Design optimization of concrete gravity dams using grasshopper optimization algorithm
Abbasi, Salim; Seifollahi, Mehran; Farzaneh, Shahin; Daneshfaraz, Rasoul; Süme, Veli; Sadraei, Naghi; Abraham, John (Springer, 2024)The efficiency and sustainability of dams can be significantly improved by structural optimization during the design process. This study aims to optimize geometric dimensions and minimize the concrete volume of three ... -
Experimental investigation and application of soft computing models for predicting flow energy loss in arc-shaped constrictions
Abbaszadeh, Hamidreza; Daneshfaraz, Rasoul; Süme, Veli; Abraham, John (IWA Publishing, 2024)This investigation focuses on flow energy, a crucial parameter in the design of water structures such as channels. The research endeavors to explore the relative energy loss (Delta E-AB/E-A) in a constricted flow path of ... -
Experimental study of the effect of non-structural materials on scouring of bridge piers with removal of river material: cationic polyacrylamide (PAM)
Daneshfaraz, Rasoul; Rezaie, Mehdi; Aminvash, Ehsan; Dasineh, Mehdi; Abraham, John; Süme, Veli (Springer, 2024)Scouring damage to piers is a major risk factor for hydraulic structures. In this research, a new eco-friendly method has been proposed to reduce both the length and depth of scouring near bridges and the volume of pits ... -
Investigation of clean energy production in drinking water networks
Süme, Veli; Daneshfaraz, Rasoul; Kerim, Ali; Abbaszadeh, Hamidreza; Abraham, John (Springer, 2024)Viable renewable energy sources must be low-cost, easy to install, clean, and reliable if they are to meet the energy demand of urban or rural areas. Water is able to provide efficient sources of electrical energy among ... -
On the effect of green nonstructural materials on scour reduction downstream of grid dissipators
Daneshfaraz, Rasoul; Rezaie, Mehdi; Aminvash, Ehsan; Süme, Veli; Abraham, John; Ghaderi, Amir (IWA Publishing, 2023)In this study, a nonstructural and eco-friendly solution has been used to reduce scouring downstream of screens. Upstream of the screen are stilling basins protected against scouring, but downstream locations are subjected ... -
Sill role effect on the flow characteristics (Experimental and Regression Model analytical)
Abbaszadeh, Hamidreza; Norouzi, Reza; Süme, Veli; Kuriqi, Alban; Daneshfaraz, Rasoul; Abraham, John (MDPI, 2023)This study investigates the effects of gate openings and different sill widths on the sluice gate’s energy dissipation and discharge coefficient (Cd). The physical model of the sills includes rectangular sills of different ...
