Pressure Driven Analysis (PDA) method provides the ability to simulate Water Distribution Networks (WDNs) more realistically. Most of the PDA-based models use either the Newton–Raphson method or the gradient method for simulation. The computational cost of these models is high, so that in the...
Management and planning of water resources in drainage basins have always been among the most challenging issues in water industry in Iran. Shortage in water resources, increasing agricultural productions and providing nutrition health are the concerns of the governments in guaranteeing...
To optimize the layout of a sewer network, first, the feasible layouts of the network are generated and then the best layout design is identified from among the numerous possible configurations subject to constraints. For this purpose, a Hybrid Genetic Algorithm (HGA) is developed here. This...
In this paper, in order to investigate the effects of abutments in presence of a pier on scour depth and bed topography alteration, a series of tests were carried out considering abutments with a length twice that of the pier and vertical and inclined piers with their inclination towards...
Deep-Sea Tailings Placement (DSTP) systems have been used at several mines to discharge diluted mine tailings at great depths. DSTP often provides considerable environmental and engineering benefits compared to traditional on-land tailings storage. The key element in the viability of a DSTP...
The optimum dose for cement kiln dust (CKD), lime, Ferric chloride, alum required 60, 40, 40, 60 mg/L to bring down the turbidity of grey water from 29.3 to 3 NTU. Ferric chloride and Lime reduced the grey water COD 50 mg/L at 40–60 mg/L of dose. The aerobic migrating column reactor (AMCR)...
