A scale model of part of the inlet culvert construction of Doelpolder was available after project 15_073 (Scale 
model test on combined in- and outflow construction of Doelpolder). Additional flume tests were done with 
this scale model in four different setups: without weir logs and without a trash screen, with weir logs and 
without a trash screen, without weir logs and with a trash screen, and with weir logs and with a trash screen. 
For eight different sets of fixed water levels before and after the culverts the discharge for each setup was 
measured. These measured discharges are then compared with calculated discharge, based on the same 
water levels and construction parameters with a set of discharge through a culvert formulations built in the 
code of TELEMAC. The calculated discharge are in good agreement with the measured ones. This shows that 
the culvert formulas present in TELEMAC are capable of reproducing the discharges through the complex 
culvert structures of the Flemish flood control areas.
