background: the aim of this study was to assess the effects of road deicing salt on the quality of the ground water resources in hamadan province during winter season. methods: water samples were taken monthly from thirty wells located around the hamadan-asadabad highway. the quality of well water was examined by measuring amount of sodium, chloride, total hardness, total dissolved solid, elect...

By coupling two commonly used computer programs, MODFLOW (McDonald and Harbaugh, 1988) and MT3Dms (Zheng and Wang, 1998), the SEAWAT program was developed to simulate variable-density, transient ground-water flow in three dimensions. Freshwater head and salt concentration are used as the two principal dependent variables. Major improvements from the previous version of SEAWAT include (1) reform...

Freshwater-seawater (FW-SW) temperature contrasts widely exist in natural coastal aquifers. The significant effects of thermal forcing on water flow and salinity distributions for homogeneous aquifers have been demonstrated recently, however, the impact heterogeneous remains unclear. This study conducted simulations variable-density flow, heat salt transport with Monte-Carlo realizations log-no...

In the fertile Ganges-Brahmaputra-Meghna (GBM) delta, which spans boundary from West Bengal in India and Bangladesh, availability of freshwater is crucial to subsistence livelihoods protected ecosystems. Controlled by large tides widely variable river discharge, delta experiences rising salinity salt intrusion, as well seasonal flooding during monsoon. Future climate change projected increase r...

Abstract A series of experiments were carried out to evaluate and analyze the damage mechanism carbonate reservoir in Shunbei No.2 Area, Xinjiang, China. According analysis lithology physical properties, combined with fluid characteristics environmental characteristics, potential factors formation core analyzed. The is as follows: solid phase particle intrusion blockage, stress sensitivity stro...
