Catalogue of green water retention measures in the landscape and its application in the web map application
A catalogue of green water retention measures in landscape represents one of the results of long term project financed by the Ministry of Environment. The main goal of the catalogue was to summarize a set of measures with positive effects on water retention of landscape, with low impact on ecological status of water bodies.
Study on the assessment of the effect of nature-friendly measures in the Olešná in Pelhřimov catchment area using the BILAN, HEC-HMS and HYPE models
A catalogue of natural restoration measures was created within several research programs under Ministry of the Environment of the Czech Republic, especially in the program for hydrological draught mitigation. As a next step suitable catchments for their application were identified. With use of hydrological models, the effect of designed restoration measures on three aspects of hydrological regime was assessed.

Past tests of nuclear weapons in the atmosphere, nuclear energy facilities and tritium of natural origin are main sources of tritium in the environment. Thanks to its presence in environment and its favourable properties, tritium is used as a radiotracer.
Mathematical models have been used in hydrology for decision making support for many years. They allow the realization of virtual experiments that can be done empirically either very difficult or not at all. The SWAT model, developed in the US, has gained world wide popularity but its application in the Czech Republic is quite rare yet.
The use of automatic samplers for detailed monitoring of substance concentrations and balance is nowadays an important part of special monitoring of surface waters. The average results of routine monitoring (consisting of point samples) are often underestimated over the real situation.
Changes in chemistry and biology of the mesotrophic water reservoir after an extraordinary level decrease
Opatovice Water Reservoir is an important source of drinking water for the district town of Vyškov in South Moravia, northeast of Brno. After a partial decrease in the level in 2012 and after a significant reduction in 2017 there were marked changes in the chemistry and in the biology of the tank.
Significant adverse effects of measures for the use of heavily influenced water bodies: experiences and examples from abroad
In April 2018, an international workshop was held in Brussels to assess the significance of adverse impacts of planned measures for use or wider environment of heavily modified and artificial water bodies. This issue is related to the implementation of the Water Framework Directive 2000/60/EC and the harmonization of the level of good ecological potential among EU Member States.

The aim is effectiveness assessment of the designed measures in the Litava basin in hydrological model created in software HEC-HMS (Hydrology Engineering center – Hydrologic modeling system).
Course of the weather in the last years shows that variability of the weather increases and this also leads to a higher frequency of floods, as well as drought. Drought, regardless of its type, means that there is a lack of water in landscape.
The impact of oxygen and nitrates availability on phosphorus cycle in sediments – an example of the Vranov Reservoir
The inflow parts of eutrophic reservoirs typically exhibit exacerbated rates of primary production, with concomitant increase in organic matter sedimentation. Its microbial remineralization leads to the consumption of electron acceptors.
The Czech Republic does not sufficiently create the necessary conditions for the conceptual approach to urban drainage based on the principles of a sustainable development. The Ministry of Agriculture of the Czech Republic, responsible for the water management, ignores how much a strict implementation of a sustainable drainage system, especially the blue-green infrastructure, could positively impact urbanized areas’ adaptation to climate change.
Interview with the Director of the Czech Hydrometeorological Institute Mgr. Mark Rieder on the subject of his long career in TGM WRI and his experience with water. What are his plans for the future?
Ohře is one of the rivers, which retained in part the original structure of the flow with the presence of shallower, more flowing sections with deeper pools and fountains. This is the reason why there are several protected animals in the Ohře, for which the well-known European locality (EVL) was declared on the river Ohře.

The oldest history of Peru is usually associated with the Inca Empire. It is true that during the reign of Inka Pachacuti, this was an empire that was unparalleled in the South American continent. When Pachacuti died in 1471, his empire was dragged over 3,800 km from Chile today to the south after Ecuador to the north, and partly to the territory of today’s Argentina, Brazil and Bolivia.
