this study will evaluates climate change impacts on groundwater resources in hamadan-bahar alluvial aquifer in the west of iran. different climate models are weighted in the basis of their ability in predicting monthly observed climate data in the base study period (1970-2000). with respect to climate models weights and their predictions, precipitation and temperature changes in 10, 50 and 90 p...

Abstract. In the context of changing climate and increasing water demand, large-scale hydrological models are helpful for understanding projecting future resources across scales. Groundwater is a critical freshwater resource strongly controls river flow throughout year. It also essential ecosystems contributes to evapotranspiration, resulting in feedback. However, groundwater systems worldwide ...

This paper presents some simulation–optimization models for groundwater resources management. These models couple two of the most successful global optimization techniques inspired by swarm intelligence, namely particle swarm optimization (PSO) and ant colony optimization (ACO), with one of the most commonly used groundwater flow simulation code, MODFLOW. The coupled simulation–optimization mod...

Environmental modelling workflows are often tedious due to heterogeneity of data sources, types and formats. This paper discusses how a software framework based on Open Geospatial Consortium (OGC) standards may facilitate the workflow steps and improve their flexibility by supporting data access, processing, and decision-making. The software framework is designed based on OGC standards, which c...
