This article presents the methods and results of an assessment of the security of water abstraction and minimum flow rates through 2050, taking into account the potential impacts of climate change on water resources and projected water demand based on socioeconomic development forecasts. The study was conducted on a national scale. Water bodies defined for water planning purposes were selected as the minimum spatial scale.
The increase in potential evapotranspiration due to warming is quite often used as an indicator of ongoing and predicted changes in the hydrological balance. However, without assessing its effect in basins with different precipitation regimes, it is not correct to consider a change in potential evapo-transpiration as an increase in actual evapotranspiration or a decrease in runoff.
The paper describes software aimed at analysing water management infrastructure and identifying critical points for water supply and assessing possible measures aimed at optimising the water supply function of the water management system. The computational procedures integrate the evaluation of the hydrological characteristics of the area, the parameters of the water management and water supply systems and the water supply requirements. The solution uses graph theory and network flow optimization (out-of-kilter algorithm is applied). The program is implemented as a PC application and equipped with a user interface.
Centrum Voda je výzkumný projekt, který hledá řešení problémů vyplývajících z klimatické změny a jejího vlivu na vodní poměry. Snažíme se nalézat odpovědi na základní otázky, jestli dokážeme zajistit dostatek kvalitní vody nejen pro potřeby člověka, ale i pro naši krajinu, zda se zvládneme vyrovnat s přívalovými povodněmi a jak dále snižovat znečištění vodního prostředí.

The paper presents a summary of input information about the research project Water towers – identification, documentation, presentation, new use. It deals with the development of tower water reservoirs in the present territory of the Czech Republic from the beginning of their creation to the present.
The paper presents the draft of the plan for drought and water scarcity in the Czech Republic. The plan is a basic document of drought protection. It serves to coordinate activities in a given area during drought and water shortages.
In our country there are at least ten water supply systems and dozens of provincial or regional group water mains, which were built in the sixties to the seventies of last century, whose lifetime presently terminate or expire in the coming years.
The seminar organized by the Expert Group Water Supply and SewerageCzech scientific water management company in collaboration with VRV (Water resources development and construction, a. S.) was held on 11 May 2016 at the company of headquarters.
