Excessive abstraction of freshwater at coastal regions may reverse the direction of flow of mass flux of dissolved salts (J) leading to Saltwater Intrusion (SI) contaminating freshwater in coastal aquifers. This work investigated the impact of seepage velocities and hydraulic gradients of various porous media on mass flux of saltwater contaminant. Darcy’s and Fick’s laws were used to develop a model which gives J as a function of seepage velocity (V) and hydraulic gradient i. In validating the model, an experiment was designed to determine J in which river bed sand were washed, dried and sieved into five different grain sizes of samples  using electric sieve with mesh ranged. The Ø of each sample was determined using v... view more»
