The article presents the results of pilot hydraulic studies of the models of culvert facilities from steel corrugated structures (MCS) with normal (MCP) and a coil-wound (CMCP) corrugations of different sizes at their transient operational states (semi- and partial-pressure heads) with various bottom designs (without a flume at the bottom, a smooth flume, and gravel dumping). Influence of vortex funnel arising upstream of the MCPand CMCP under the extreme conditions of floods or significantly high water levels on the operational stability of the culvert junction in the partial-pressure head mode is studied. Recommendations have been made regarding establishing the length of the terminal free-flow section in the partial-pressure head mode of operation of the MCP and CMCP of various modifications and calculating their throughput capacity.
