Abstract

The purpose of this paper is to present the experiences gained during conducted field measurements on a culvert in Hungary, as well as the hydraulic computation of this structure. The measurements were performed on a culvert with a pipe arch cross-section, which is located on a cutoff meander on the Danube near the town of Baja. During the field measurements velocity distributions and water surface elevations were determined, along with other parameters necessary for establishing a dependency between discharge and water elevation. For the hydraulic computation the HY-8 software was used, which is based on equations published by an USA agency (Federal Highway Administration). The analysis of measured and computed values yielded the conclusion that the software's results are in good agreement with the measured values. Hence, the usage of this software is recommended for hydraulic computation of pipe culverts.
