Comparing various methods for determining the water footprint of electricity generation at Orlík hydroelectric power station – case study

A large part of the world’s population does not have access to quality water resources in sufficient quantities. Therefore, comprehensive methods for assessing water use have been developed in recent years. One is the water footprint, which allows expression of the total amount of water consumed to produce a product or service.

The First Czechoslovak Republic hydrobiological stations – The beginnings of scientific fish research in Moravia

Field stations represent one of the forms of fishery or fishpond research. Their origins can be found at the end of the 19th century, but this type of research program flourished during the interwar era. At that time, two of the oldest and most important hydrobiological stations in Moravia – Lednice (1922) and Velké Meziříčí (1928) – were established.

Determination of the extent of soil unprotected by vegetation in the period of rainstorms to assess erosion risk

The article describes the method, the source data, and the results of analyses of bare soil by remote sensing and its relation to soil erosion risk. The method was tested on the parcels of AGRA Řisuty, s. r. o. Data from the satellites Landsat 8 and Sentinel 2 were used for detecting the presence of vegetation cover on each parcel.

Possibilities of using old topographic maps from the years 1763–1768 for evaluating the development of water bodies and the potential for their renewal

Potential of water areas restoration is a hot topic in present landscape planning. The focus is usually on water areas from mid-19th century where their location is quite good due to maps’ positional accuracy. Yet, we can also use older Austrian military survey from 1763–1768, which enables us to locate dams of water areas and assess potential for restoration of these areas.

Pay it forward – Alias from which is the Průhonice Park producing biomass of cyanobacteria for the Hostivař water reservoir?

The UNESCO World Heritage Site – Průhonice Park is visited by hundreds of thousands of people annually. The view of the park ponds, however, has been immaculate in the past five years because it is covered by a continuous layer of cyanobacteria forming a water bloom.

How to learn the level of legal and technical principles for the application of blue infrastructure

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.

Principles of approach to optimization of water and soil protection in the Svratka River sub-basins

Presently a demand of sustainable maintenance of water quantity and quality is more and more accented in context of population booming and actual climate change. A research project no. QJ1620040, supported by the Czech Agricultural Research Agency, has started in 2016 with the aim to assess the options for reduction of water pollution both from point and non-point sources with suspended solids, nitrogen and phosphorus in drinking water sources catchments.

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

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.

Water quality in drinking water reservoir Švihov on Želivka river and its river basin, with focus on specific organic compounds

River basin of the largest drinking water reservoir Švihov on the Želivka River is distinctly anthropogenically affected both by direct human activities and also by the agriculture. The quality of the surface water is endangered in long-term period mainly by the eutrophication, pesticides pollution and erosion.

Assessment of the relationship between water quality and functions of small water reservoirs

Small water reservoirs are one of the principal elements of agricultural landscape in the Central European context. The monitoring of the quality of aquatic environment of selected ponds and small reservoirs (SWR) in areas of southern and central Moravia and the Vysočina Region was carried out in 2013 to 2015.

Risk assessment of drying up of small streams in the Czech Republic

A categorization of the Czech Republic territory in terms of the risk of drying up of small streams (1st to 4th order by Strahler) was proposed. Three levels of risk (low, medium and high) for basic hydrological units (catchment) were set. The risk levels were defined using selected abiotic characteristics of the hydrological units and their combinations.
