Owing to population growth and water demand, coastal aquifers all over the world are over–pumped, resulting in serious problems such as saltwater intrusion. So, in these conditions, assessing the groundwater system’s vulnerability and finding areas with saltwater intrusion potential are vital for the better management of aquifers. In this study, AHP-GALDIT was applied to saltwater intrusion vul...

Abstract Large-scale studies of the spatial and temporal variation groundwater drought status require complete inventories levels on regular time steps from many sites so that a standardised index can be calculated for each site. However, are often measured sporadically, include missing or erroneous data. A flexible efficient modelling framework is developed to fill gaps regularise data in such...

Background: This research aims to measure and study spatial changes, and the reason behind the increasing nitrate content in water wells in the Central District of Khodabandeh County in the Zanjan Province. Methods: The nitrate and nitrite content, electrical conductivity, dissolved oxygen, temperature, total hardness and pH were measured at 40 sampling stations in the study area. The obtained...

A research has been undertaken studying pesticide losses from areas with intense agricultural and horticultural productions such as vegetables, cotton, pot plants and flowers, taking grab and composite samples including using passive SPMD samplers in ditches, creeks, rivers and groundwater, in addition to greenhouse and imported products. Pesticides were frequently found, occasionally in high c...
