Reconstruction of dam Ivanské jezero
Svatoš, Petr ; Beran, Ivan (referee) ; Duchan, David (advisor)
Water structure Ivanské jezero was built on the Javorník Creek back between 1905-1907. The main purpose of the dam was accumulation of high volumes of water and protection of the territory downstream. After the adjustment for higher flows on the river Kněžna in Rychnov nad Kněžnou, which was completed in 1937, the water structure lost the protective function. On the basis of an assessment made by Povodí Labe in 1993 - due to the low volume of the reservoir there is no flood wave transformation and already while flow rates greater than Q50 pass through dam, it results in overflowing the dam. To this date water structure Ivanské jezero is in very poor condition due to degradation of the binding material in the dam. The goal of the thesis is to propose a procedure for removal of the existing structure and the subsequent construction of the design and construction of a new – gravity, concrete dam. This work will contain technological removal process of current dam and possible usage options for the dam material. In the next step a new structure will be designed in the place of existing dam. After new design is completed there will be hydraulic assessment of the functional objects, hydrology and stability on the dam.

Reconstruction of gate weir on the river Bystřice in Kunčice
Svatoš, Petr ; Neumayer,, Oldřich (referee) ; Duchan, David (advisor)
This thesis is about reconstruction of existing floodgate weir on the river Bystřice in river km 17,650. In actual state (2017) there is floodgate weir with four independent flow fields. This construction is inappropriate in the locality due to the capture of floating debres on the guiding profiles of the weir boards at higher flows, which reduces the flow capacity of the weir profile and consequently the flow over banks of the river Bystřice into the village of Kunčice. As a solution, the reconstruction was chosen as a movable structure with automatic water level control – rubber weir. This proposal is then compared to the previous investor's proposal on the economic, hydraulic and operational aspects.
