Comparison GIS-Based interpolation methods for mapping groundwater quality in the state of Qatar
( Elsevier B.V. , 2021 , Article)Groundwater (GW) quality deterioration is one of the main water security issues in Qatar. GW in Qatar is over-exploited for agriculture activities that caused saltwater intrusion in the coastal areas and some inland GW. ... -
Comparison of 1D and 3D heat and mass transfer models of a counter flow dew point evaporative cooling system: Numerical and experimental studyÉtude comparative numérique et expérimentale de modèles de transfert de chaleur et de masse 1D et 3D d’un système de refroidissement évaporatif à point de rosée à contre-courant
( Elsevier Ltd , 2019 , Article)In this study, the performance of a counter flow dew point evaporative cooling system has been examined, numerically and experimentally. A one-dimensional (1D) model of the heat and mass transfer in the cooling system is ... -
Comparison of 2D triangular C-grid shallow water models
( Elsevier Ltd , 2018 , Article)An ideal two-dimensional (2D) shallow water model should be able to simulate correctly various types of waves including pure gravity and inertia-gravity waves. In this paper, two different triangular C-grid methods are ... -
