Hydraulic Resistance of Corrugated Metal Culvert Pipes with Elevated Abrasive Resistance

Resumo

The paper puts forwards some results of studies on hydraulic resistance in a corrugated metal pipe with helical corrugation and smooth invert trough. Recommendations are given for calculating the roughness coefficient for pressure or free-surface water flows. Results of hydraulic studies suggest that pipe filling and slope impacts hydraulic resistance in free-surface flows.
