A multi-objective optimization approach to groundwater management using genetic algorithm
Management of groundwater resources is very important for regions where freshwater supply is naturally limited. Long-term planning of groundwater usage requires method-based new decision support tools. These tools must be able to predict the change in the groundwater storage with sufficient accuracy, and must allow exploring management scenarios with respect to different criteria such as sustainability and cost. So,...

Monitoring trends of nitrate, chloride and phosphate levels in an urban river
Concerns for the river environment in Malaysia are highlighted. There had been occurrences of inadequate supply for water in big cities and unexpected floods over the last few years. This paper discussed the results of ‘clean-up’ efforts of Gombak River which passes through several industrial areas and the City of Kuala Lumpur. The trends in the levels of nitrates, chlorides and phosphates present in the...

Mapping of lineaments for groundwater targeting in the basement complex region of Ondo State, Nigeria, using remote sensing and geographic information system (GIS) techniques
Sustainable groundwater supplies in the terrain underlying by crystalline basement rocks require lineament analyses for proper sitting of boreholes. This study was carried out to illustrate the application and importance of Remote Sensing and Geographic Information System (GIS) techniques for efficient groundwater resource exploration and management. The study demonstrates the use of LANDSAT 7 ETM+ imagery, ASTER...
