Article introduces presentation portal “Voda v krajině“ (www.vodavkrajine.cz) as an information source about natural water retention measures.
Hydraulics, hydrology and hydrogeology
Summary Flood risk of levee protected areas stems from the possibility of levee failure due to overtopping, breaching or uncontrolled seepage. In most cases, levee breaching leads to highest damages as such events occur suddenly and can hardly be forecasted. In this article, levee failure is referred to levee breaching only. Whenever levees break during… Read more »
Many professionals deal with water quality monitoring in the Czech Republic with various goals and various quality of gathered information. The Czech Hydrometeorological Institute (CHMI) has built and developed a unified longterm monitoring system providing comparable high quality data at a nation- al scale.
Hydrosphere is facing a global water crisis caused by uneven availability of fresh water in time and space, overuse of resources, environmental degradation and frequent occurrence of floods and droughts.
The plenary session of the International Association of Hydrological Sciences took place in Prague and has been approved Prague Statement
The Czech capital city had in the period between June 20 and July 2, 2015 the honor to host the 26th General Assembly of the International Union of geodetic and geophysical (International Union of Geodesy and Geophysics, IUGG), on which showed an interest in nearly 5,000 scientists from around the world.
The article deals with the influence of barometric pressure changes on water levels in monitoring wells and other groundwater observation boreholes. An analysis of the problems involved in measuring the groundwater level was performed.
Ecology determined the dilution factors for the KB Alloys facility over ten years ago. The development document record is not clear as to the method used to determine the values. Ecology made an attempt to model the conditions using CORMIX 6.
Basic hydrological data are provided for any profile of the river network and serves as a basis eg. for the issue water management decisions, etc.
Under the project New procedures of optimization of integrated protection area systems in the context of their economic sustainability, analysis of plans of collective equipment was done within the complex process of land consolidation based on data from all branches of the State Land Office in the Litava basin.
The estimation of the extent of inundations is enabled by methods of physical and mathematical modelling which have been developing for many years. Increasing accuracy, related to precise measurements, demands higher computing capacity and more time.
In the Czech Republic long-term protection of localities suitable for surface water storage (LASW) is done. Currently the number of them is 65; in the near future this list will be updated. The protection of these areas, however, has impacts on social and economic development of communities, local people and on the landscape itself, too.
Station that measures vapours Hlasivo near Tabor was built in 1957 and is the only base station that measures the vapours in the Czech Republic.
The paper deals with the regularities of groundwater circulation with respect to extremely low groundwater level occurrence, seasonal and multiannual periodicity and trends of groundwater levels, occurrence of minimal levels and their impact on the enviromental components, methods of groundwater levels forecasts.
This study investigated changes in time series of hydrological balance components using trend detection.
The article presents the applied methodology and description of the most important results achieved in the project.
Experience with measurement of water levels in TGM WRI hydrometric stations (using the system of pressure sensors)
The paper describes the experience with measurement of water levels (particularly low ones) in natural river beds using a system of sensors recording hydrostatic pressure and air pressure.
Possible compensation of negative climate change impacts using the localities for potential accumulation of surface water
The list of localities potentially suitable for accumulation of surface water (LASW) exists in the Czech Republic from the beginning of 20th century.
The BILAN model has been used in a number of research projects and hydrological studies dealing with estimation of water balance for European catchments. This paper is focused on the recent development of the model during last years. The model changes include both core development (new variables representing water use, optional calibration for a system of catchments, saving of state variables) and enhanced user interface that was extended by new graphical outputs and controls allowing interactive use of the model.
