Hydraulic Structures in Urban Drainage Systems
Large hydraulic structures are of major importance to sustained life-support systems and have an impact on the environment. Dams, reservoirs and open canals are such structures, the impact of which has been duly appreciated and addressed in environmental impact assessments and side-effects amelioration programs. Less obvious, but of vital importance, is the impact of urban drainage systems on h...
متن کاملLocal surface aeration at hydraulic structures
In open channel flows, local surface aeration processes occur mainly at weirs and drop structures and in hydraulic jumps. Air entrainment in the wakes of bluff bodies is observed only in high speed flows. In water pollution abatement, the natural gas exchange at the free surface is sometimes not sufficient to balance the oxygen consumption due to pollutants. In such cases, local aeration is nee...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

متن کاملOptimal hydraulic structures profiles under uncertain seepage head
Most of the hydraulic structures are founded on permeable foundation. There is, however, no procedure to fix the basic barrage parameters, which are depth of sheet piles/cutoffs and the length and thickness of floor, in a cost-effective manner. Changes in hydrological and climatic factors may alter the design seepage head of the hydraulic structures. The variation in seepage head affects the do...
متن کاملCoherent structures in flow over hydraulic engineering surfaces
Wall-bounded turbulence manifests itself in a broad range of applications, not least in hydraulic systems. Here, we briefly review the significant advances over the past few decades in the fundamental study of wall turbulence over smooth and rough surfaces, with an emphasis on coherent structures and their role at high Reynolds numbers. We attempt to relate these findings to parallel efforts in...
