Our laboratory is 140 m long and 40 m wide and has thus a working area of 5600 m². 30% of the area is occupied by permanent installations for basic research (e.g., hydraulic flumes, wave channels, harbour basin, etc.). The other 70% of the area are used for physical scale models related to practical hydraulic engineering problems (weirs, sluices, spillways, dams, rivers, harbours, navigation channels, etc.). The laboratory is equipped with a closed water circuit for which an underground water tank serves as reservoir. From this tank the water is pumped to a high level tank (10 m head) and distributed to the flumes and scale models via a pipe system.
