The analysis of agricultural landscape development shown on selected cadastral districts in the upper part of the Výrovka River basin

V tomto článku jsou ve vybraných katastrálních územích s převažující plochou zemědělské půdy porovnávány aktuální land use a struktura krajiny s historickým stavem z podkladů Císařských povinných otisků stabilního katastru. Jsou zde nastíněny možnosti využití analýz historického vývoje krajiny ke krajinné obnově v zemědělských oblastech, zejména s ohledem na obnovu mokřadních ekosystémů a revitalizaci vodních toků.

The Výrovka river basin as a suitable area for monitoring and comparing hydrological and landscape characteristics

The Výrovka river basin, as a compact area covering 542.5 km2, is very suitable for monitoring hydrological characteristics and comparing them in different landscape types. It is located on the border of the Lower Vltava and Upper and Middle Elbe sub-basins, extending in a range of 175–555 m above sea level, with a total of six landscape types according to the typology of the contemporary landscape of the Czech Republic. Simultane-ously, there is a varied mosaic in terms of geological subsoil and soil types. There have also been major changes in land use in this basin, mainly due to intensive agricultural activity and related watercourse modifications and amelioration. Monitoring activities within the project SS02030027 ”Water systems and water management in the Czech Republic in conditions of climate change” are currently taking place in the Výrovka river basin.

Monitoring changes in the landscape development on the northeastern edge of the Hřebeny Mountains with a focus on wetlands

This article deals with changes in wetlands on the north-eastern edge of Hřebeny Mountains in the last 180 years. It assesses the dynamics of these landscape elements in space and time. The cadastral areas of Čisovice, Řitka, Kytín, and Nová Ves pod Pleší were selected, with a total area of 3,785.57 ha. Analysis was carried out on the basis of the Imperial obligatory prints of the maps of the stable cadastre from 1840, an orthophotomap, and field research from 2020; it distinguished wetlands in the monitored area into continuous, extinct and new. The background data were processed in ArcGIS software, version 10.7.1. The area of wetlands decreased from 289.34 ha in 1840 (7.6% of the monitored area) to 39.26 ha in 2020 (1.04% of the monitored area). Based on the study of available data, three types of wetland habitats were classified: wet meadows, wet meadows with woody plants, and ponds.

Problematics of archive map data interpretation, specifically the wetland habitats

The article presents available on-line archive maps from the websites of the Archive of the Surveying Office and the Geoinformatics Laboratory of the J. E. Purkyně University, that provide an overview of the historical wetland habi-
tats location. The main research question is to find out the potential use of historical maps for the identification of the historical wetlands in the Czech Republic and the evaluation of various interpretations of wetland habitats based on these sources. Examples of wetlands on historical map data in the upper part of the Výrovka River basin are presented.

Surface Water Status Assessment for the Third Cycle River Basin Management Plan of the Czech Republic

The aim of this article is to acquaint the professional public with the summary results of the assessment of chemical status and ecological status/potential of surface water bodies “river” and “lake” categories in the Czech Republic for 2016–2018.
This assessment is one from the basis for preparation of the Third River Basin Management Plan (2021–2027) at all its levels: sub-basin plans, national plans, and international plans of the Elbe, Danube, and Oder river basin districts.

The trajectory of wetlands development in the upper part of the Výrovka river basin over the last 180 years

The article is focused on analysis of the change of wetlands coverage and the representation of various types of wetlands in the upper part of the Výrovka river basin over the last 180 years. The historical maps of the Stable Cadastre, current orthophotographs and GIS layers of actual localization and classification of different types of land cover were used as data sources.

Wetlands on historical maps

This article presents easily accessible archive maps that provide an overview of the historical location of wetlands and they are also suitable for GIS analysis.

Water Management Fifty

The TGM Water Research Institute, p.r.i., took part in the organization of the 46th Water Management Fifty on the occasion of the celebration of its 100-year existence. In addition to the classic choice between bikes and buckets, this year participants could also take a ride on a scooter for the first time.

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

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.
