Pointe Coupee Pumping Station Siphon, Upper Pointe Coupee Loop Area, Louisiana; Hydraulic Model Investigation.

Abstract

Hydraulic models were used to evaluate the hydraulic performance of the Pointe Coupee pumping station siphon. A trap design was developed to ensure maintenance of the priming seal and to prevent excessive negative pressures at the siphon crown. The diameter of the siphon was reduced to obtain adequate priming velocities. Use of deflectors to induce priming was also tested. Pressure fluctuations and head losses were measured in the model. Scale effects inherent to siphon modeling are discussed. The recommended design siphon operated satisfactorily for the entire range of expected tailwaters and discharges.
