Determination of basic typology of elevated water tanks

This paper introduces an initial effort at a systematic approach to the typology of elevated water tanks for the purpose of solving the research project Elevated water tanks – identification, documentation, presentation, new use. It builds on the previous definition of the terminology of the problem and the definition of the object of interest. From a typological point of view, elevated water tanks are seen as an integral part of larger technological units – water supply systems. In the framework of the basic division, the typology of elevated water tanks is based on the selection of parameters – the building situation of the tower reservoirs in relation to other objects, the function of elevated water tanks, the supporting structure, the shape and material of the accumulation tank, the number of tanks and the purpose of the object.

Water quality of the Prague’s streams. Part 1: Motolský and Litovický streams

Results of water quality observation in the selected profiles on the Motolský and Litovický streams during the year 2018 are presented. Monitoring of water quality parameters was focused mainly on the nutrients content (nitrogen and phosphorus), chlorophyll-a concentrations and on the phytoplankton and zooplankton species composition.

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.

Assessment of changes of long-term flow characteristics for the period 2001–2015 over the reference period 1961–2000 in selected Slovak gauging stations

The period 2000 to 2015 is a period in which we have observed significant differences and extremes in the hydrological regime of Slovak flows. The Slovak Hydrometeorological Institute, in the framework of its tasks, processes a comprehensive assessment of hydrological characteristics focused on drought assessment.

Joint Danube Survey 4 – the biggest international river expedition of the year is coming soon

In June 2019 on the Danube Day will start the biggest international river expedition of the year Joint Danube Survey 4 (JDS4). Joint Danube Surveys are organised by Secretariat of the the International Commission for the Protection of the Danube River (ICPDR) Three Joint Danube Surveys were previously conducted in 2001, 2007, and 2013.

Climate change in dryas and at the beginning of the Holocene – rise in ocean levels and its impact on the migration of civilizations in the Middle East and the Indian Ocean

Today’s history or archeology is nowadays a highly developed field that that has long since surpassed during the twentieth century, its original, rather humanities, focus – at a deeper acquaintance with a number of published articles or monographs, however, you can find a deficit in relation to the relatively recent findings from climate change history.
