Volume 4, Issue 2 , December 2017, Pages 358-362

https://doi.org/10.22126/arww.2017.792

Abstract
  Electronic weather stations have increased the availability of weather data for computing hourly and daily reference evapotranspiration (ETo). There is a rational question applied for different climate conditions whether the sum of hourly ETo computation may differ from direct computed daily ETo. In ...  Read More

Research Paper
Numerical simulation of prevention of saltwater intrusion in panama channel by using of bubble curtain system

Mehdi Nezhad Naderi; Omid Zolfaghari

Volume 4, Issue 2 , December 2017, Pages 363-369

https://doi.org/10.22126/arww.2017.800

Abstract
  A bubble curtain is a system that produces bubbles in a deliberate arrangement inwater. The technique is based on bubbles of air (gas) being let out under thewater surface, commonly on the bottom. When the bubbles rise they act as abarrier, a curtain for prevention of the spreading of particles and othercontaminants. ...  Read More

Kinetic study of biohydrogen production by anaerobic fermentation in a modified UASB-FF reactor

Parviz Mohammadi; Shaliza Ibrahim; Mohamad Suffian Mohamad Annuar

Volume 4, Issue 2 , December 2017, Pages 370-372

https://doi.org/10.22126/arww.2017.809

Abstract
  Fermentative hydrogen production is a common anoxic process where the bacteria degrade organic matters to produce the required electron in the anaerobic reaction. Dark fermentation in the acidogenic phase utilizing obligated and facultative anaerobes leads to hydrogen (H2) production. This method usually ...  Read More
