Design of weir reconstruction
Němcová, Denisa ; Julínek, Tomáš (referee) ; Uhmannová, Hana (advisor)
This bachelor thesis deals with the design of the reconstruction of a solid weir on the Oslava river, in the town of Oslavany. The introduction describes the site of interest and the choice of a suitable design solution for its reconstruction. There are several types of movable weirs and fish ladders described theoretically. Further on in the thesis, the state of the objects on the flow and the state of the river basin of Oslava, in the area of interest, are described. Another part of the thesis deals with the design of a movable baying structure (a hollow flap). An impact assessment of the current and newly proposed weir on flow in the HEC-RAS program was carried out. The project also includes the design of fish ladder and an evaluation of the stability of the newly designed construction.

Assessment of runoff conditions on flow in the cadastral area of Dašice
Janovská, Michaela ; Vysloužilová, Lucie (referee) ; Uhmannová, Hana (advisor)
This thesis is aimed at assessment of drainage conditions at the river Loucna in the cadastral area of Dasice. The examined section is 3,88 km long and runs through out of the city and in the city of Dasice. On the left bank of the river there are several historic buildings that are potentially at risk for 100 years of flow. Capacity assessment is performed using the 1D mathematical program HEC - RAS in which the flow model is created and the calculation of the flow rates for individual N - year flows. On the basis of the results of the program is conducted conceptual desing of flood protection measure. At the same time is conducted conceptual desing of fish ladder on the weir and a sluice closure on the intake for the race.

Revitalization of the selected section of the River
Bakala, Filip ; Petr, Pelikán (referee) ; Šlezingr, Miloslav (advisor)
This thesis deals with revitalization of the selected part of river Drevnice. Main scopes of the work are proposals of fish passages through migration barriers. The work is conceived on four levels. The first of them is dealing with the general characteristics of selected segment and with description of objects on watercourse. The second level is dealing with revitalization, where the basic information about migration and efficiency of fishes are described. In this chapter basic distribution of fish ladders is included. In third part, which is the most comprehensive, I design a boulder fish ramp and bypass channel. The last chapter contains drawings documentation of watercourse Drevnice and my own proposed revitalization elements.

Design of weir reconstruction in Oslavany
Němcová, Denisa ; Smelík, Lukáš (referee) ; Uhmannová, Hana (advisor)
This diploma thesis deals with a design of the reconstruction of a smixed weir on the Oslava river in Oslavany town. The introduction describes the site of interest and the the occurrence of ice events. There are several types of fish ladders described theoretically. Further on in the thesis there is desribed the state of the objects on the flow and the state of the river basin in the area of interest of Oslava river. Next part of the thesis deals with the design of a movable baying structure (a hollow flap) and fish ladder type bypass channel. An impact assessment of the current and newly proposed weir on flow in the HEC-RAS program was carried out. The project also includes the basin adjustment in overweir and an evaluation of the stability of the newly designed construction.

Design of gated weir on the Želivka river
Staněk, Tomáš ; Roth, Tomáš (referee) ; Julínek, Tomáš (advisor)
The purpose of the diploma thesis „Design of a movable weir on the Želivka river" is a design of the reconstruction of a fixed weir in Soutice village on the river Želivka at km 1,639. The first part of the thesis deals with the localization of the area of interest and a description of all documents needed for the weir design. The first part also includes a short search of the considered structures, the findings of which are further applied in the design of a movable weir structure. Furthermore, the work continues by determining the design flow and selecting a suitable structure of the fixed weir substructure and movable closure, which is fitted to the substructure. Based on the selected types of structures, hydrotechnical calculations are performed, which also include a partial assessment of the weir stability. The thesis ends with a technical description of the proposed objects and a final evaluation of the determined achievements of the work. Part of the study is a drawing part documenting designed objects.

The revitalization project of the selected section of the watercourse
Skřížala, Lukáš ; Blahuta, Jaroslav (referee) ; Šlezingr, Miloslav (advisor)
Bachelor thesis deals with revitalization in the selected section on the watercourse Ondřejnice. Purpose of the revitalization is especially the removal of the migration obstacles creating conditions for the natural development of the trough, without any need of standard maintenance by the flow manager. In the bachelor thesis have been replaced some stone steps by the boulder slip, the wooden gradients have been replaced by some new wooden steps with holes for the migration of animals. Then were in the watercourse designed some Fish shelters. At the places where the gradient adjustment will take place, will be designed a new vegetation accompaniment. By the design of the revitalization measures there will be no worsening of the drainage ratios.

Revitalization of rivers on the way fish-passing facility building
Banzetová, Diana ; Princ, Michal (referee) ; Milerski, Rudolf (advisor)
The bachelor thesis is consisted of two parts. First part is about causes of fish migration and revitalization of streams by building of fish ladders over migration barriers. There are described two basic types of fish ladders, natural and technical including main features. Further it is about design, parameters and check of function of fish ladders. At the end there is summary of legislation and funding options of construction. The second part is dedicated to specific fish ladder. The fish ladder is situated to weir on the river Jihlava in Cvrcovice village. Bachelor thesis is here dedicated to description of one particular fish ladder based on actual fish stock. In this part there are hydraulic countings and specific data acquired of HEC-RAS program, in which was fish ladder designed and tested in simulated run based on hydraulic conditions.

Adjust the flow - design migration path
Špaček, Jakub ; Marková,, Jana (referee) ; Šlezingr, Miloslav (advisor)
This thesis describes the design of fish ladder on the river Mohelka near the village Chocnějovice. The first section describes the general characteristics of the river-basin and the selected section. It is written introduction to the design, construction and service of the fish ladder. For the task were developed two alternatives. These alternatives were described and compared each other. Included are the input and output data of the given structure modeling using HEC-RAS. The last part is then researched drawings to objects.
