Using modern analytical methods for risk management and the creation of territorial strategies

and –

Social-economic and safety risks in area are one of the main topics in these days, which in the long term affect the stability of local societies. For identification of these risks, we can use modern technology of data collection based on the analysis of illicit substances in city wastewater, as the cities are a high-risk areas from the social perspective in the Czech Republic.

Water recreation in Prague from history to the present days

, , , , and –

Náhled do historie ukázal, že rekreace u vody, jako záliba k trávení volného času, byla odedávna rozšířena i v Praze, kde byly velmi oblíbené, dnes již zaniklé, říční plovárny. Na historický průzkum navázal v projektu „Možnosti vodní rekreace na území hlavního města Prahy (od historie po současnost)“ zcela aktuální průzkum potenciálních možností rozšíření míst ke koupání a rekreace u vody na území Prahy.

, and –

Článek shrnuje výsledky sledování kvality vody ve vybraných profilech Motolského a Litovického potoka, které probíhalo v roce 2018. Sledování bylo zaměřeno na změny obsahu živin (formy dusíku a fosforu), koncentrace chlorofylu-a a na kvalitativní složení společenstva fytoplanktonu a zooplanktonu.

Water quality and the assessment of anthropogenic pollution of the Elbe River oxbow lake sediments

and –

Tato práce je zaměřena na zhodnocení kvality vody a antropogenního znečištění sedimentů ve starých ramenech Kozelská tůň a Vrť středního toku Labe. Stará říční ramena jsou významnými ekosystémy, ve kterých se může ukládat velké množství znečištěného materiálu. Tato kontaminace může pocházet z průmyslových zdrojů znečištění především z 2. pol. 20. století.

Impact of fishponds on water quality of the Jordán water reservoir in Tábor

, , and –

Míra eutrofizace vodní nádrže Jordán v Táboře dosáhla na přelomu milénia velmi vysoké úrovně. To významně omezilo její vodárenské i rekreační využití. V letech 2011–2014 proběhlo na nádrži poměrně rozsáhlé odbahnění, v jehož průběhu bylo odstraněno téměř 270 tis. m3 sedimentů.

The assessment of the status of surface water bodies in the Czech Republic for the period 2013–2015

, , , and –

This article aims to present to the general public the results of the assessment of the ecological status/potential and chemical status of surface water bodies categories “river“ and “lake“ for the period 2013 to 2015 in the Czech Republic. The assessment was carried out in 2017 by the Water Research Institute of T. G. Masaryk, p. r. i.

Environment quality of water elements of heritage protected areas

, , , , and –

Water elements represent a significant part of the environment of cultural heritage sites, conservation zones and areas. To fulfil the required functions, which may include social, historical, recreational and educational, but also environmental functions; it is necessary to ensure their corresponding target state.

The impact of oxygen and nitrates availability on phosphorus cycle in sediments – an example of the Vranov Reservoir

, , , , and –

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.

Information about ORAM

–

Odra River Alarm Modul (ORAM) will be part of the NAVAROSO project. There are no results of tracer studies of the Czech part of the Odra River in the last twenty years. That´s the reason, why tracer experiment data of the Svitava River were used for analysis.

Municipal wastewater as a diagnostic medium

–

The paper outlines the possibilities of using the epidemiological approach to the analysis of municipal wastewater to monitor the lifestyle of the population, its dietary habits, the environmental impacts on humans, the assessment of the state of health of the population and monitoring the consumption of illicit drugs and other substances in the monitored population

Classification of surface water quality

, , and –

This article deals with new Czech Standard 75 7221 Water quality – Classification of surface water quality [1] and replaces the previous 19 years old standard [2]. It was necessary to take into account actual demands of the surface water protection from two points of view: pollution indicator selection and current environmental quality standards. The range of pollution indicators and limit values of water classification were revised.

Development of selected radionuclides in surface water in the vicinity of the Temelín Nuclear Power Plant in the period 1990–2016

, , and –

The paper presents results and interpretation of long-term monitoring of occurrence and behaviour of radioisotopes 3H, 90Sr and 137Cs in surface water in the vicinity of the Temelín Nuclear Power Plant. 3H, 90Sr and 137Cs originate predominantly from residual contamination due to atmospheric nuclear weapons tests and the Chernobyl disaster in the last century.

The importance of catchment characteristics in terms of intensive erosion runoff formation threat level

, , and –

We located almost 130 000 critical localities near to urban areas where eroded material can enter the urban area. These localities were divided into five threat categories. Detailed modelling by WaTEM/SEDEM provided an extensive database of almost 130 000 micro catchments with outlet profiles threatened by intensive erosion runoff, and classified by five categories of threat for infrastructure damages.
