Abstract
  Weirs are installed on open channels to adjust and measure the flow. Also, discharge coefficient is considered as the most important hydraulic parameter of a weir. In this study, using the Radial Base Neural Networks (RBNN) and M5' methods, the discharge coefficient of triangular plan form weirs is modeled. ...  Read More

Research Paper
Optimizing ANFIS for sediment transport in open channels using different evolutionary algorithms

Sultan Noman Qasem; Isa Ebtehaj; Hossien Riahi Madavar

Volume 4, Issue 1 , June 2017, Pages 290-298

https://doi.org/10.22126/arww.2017.773

Abstract
  Flow through open channels can contain solids. The deposition of solids occasionally occurs due to insufficient flow velocity to transfer the solid particles, causing many problems with transfer systems. Therefore, a method to determine the limiting velocity (i.e. Fr) is required. In this paper, three ...  Read More

Mean flow characteristics, vertical structures and bed shear stress at open channel bifurcation

Akbar Safarzadeh; Babak Khaiatrostami

Volume 4, Issue 1 , June 2017, Pages 299-304

https://doi.org/10.22126/arww.2017.774

Abstract
  Water supply from rivers is accomplished with flow diversion through an intake structure. A lateral intake like bifurcation is the simplest method to withdraw water. However, flow at a channel bifurcation is turbulent, highly three-dimensional (3D) and so has many complex features. This paper reports ...  Read More

Investigating the capabilities of the NSGA-II multi-objective algorithm in automatic calibration of the WEAP model for simulating Jareh Dam and network system

Arash Azari; Milad Asadi

Volume 4, Issue 1 , June 2017, Pages 305-313

https://doi.org/10.22126/arww.2017.775

Abstract
  In the simulation models of water resource systems, calibration processes should be performed to approximate the simulated values to the observed values due to the errors in such models. However, due to being time consuming and the difficulties associated with manual calibration, an automatic calibration ...  Read More

Reverse osmosis design with IMS design software to produce drinking water in Bandar Abbas, Iran

Nafiseh Aghababaei

Volume 4, Issue 1 , June 2017, Pages 314-318

https://doi.org/10.22126/arww.2017.776

Abstract
  Reverse osmosis (RO) has proven to be an efficient technique for desalination of seawater, brackish water, and reclaimed wastewater. However, the performance of RO desalination is sensitive to its design parameters and operating conditions. The purpose of this study was to modeling the removal of total ...  Read More

Advanced oxidation processes treating of Tire Cord production plant effluent: A comparative study

Maryam Habibi; Ali Akbar Zinatizadeh; Mandana Akia

Volume 4, Issue 1 , June 2017, Pages 319-330

https://doi.org/10.22126/arww.2017.777

Abstract
  The degradation of an industrial wastewater (Tire Cord factory) with low BOD5/COD ratio (0.1-0.2) was investigated using advanced oxidation processes (AOPs) (i.e. hydrogen peroxide, UV/H2O2, O3/H2O2 and UV/O3/H2O2 treatments). In order to investigate the effects of influential variables on the process ...  Read More

Volume 4, Issue 1 , June 2017, Pages 331-333

https://doi.org/10.22126/arww.2017.779

Abstract
  Oil refinery wastewater as the most polluting industrial wastewater contain various hydrocarbons and sulfur with its derivatives and can cause problems in biological systems by the production of sulfuric acid. Variations of amount of sulfur depending on bioreactor condition such as temperature, pH, microbial ...  Read More
