The Location and Extent of Systematic Drainage in Relation to Land Use in the Past and at Present and in Relation to Soil Vulnerability to Accelerater Infiltration in the Protected Landscape Area Železné Hory

Abstract

This study searched for associations between the extent of hydromelioration systems and the land use (in the past and at present), degree of nature conservation, and infi ltration of water through soil profi le in the Protected Landscape Area (PLA) Železné hory. According to the available evidence, 34.6% of arable land and 32.1% of permanent grasslands in this area are drained by the drainage systems. Analysis of the original design documentations of drainage structures indicate, that the extent of drained areas can actually be even higher. The hydromelioration systems were built namely in the second half of the 20 th century. The drainage also aff ected alluvial meadows, wetlands, and ecologically valuable stations. A er establishment of PLA Železné hory in 1991, the protected area was divided into four zones according to their signifi cance and protection regime. This study has revealed the presence of areas drained by systematic drainage systems (101 ha of grasslands) even in the zones of highest landscape protection degree (1 st and 2 nd protection zones). The inadequately executed drainage systems should be eliminated and the character of the land should be brought closer to its natural conditions. On the model part of the PLA we also performed a study of historical changes in the landscape in three time horizons (1839, 1950, 2014) to show diff erences in land use before building of drainage, at the time of building, and at present.

Franziscean Cadastre in Landscape Structure Research: A Systematic Review

“…Studies focused on agricultural land (n=17) elaborated the losses or localization of individual subcategories of agricultural LULC classes such as vineyards (Žiberna 2015), arable land (Szturc et al 2017) or meadows and pastures. Special attention was given to the development/ reconstruction of agroforestry classes (Forejt et al 2017, Krčmářová, Jeleček 2017 or water retention of the landscape based on the agricultural land use development (Karásek et al 2015). The special subcategory focused on the social metabolism and flows of material and energy (Krausmann 2008, Fraňková, Cattaneo 2018.…”

“…ha) (Kulhavý et al, 2007). Drainage and fertilization were frequently applied in unsuitable localities, resulting in profound changes in the landscape (Langhammer et al, 2008;Karásek et al, 2015). Both the drainage and land degradation due to water and wind erosion negatively impact the water retention in the landscape.…”

The accuracy of drainage network delineation as a function of environmental factors: A case study in Central and Northern Sweden

“…Thus, it is impossible to assess the quality of a delineated drainage network at a local scale, in specific portions of a catchment, and this shortcoming substantially limits the ability to communicate detailed information about the data quality of a delineated drainage network to its users (Johnston & Timlin, 2000). This will further cause problems for water resources management, for example, irrigation system design in farming planning (Bhattacharya & Michael, 2006; Karásek, Tlapáková, & Podhrázská, 2015; Molle et al, 2007; Young, Smart, & Harding, 2004).…”
