Restoration of a Wetland near Sedmihorky in the Bohemain Paradise Protected Landscape Area
ŠŤASTNÝ, Vojtěch
This work presents a grant application for a restoration project of a wetland near Sedmihorky in the Bohemian Paradise Protected Landscape Area. It presents a general description of the locality, its history and evaluation of earlier relevant studies. A proposal of revitalizing the wetland is presented, being based both on earlier studies and the author's own observations and measurements. The proposal includes the time schedule of the restoration, financial balance sheet and visualized target state of the locality. This thesis will also serve as a key background document in the elaboration of the project blueprint by the Nature Conservation Agency of the Czech Republic.

Influence of drainage systems in the basin water regime
NOCAROVÁ, Hana
In this thesis I generally address draining systems and their influences on the water regime of a river basin. In the first part I describe the history from ancient times to the present, development in the world and in the Czech Republic at the range from 2000 years before Christ to the current systems. The thesis also explains basic terms, such as the content of agricultural ameliorations, terms relating to dewatering, purposes and division of draining systems, methods of dewatering actions, effects of water-logging and their consequences. At the end the thesis describes the impacts of building drains for draining off, dewatering and floods and the impact on the environment. The objective of the thesis is to describe the impacts and influences of drainage on the water regime of a river basin and the associated problems.

Vliv náhradních biotopů typu tůně na ochranu podobných přirozených stanovišť v krajině
Hájek, Jiří
Studie pojednává o nezbytnosti vody jako média pro život na Zemi. Zabývá se ekologicky významnými vodními plochami a způsoby jejich ochrany. Z managementu ochrany a péče vyvozuje základní důvody pro hledání alternativních přístupů akumulace vody v krajině. Voda v krajině a její význam je jednou ze stěžejních kapitol rešerše, navazuje na historii vody v krajině. Důležité je pojednání o současnosti, a to zejména z pohledu zvyšování deficitu vody v krajině, zazemňování mokřadů, regulace vodních toků nebo melioračních opatření. Druhou částí práce je definice a typizace umělých vodních biotopů včetně historického vývoje v krajinářských úpravách. Z typizace umělých vodních děl se dostáváme k možnostem technologických řešení typu "biobazénů" a "přírodních koupališť" jako alternativních řešení při ochraně přirozených stanovišť.

Revitalization of major drainage facilities and technically modified streams in agricultural landscape managed by ZVHS.
ŠTĚPÁN, Vladimír
The aim of this work is to describe the revitalization of the water, its development, possibilities and patterns as measures that are aimed to improve the hydrological stability of farmed land disturbed inappropriate water structures, such as the amelioration and technical flow adjustments. There are also described specific examples of restoration measures for streams in the scope of Agricultural water management. Examples were selected to illustrate a different approach and different options for the revitalization plan of the watercourse. Implementation of rehabilitation measures have been addressed in every workplace in a similar manner, but had a different course, and their specific problems.
