hydrotechnical study of possibility of building a dry reservoir Blučina in two variants of designs of reservoir with objects. The design contains simulations of 2D numerical model of reservoir made in program SMS-SRH of both designed variants. The result is evaluation of both designed variants and recommendation of better option for a possibility of construction in the future in terms of the transformation of the century-flood wave.

This master’s thesis deals with exploring present conditions in Maloměřice-Brno during floods which is followed by design of antiflood protective structures. Research uses coupled 1D/2D numerical model for flood discharges Q1, Q5, Q20 and Q100 computing. In the last step maps of hazard and draw documentation were made.

Master's thesis deals with present state assessment of flood hazard on rivers Svitava and Svratka in the southern part of Brno. Flood discharges Q5, Q20, Q100 and Q100N were solved using coupled 1D/2D numerical model. All results were evaluated as maps of hazard.

This thesis deals with the assessment of the current state of flood protection in Brno, Pisárky and the Staré Brno district on the Svratka river at km 37.053 to 41.116 and the subsequent design and assessment of flood protection measures. Hydraulic calculations were carried out using the coupled 1D / 2D numerical model of water flow to pass peak flows Q1, Q5, Q20, Q100 a Q100 unaffected. The results are processed in the form of inundation maps and drawing documentation.

The Master‘s thesis deals with the assessment of the current state of flood protection in the rivers and floodplains of Svitava (km 0.000 - 2,050) and Svratka (km 26,370 - 33,963) in Brno. Using a combined 1D and 2D numerical model of water flow, hydraulic calculations of the peak flows of Q5, Q20 and Q100 were performed. For calculation, HEC-RAS 5.0.6 was used. The outputs were processed in the form of flood hazard maps and drawing documentation.

The aim of master‘s thesis is to assess the current state of the degree of flood protection on the basis of hydraulic calculations for different flood scenarios that correspond to the maximum culmination discharges Q1, Q5, Q20, Q100, Q100 unaffected in areas Komin and Kníničky on the Svratka at km 45.477 to 47.810. Hydraulic calculations were carried out using the coupled 1D and 2D numerical model. The outputs have been processed in the form of maps of depths and speed floodings.

The thesis deals the assessment of the resistance of the existing boulder chute in the river Lomná. At km 1,9 Boulder chute is located in the village Jablunkov. Surface resistance of boulder chute is assessed newly on the basis of non-dimensional shear stress for particle on arbitrarily sloped bed. The calculation of 2D flow was computed by HEC-RAS. On the assessment of resistance was proposed reconstruction of boulder chute.

The diploma thesis deals with the proposal of measures on the Svratka stream in the cadastral area Český Herálec and Herálec na Moravě. The aim of the diploma thesis is to propose appropriate flood protection in the Herálec urban area and to elaborate proposals of nature friendly measures outside the municipality’s built up area, which will enable the renewal of the ecological functions of Svratka in the spring area. In the diploma thesis the assessment of the current state of the watercourse in the analyzed locality was caried out and also the assessment of the capacity of the watercourse and the objects on there. Furthermore, the flood levels and its areas were determined. Hydraulic water flow calculations were performed using the 1D and 1D/2D numerical model. For calculation, HEC-RAS 5.0.3 was used. When processing a 1D/2D numerical model, a manual describing the progress of work in the HEC-RAS 5.0.3 program was also created. On the basis of the results from the numerical model, a proposal for flood protection measures in the urban area and nature friendly measures in the extravilan was carried out.
