https://doi.org/10.22126/arww.2020.5269.1169

Abstract
  In the current study, a new hybrid of the genetic algorithm (GA) and adaptive Neuro-fuzzy inference system (ANFIS) was introduced to model the discharge coefficient (DC) of triangular weirs. The genetic algorithm was implemented for increasing the efficiency of ANFIS by adjusting membership functions ...  Read More

Mohammad Ali Izadbakhsh; Reza Hajiabadi

Volume 7, Issue 1 , June 2020, , Pages 1-13

https://doi.org/10.22126/arww.2020.4578.1146

Abstract
  In the article, through the adaptive neuro-fuzzy inference system (ANFIS), a sensitivity analysis is conducted on the variables affecting the discharge capacity of the weir. To this end, the variables affecting the discharge capacity of labyrinth weirs are initially identified. Then, using these input ...  Read More

Optimization of ANFIS model using wavelet transform for simulating groundwater level variations

Fariborz Yosefvand; Saeid Shabanlou

Volume 7, Issue 1 , June 2020, , Pages 23-29

https://doi.org/10.22126/arww.2020.4150.1123

Abstract
  In this study, for the first time, groundwater level (GWL) variations of the Sarab-e Qanbar well located in the city of Kermanshah, are simulated over a 13-year period by a hybrid model named WANFIS (wavelet-adaptive neuro fuzzy inference system). In order to develop the hybrid model, the wavelet transform ...  Read More

Prediction of the hydraulic jump length on sloping rough beds using meta- heuristic neuro-fuzzy model and differential evolution algorithm

Rahim Gerami Moghadam; Behrouz Yaghoubi; Mohammad Ali Izadbakhsh; Saeid Shabanlou

Volume 6, Issue 1 , January 2019, , Pages 8-15

https://doi.org/10.22126/arww.2019.1019

Abstract
  Generally, Hydraulic jumps usually happen at the downstream of hydraulic structures like ogee spillways. In addition, one of the parameters affecting the proper design of stilling basin is calculation of the hydraulic jump length. In this study, a hybrid method (ANFIS-DE) was proposed for modeling hydraulic ...  Read More

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
