Flash flood in Brdy PLA in June 2024

–

The article documents the course of the flash flood at the beginning of June 2024 in Brdy PLA, in the Příbram Region, including reflection on its causes and possibilities for limiting the consequences of this type of flood in the future. Publicly available information was evaluated from the hydrometeorological situation in the Archive of weekly reports on the CHMI website for the nearest station to the flood-affected area, namely Neumětely station. In that week, the highest weekly precipitation total for the Czech Republic was recorded at Neumětely station. When evaluating landscape development based on archival maps or orthophoto maps, changes with some negative effects on water retention in the landscape were observed. It was mainly the gradual expansion of urban development into the original mosaic of dry or wet meadows and small fields, straightening and piping of watercourses, ploughing their floodplains, land reclamation of spring areas, and their subsequent replacement with arable land.

Disappeared pond system in the lower Doubrava river

–

This article presents the results of research of the pond landscape development in the lower Doubrava river. The results are based on the interpretation of archival map documents and the current state of the site. On the map of the 1st military mapping (1764–1768), a system of thirteen ponds was recorded on the right bank of the Doubrava river. There were three ponds on the left bank of the Doubrava river. On the map of the 2nd military mapping (1836–1852), only four ponds were recorded on the right bank of the Doubrava river and only two ponds on the left bank of the Doubrava river. Of the historic pond system, only Koukalecký pond and a pond near Žehušice chateau have survived to the present day. On the 1st military mapping map, the total approximate area of the ponds was 449 ha, on the 2nd military mapping map it was 107 ha, and today only 0.91 ha.

Development of pond locations in the Polabí lowland since the mid-19th century – part 2 – Poděbrady region

–

This article presents the results of research on landscape changes in the Poděbrady region as part of the Polabí lowland, where there have been significant changes in the location of ponds. The area of all types of ponds (according to stability) makes up 3.17 % of the Poděbrady region. Ac-cording to their occurrence in the area in 1836/1852–2022, the ponds (or their parts) were divided into disappeared, continuous, and new. Disap-peared ponds have the largest representation – about 60 % of the total pond area according to stability. They are followed by continuous ponds, with the minimum area represented by new ponds. The historical or (more precisely) disappeared ponds were more robust than the present ones, i.e., they had a larger average size. Analyses show that almost three-quarters of the disappeared ponds have been replaced by arable land.

Development of pond locations in the Polabí lowland since the mid-19th century – part 1 – Pardubice region

–

This article focuses on mapping the development of the lowland landscape over the last 180 years, related to pressures to use lowland areas for economic purposes, including transformation of wetland habitats (specifically ponds) into arable land.  The Polabí lowland was chosen as the study area because it is currently affected by a lack of water and there is an occurrence of seasonal drying up of small watercourses. This issue will probably be of greater significance in the future, particularly in the context of the expected continued extreme climatic phenomena. Within the Polabí lowland, the results from the Pardubice region (where the biggest change in pond locations occur) are presented here. The area of all types of ponds (according to their stability) makes up 6.83 % of the study area. According to their occurrence from the Second Military Mapping (1836–1852) up to 2022, the ponds were divided into disappeared, continuous, and new. Disappeared ponds have the largest representation – about two-thirds of the total pond area according to stability. They are followed by continuous ponds, and the smallest area is represented by new ponds. The historical, or more precisely, disappeared ponds were more robust than the present ones, i.e., they had a larger average size. Analyses show that almost half of the disappeared ponds have been replaced by arable land.

Landscape changes in selected locations of the Polabí lowlands with a focus on wetlands

–

This article presents three typologically different sites from Polabí where large-scale wetland sites were located in the past, including ponds. These sites were chosen in order to present disappeared floodplain meadows, disappeared “field” wetlands, disappeared ponds or pond systems, and, simultaneously, to present sites where wetland habitats have been at least partially restored. The main aim was to present easily accessible archival maps, on the basis of which it is possible to assess the spatio-temporal dynamics of wetland habitats in the places of disappeared wetlands with regard to their possible restoration.

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.

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 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.
