This article presents the first results of the research focused on the recording of rill erosion, and its evaluation using the outputs of the two methods that can be used to determine the soil yield. The consequences of erosion have been documented on a selected pilot site, both as a direct method of volume quantification (using an profile meter – so called soil erosion bridge) and with the use of unmanned aircraft in close-up photogrammetry (UAV).

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.
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.
The Nitrate Directive defines rules for a delimitation of vulnerable zones and sets out tools to reduce nitrate pollution. The fundamental instrument is the Action Program and the Good Agricultural Practices [1].
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.
As part of the Drought project, a comprehensive monitoring of watercourses and land in their catchment areas was launched in the Czech Republic to assess the impact of the implementation of revitalization actions to protect against the effects of drought.
These and other questions were answered by experts who come into contact with drought and water shortages daily.

TGM Water Research Institute, p. r. i., the Czech Nature Protection Agency, the Czech Fishing Union Council, the Czech Fisheries Union Council, and the local organization of the Czech Fishing Union Lysá n. Labem (MO ČRS Lysá n. Labem) together with the Expert Group – The Commission for Fish Transfers at the AOPK Czech Republic organized a second year of the World Fish Migration Day (WFMD), Fish Education Day for children, youth and the general public with the title “Where do the fish go?”
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.
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.
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.

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 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.
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.
