This paper introduces a surrogate model to identify an optimal exploitation scheme, while the western Jilin province was selected as the study area. A numerical simulation model of groundwater flow was established first, and four exploitation wells were set in the Tongyu county and Qian Gorlos county respectively so as to supply water to Daan county. Second, the Latin Hypercube Sampling (LHS) m...

Groundwater pollution due to anthropogenic activities is one of the major environmental problems in urban and industrial areas. The present study demonstrates the integrated approach with GIS and DRASTIC model to derive a groundwater vulnerability to pollution map. The model considers the seven hydrogeological factors [Depth to water table (D), net recharge (R), aquifer media (A), soil media (S...

Groundwater resources as one of the most important sources of water needed for agriculture, industry and drinking is important, that are encountered With different risks such as level fall, reduced feed rate due to lack of rainfall and contaminants normal and abnormal. This study was conducted in Garmsar alluvial plain in Semnan province. According to the research purposes, process and effect o...

Artificial recharge of urban aquifers with stormwater has been used extensively in urban areas to dispose of stormwater and compensate for reduced groundwater recharge. However, stormwater-derived sediments accumulating in infiltration beds may act as a source of dissolved contaminants for groundwater. Concentrations of hydrocarbons, heavy metals, nutrients and dissolved oxygen (DO) were monito...

In the last decade, various aspects of groundwater resource depletion have gained a special place among water sector experts and decision makers. Research in this area is relatively new in most parts of the world. Groundwater depletion, which has been in a concerning state for most plains in Iran in recent years, has various consequences which impede sustainable development. One of the most imp...

Abstract A 10-yr simulation of shallow groundwater table (GWT) depth over a temperate region in northwestern Europe, using physics-based integrated hydrological model at kilometer scale, exhibits strong seasonal cycle. This is also well captured terms near-surface soil moisture anomalies, terrestrial water storage and GWT anomalies from observations the region. The modeled monthly anomaly stati...

Groundwater recharge from rainstorms can be vital for regional water resources. With the expansion of the need for more water in some specific regions under global climate change, groundwater is being pumped at a far greater rate than it can be naturally replenished. Considering that excess rainstorms could be utilized for groundwater recharge to lessen the declining tendency of regional ground...

Regarding to increased use of groundwater resources, it seems necessary to have more accurate knowledge of characteristics of aquifers in order to improved usage and accurate management of these resources. In this study, we simulated groundwater flow of Qazvin aquifer usingVisual MODFLOW model, collecting data and statistics, as well as using different studies. The simulation model has operated...

Groundwater resources in Arsanjan plain provide water for agriculture, industry, and human consumption. Continued agricultural development in this area needs to additional groundwater resources for, particularly during of drought periods, and effects on the quantity and quality of ground water available. The purpose of this study is to evaluate water level changes in the aquifer of Arsanjan pla...
