| Abstract | This work investgates the discharge capacity of a side conveyance structure located at lock No. 3 in the Dessel‐ Schoten canal. A frst level of analysis involves the use of classical semi‐empirical techniques available from hydraulics. A second level of analysis involves the use of Computatonal Fluid Dynamics (CFD), in an efort to reduce the uncertaintes associated with the use of the aforementoned techniques. It is shown that, although in principle the fow present in the side drainage falls into one of the categories in which the proposed tech‐ niques are valid, discrepancies with the results obtained numerically suggest that the underlying assumptons in the technique need to be revised when used for cases with similar characteristcs. This work also focus in reducing the impact of side fows for navigaton through locks, associated with the operaton of the side drain‐ age structure. Diferent alternatves for safe navigaton are proposed, and studied using CFD. In partcular, four scenarios are studied, of which three comprise diferent improvements to the original structure. One of the proposals is found to have promising features, whilst being relatvely simple. |
