Aktualizace rozvodnic základních ploch povodí 4. řádu

Abstract

The 5th generation of digital model relief (DMR 5G) and water courses of the state ZABAGED© geographic database were the necessary, but not the only basis for the update of basic watersheds, which were done in the ČHMÚ in the years 2018–2022. During the update, data of sewage network in Prague, foreign drainage divides of neighbouring countries or the results of the Harmonization of main watercourses project were used. The article also describes the historical development of the watersheds and the juristic background of the whole issue.
