Assessment of erosion and flood control measures effectiveness in small catchments
Feltl, Jakub ; Podhrázská,, Jana (referee) ; Krejčí,, Lukáš (referee) ; Doležal, Petr (advisor)
Thesis is about assessment of erosion and flood control measures effectiveness, especially of broad base terraces. The main contribution is a new method of flood effect evaluation of these measures. This is solved by modern programs and geospatial technologies such as ArcMap and HEC - HMS. Economic assessment in alternative solutions of flood and erosion control effect is a main result which leads to optimal technical proposal. The proposed, relatively fast, method can be successfully applied in practice.
The propagation of the open surface waves
Kajánková, Dominika ; Haluza, Miloslav (referee) ; Fialová, Simona (advisor)
Water covers majority of planet, waves, forming on its surface, are without any doubt part of it. The aim of this work is to make you familiar with types of waves at the free surface, how they propagate and how can we prevent their propagation.
River regulation and flood protection
Pechová, Kamila ; Petrula, Lubomír (referee) ; Duchan, David (advisor)
This bachelor thesis is focused on a proposal for adjustment of a flow with a consideration of an anti-flood protection and a revitalization the Svitava river in Bílovice nad Svitavou. Based on a course of the height of the water level discovered from a computational model from the HEC-RAS program is designed an anti-flood protection of the flow and this way the spilling of the river from an intravilan is prevented.
Study of possibilities protection of small village against rural zone water
Holý, Jan ; Vrba, Jan (referee) ; Milerski, Rudolf (advisor)
The thesis deals with protection against water from rural areas with a focus on the protection of the village Chrudichromy. The chapters are structured so that outlined the general theory of flood protection and design protection in the cadastral Chrudichromy. The design consists of project protective reservoir.
Assessment of the Options of Increased the Flood Protection
Adam, Karel ; Golík,, Pavel (referee) ; Uhmannová, Hana (advisor)
The work deals with the assessment of the stream Chribska Kamenice current state in the village Vsemily urban area. The aim of the project is the assessment of capacity and the current state of the stream-bed. Based on an assessment measure there has been designed the improvement suggestion of the current state and flood protection increasing in close neighbourhood.
Assessment of the water flow in the Odra river basin
Mláděnka, Jakub ; Vysloužilová, Lucie (referee) ; Uhmannová, Hana (advisor)
The aim of the bachelor thesis is to describe and evaluate in detail the current state of the Luha river and the objects connected with it, in the interest section – river kilometer 0.000-2.853 in the cadastral area of the Jeseník nad Odrou. Part of the work is to assess the capacity of the river flow in the locality and to propose ideological measures that would increase it to the design value of the 20-year flow. The calculation of the flow rate is performed by using the 1D mathematical model HEC-RAS for selected N-year flows. On the basis of the results of the flow rate, the assessment of the capacity of the channel and the objects in the solved section, two variants of continuous river basin adjustment are proposed to improve the current state of the channel and to increase the flood protection of the neighboring area.
A study of erosion control system using biotechnical conservation measures
Moravec, Jiří ; Sobotková, Veronika (referee) ; Dumbrovský, Miroslav (advisor)
The objective of the bachelor thesis was the study of soil erosion control with application of system of semi-natural measures in chosen small catchment. Digital elevation model was generated and average soil loss was determined by ArcGis tools at each erosion parcel . Design of erosion control at chosen erosion risked locality was create in Microstation software and InRoads utilities. As a type of enviromental erossion control mesures was chosen a system of a earthfill dams with the sedimentation area in combination with grassing. The thesis efforts to point the differences between the possible optimal solution and a compromise solution which respects the requirements of agricultural entities. The solution respects the trend of water retention in landscape and use of low cost measures.
Flood control measures in the Loučka Catchment
Hadaš, Zdeněk ; Marton, Daniel (referee) ; Starý, Miloš (advisor)
This thesis deals with the river basin flood protection Loučka. The aim to assess the need tu supplement flood control measures in the watershed. The first half deals with exploration of river basin, providing geographic factors and obtaining information on the topic. The second part deals with the establishment and application of rainfall model to solve the problem. For schematisation basin was used ArcGIS program. Rainfall simulation process were calculated critical duration of rainfall intensity and spare set of N-year flows. It was by searching for critical points and assessed for possible overflow.
Extreme hydrological events in the context of urban planning
Klimeš, Zdeněk ; Dráb, Aleš (referee) ; Duchan, David (advisor)
The purpose of the bachelor thesis was to describe known extreme hydrological events and potential attitudes to minimalize their negative impacts. The thesis was written as literature recherche from different points of view, not only from a one-sided technical or ecological point. It proceeds systematically from describing the historical evolution of the subject matter through the presentation of global ecological problems, outlining the legislative background and the findings from specialised literature, to the examples of current trends. In view of the fact that the issue is so broad, the thesis treats only certain parts in detail. The subject of interest is the demonstration of separate measures against floods and droughts and the effects of their synergy concerning the minimalization of the repercussions of extreme hydrological events.
Identification of retention volumes in Brno
Man, Radim ; Roth, Tomáš (referee) ; Jandora, Jan (advisor)
The aim of the diploma thesis is to assess whether it is possible to use a newly planned transverse structures as a polder dam in the area of interest and to connect other flood protection elements. Furthermore, to design and dimension inflow and outflow objects to reduce the flow in the Svratka river as effectively as possible during the culmination of the flood. The last part of the work is devoted to the evaluation of the economic efficiency of the implemented measures. Part of the work are hydrotechnical calculations of the inlet and outlet object, which are performed using the program HEC-RAS and technical drawings of buildings.
