Kombination von wasserbaulichem Modellversuch mit numerischer Strömungsberechnung gezeigt am Beispiel des BHQ-Abflusses im Stauraum des Kraftwerks Ashta 1

Abstract

Combining hydraulic model tests with numerical flow analysis: The design flood for the reservoir above the Ashta 1 power station in Albania Summary: This article describes hydraulic scale model tests and compares the results with those obtained from a numerical simulation of the design flood (5,900 m³/s corresponding to an estimated 500-year event) for the reservoir of the planned Ashta 1 Hydromatrix power development in Albania. The investigation led by Pöyry Energy, included a 2d analysis of this extreme event. Considering the substantial effect the calculated results will have on further planning and design as well as the importance of the flood water levels for a neighbouring residential area and a main traffic connection, a contract was awarded to the Institute of Hydraulic and Water Resources Engineering at the Vienna University of Technology for performing hydraulic scale model tests as a basis for these numerical analyses and for checking the results. This article presents the results of the two independently-conducted studies. Einleitung 1.
