An aqueduct structure is a complex structure as compared to bridge, as it takes canal water across stream and canal traffic over the trough. The water-tightness and free expansions - contractions of trough, canal water load as well as traffic load on the trough involves complex load combinations, for which the superstructure and substructure of it is required to be planned and designed. The object of this research paper is to develop an optimized hydraulic design, by integration of various theories applicable, to provide cost effective aqueduct structure. This integrated hydraulic design for an aqueduct trough aims at minimization of water-way area of moving water, thus, minimizing mass of moving water per unit length of an aqueduct trough, which will result into lesser water load on aqueduct trough which ensures less quantity of construction materials and thus the aqueduct substructure and superstructure is economical. A case study of the executed project is also depicted which shows around 29% saving in concrete quantity by this method.
Key words: Aqueduct, trough, total energy line (TEL), head loss (HL), Integrated hydraulic design.
