At present, the inflow passes downwards via a horizontal screen into the specially shaped concrete spiral. To save construction depth, the unconventional spiral was designed in accordance with the idea of a pump intake sump. In the event of a flood, the weir installed above the turbine downstream of the screen can release additional water to the tailwater. … Authors ------- **Helmut Benigni**, Vice-head of the Institute of Hydraulic Fluid Machinery, Graz University of Technology **Jürgen Schiffer**, Managing Director of Prof. Dr. Jaberg & Partner GmbH **Gerhart Penninger**, Head of the Department for Mechanical Engineering and Hydraulic Steelwork, Verbund Hydro Power GmbH **Hannes Badura**, Hydraulic Engineer and Project Manager at Verbund Hydro Power GmbH **Christian Witti**, Lead Engineer Kaplan and Project Engineer for Stegenwald, Global Hydro Energy GmbH **Markus Pühringer**, Hydraulic Design and Power Plant Project Planning, Global Hydro Energy GmbH ![](https://www.jabergundpartner.com/fileadmin/_processed_/5/7/csm_pager_hpp_stegenwald_3821cada44.webp) [☛ Download here free of charge](https://www.jabergundpartner.com/fileadmin/user_upload/jabergundpartner/dateien_download/fachbeitraege_papers/HPP_Stegenwald_classical_vertical_kaplan_horizontal_arrangement.pdf) Our [privacy policy](https://www.jabergundpartner.com/en/cookies-privacy/) applies to this. --- ![](https://www.jabergundpartner.com/fileadmin/_processed_/9/5/csm_slider_newsletter_anmeldung_rabatt_pk_2020_2b3bff73ed.webp) Subscribe and benefit --------------------- Stay informed about our - conferences - continuing education programmes - activities [Subscribe Newsletter](https://www.jabergundpartner.com/en/landingpages/newsletter-registration-website-jaberg-partner/) You are here: - [Home](https://www.jabergundpartner.com/en/ "Home") - [News](https://www.jabergundpartner.com/en/news/news-and-activities/ "News") - [News and Activities](https://www.jabergundpartner.com/en/news/news-and-activities/ "News and Activities") - [LinkedIn](https://www.linkedin.com/company/prof-dr-jaberg-und-partner-gmbh "LinkedIn") - [Xing](https://www.xing.com/pages/prof-dr-jabergundpartnergmbh "Xing") [ ![](https://www.jabergundpartner.com/fileadmin/images/footerlogo.png)](https://www.jabergundpartner.com/en/) Prof.Dr.Jaberg & Partner GmbH Engineering & Consulting Kerscheckstraße 41 8076 Vasoldsberg Austria Contact - T [+43 (0) 316 393188](tel:+43316393188) - [info@![](data:image/gif;base64,R0lGODlhAQABAIAAAP///wAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw==)jabergundpartner.com](#) - [www.jabergundpartner.com](https://www.jabergundpartner.com) Service links - [ Sitemap ](https://www.jabergundpartner.com/en/sitemap/ "Sitemap") - [ Career ](https://www.jabergundpartner.com/en/about-us/career/ "Career") - [ Academy ](https://www.jabergundpartner.com/en/academy/ "Academy") - [ Imprint ](https://www.jabergundpartner.com/en/imprint/ "Imprint") - [ Cookies & Privacy ](https://www.jabergundpartner.com/en/cookies-privacy/ "Cookies & Privacy") - - [DE](https://www.jabergundpartner.com/de/news/aktivitaeten/salzachkraftwerk-stegenwald/kraftwerk-stegenwald-kaplan-turbine-in-horizontaler-lage/kraftwerk-stegenwald-fachbeitrag/ "Deutsch") - [EN](https://www.jabergundpartner.com/en/news/news-and-activities/technical-paper-for-journal-hydropower-dams/runner-optimisation-for-climate-related-changes-download-2-1/ "English") [by bluechip.at](https://www.bluechip.at "by bluechip.at")
