Utilization of artificial aquifer physical model to aid technical learning of groundwater hydrology

A study of hydrogeological process involves movement of water beneath the ground surface. Water content in the aquifer influences the quantitative determination of aquifer hydraulic parameters. The limited opportunity to explore and demonstrate groundwater processes is the reason why students have...

Well performance measurement provided by a step drawdown pumping test estimated the efficiency of well as 99%. The artificial aquifer model was verified by constant rate discharge pumping test and found to be a leaky aquifer. The pumping test analyzed the aquifer with transmissivity of 78.50m2/day and hydraulic conductivity of 7.37m/day while recovery test analyzed the transmissivity to be 8.22m2/day and hydraulic conductivity of 7.34m/day. Both test analyzed the storage coefficient as 0.5. This artificial aquifer physical model was designed and developed to enhance student‟s understanding of groundwater theory. Through hands-on pumping test on the aquifer model, students would be able to visualize clearer the groundwater processes.
