Analysis of hydraulic conditions in steep river channel on the case of Hotoveljscica torrent

Abstract

Extensive areas of steep slopes and uneven distribution of precipitation in Slovenia result in\ud a great number of watercourses which have torrential characteristics. That is why we are on\ud a daily basis encountering and trying to deal with problems which torrents are bringing into\ud built environment. Computer programs used for modeling of watercourses are based on\ud standard equations for analysing hydraulic conditions in lowland watercourses; they might\ud not give correct results in steep torriental watercourses. This graduation thesis focuses on\ud the issue of hydraulics of steep stream channels and the limitations when using classic\ud hydraulic equations and mathematical hydraulic models, such as Hec-Ras. In the practical\ud part, a specific section of the Hotoveljščica torrent is examined in terms of river-bed and\ud hydraulic conditions additionaly, erosion processes are analyzed. An outline plan for flood\ud protection measures ate the analyzed section of the Hotoveljščica torrent is proposed
