Volume 9, Issue 1 , January 2022, Pages 16-22

http://dx.doi.org/10.22126/arww.2020.4916.1156

Abstract
  In this paper, the flow in the vicinity of rectangular side orifices placed in main channels is estimated by means of the FLOW-3D model. To reconstruct the flow free surface, the volume of fluid (VOF) approach is utilized. In addition, the standard k-ε and RNG k-ε turbulence models are ...  Read More

Hargreaves-Samani method: Estimation of historical annual, seasonal, and monthly Reference Evapotranspiration (ETo) in Dadu District, Pakistan

Shoukat Ali Shah

Volume 9, Issue 1 , January 2022, Pages 30-39

http://dx.doi.org/10.22126/arww.2022.7533.1237

Abstract
  Reference Evapotranspiration (ETo) counted as the main factor for assessing the amount of water, needed for crops as well as for the planning of water resources management. Several techniques, methods, and equations have been used for computing ETo. Thus, required weather data sets are the main challenge ...  Read More
