Proposal of river training of a small watercourse in the basin of the Morava
Mlčochová, Zuzana ; Smelík, Lukáš (referee) ; Uhmannová, Hana (advisor)
The thesis is concerned with an appraisal of capacity of channel and design of suitable measures for environmental protection. Solved segment is located in the channel of Český potok in RK 0,000 – 6,366. The channel is flowing through villages of Čelechovice na Hané, Smržice a Držovice in solved segment. Within own solution the locality was divided into three partial sections, which is enabling clearer description of the proposed measures. Flood measures are proposed in several variants for each partial section. Calculations of flow capacity and water surface for the selected N-year flows were performed by using the program of HEC - RAS 4.1.0. Proposed solutions to flood measures are processed in the drawings documentation.

Flood Control Measures Design in the Březnice Creek Basin
Zárubová, Kamila ; Menšík, Pavel (referee) ; Starý, Miloš (advisor)
This thesis deals with the flood control. In particular, the design of a set of small water reservoirs with retention effect (polders) and their effect on flood flows. The work is divided into two parts, the first part refers to the bachelor thesis. In this thesis is description of the catchment, rainfall-runoff process and the evaluation of the ratio. That was got the necessary information for the design of polders. This is an abbreviated repetition of the contents of the thesis, which is a continuation of this work. The second part deals with the specific design of two reservoirs, including hydro calculations and drawings. For this work were used ArcGIS - ArcMap, Hydrog and to create drawings AutoCAD 2010.

The protection of small village Světnov against rural zone water
Humlíček, Aleš ; Novotný, Jaroslav (referee) ; Milerski, Rudolf (advisor)
The aim of this thesis is to propose appropriate flood protection measures in the small village Světnov, calculate the critical flood of guideline for very small basin and insert the data into the program HEC-RAS 4.1.0, where they will be further treated in order to find the most appropriate and effective solutions. As flood control measures will be designed two dry polders east of the village. Dikes should be designed so to be able to accommodate 100-year flood, which will be calculated according of guideline for very small basin. Of the materials community, we know that we need to convert flood into the existing pipeline, which is able to accommodate 1 m3/s. The thesis will design solutions dams, sewage channels and function objects in the program AutoCAD 2008.

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 protection in urbanized landscape
NEUBAUER, David
This thesis deals with the problems associated with floods and various kinds of protective measures. These measures should help to reduce the damage caused by floods and protect people on their health and lives. The work includes theoretical and practical part. The reader will find the theoretical concepts associated with floods and flood control measures, which are described individually. The practical part contains one selected area which is characterized in detail. The list of references from which it was drawn is given in the final park of work. The work also includes photographs of the selected river basins and map outputs for a better idea of the selected location.

The costs of water retention in landscape and wetland creation in Czech republic.
ČERNÝ, Jan
Different types of man-made retention systems (polder, small water reservoir, large water reservoir) have been characterized by means of their retention potential and cost of retention per one cubic meter. As part of these man-made retention systems, wetland area has been created. Its acreage and build expense has been counted up inreference to total area, which differed within various types of retention systems. The results of these calculations, Hessenian method, and the metohod of agricultural land use were used to evaluate natural river basin and its retention potential. The calculations reveal, that model locality of natural river basin has the lowest value, when used for agriculture cultivation. Hessenian method showed the highest value. The expense of substituting the natural retention of the model locality with different man-made retention systems is estimated to be 0.5?1.6 billion CZK.
