Seawater intrusion represents a high risk for the water supply, agriculture and industry activities in lower Seybouse region of North-Eastern Algeria. In order to analyze this risk, three-dimensional model was developed using MODFLOW MT3DMS codes predict seawater coastal aquifer. The application indicates that groundwater withdrawals result continuous decrease level an increase chloride concent...

The extensive interest in sustainable water management reflects the extent to which global landscape has changed past twenty years, is a natural development of changes resources and an increase level imbalance between supply demand. In this paper, simulation model based on system dynamics (SD) methodology was developed aid efforts semi-arid region. Six policy scenarios were used study, analyze,...

Rapid infiltration following precipitation may result in groundwater contamination from surface contaminants or pathogens. In fractured rock, can migrate rapidly to points of withdrawals. contrast the temporal availability quality chemical indicators, meteorological and level observations are available real-time estimate time-varying recharge, which act as a surrogate identify periods rapid tha...
