Research ArticleOpen accessIn the abstractFINITE VOLUME METHOD OF MODELLING TRANSIENT GROUNDWATER FLOWN. Muyinda, G. Kakuba, J. M. MangoIn the field of computational fluid dynamics, the finite volume method is dominant over other numerical techniques like the finite difference and finite element methods because the underlying physical quantities are conserved at the discrete level. In the present study, the finite volume method is used to solve an isotropic transient groundwater flow model to obtain hydraulic heads and flow … …Journal of Mathematics and Statistics, Vol. 10, Issue 1 · 15 Feb 2014 · 7,111 accessesView PDFCite

Research ArticleOpen accessIn the abstractROLE OF SALINITY IN PRECIPITATION AND WELL WATER DEPTH RELATIONSHIPManoj K. JhaExcessive groundwater pumping can decrease the amount of fresh water flowing towards the coastal discharge areas, allowing salt water to be drawn into the fresh water zones of coastal aquifers. This process gets complicated with the frequent change behavior of groundwater levels in observation wells. The fluctuation happens due to various reasons but can be directly correlated with the precipitation … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 27 Mar 2014 · 7,957 accessesView PDFCite
