The main goal of our thesis is a lexicographic processing of names of watercourses in the Upper Lužnice (Ober Lainsitz) river basin. Due to its location on the borders of Czech and German speaking territories and gaps in Czech methodological approaches our thesis is based on sophisticated theories of German hydronomastics that reflect common etymological roots of European water names as well as of the Slovak ones that strive for modern international processing of hydronyms complying with uniformed, obligatory methodology of the lexicographic project Hydronymia Europaea. Water names that were excerpted mainly from archival and contemporary maps have undertaken semantic classification invented by V. Šmilauer and M. Frydrich regardless of the source language. Along with the verification of suitability of the foreign methodology adopted for Czech hydronyms the thesis makes partial advice on its innovation that could help make the using of the lexicon more user friendly.

This diploma thesis extends the bachelor thesis research that analysed selected anoikonyms which were used by the locals since the oldest times until the beginning of the 19th century. The goal of this thesis is to revise and complete the set of anoikonyms included in the bachelor thesis and compare it to younger evidences. By collecting the data and its formal and semantic analysis the thesis aims to present a relatively complete picture of anoikonyms of the area of interest while respecting its historical development.
