Development of a Saltwater Intrusion Software Using Visual Basic

Coastal aquifers play important roles for sources of water. With growing concern on groundwater resources both in term of quantity and quality, proper assessments and computation tools are becoming more important. Groundwater regional scale phenomena usually cannot be studied accurately using labora...
