Quantitative changes in groundwater and crises resulting from uncontrolled water extraction have turned water resources management into one of the supply-demand dilemmas in arid regions. The present study evaluated the quantitative situation of water resources in the Ardestan Plain adjoining the Ardestan desert by using the MODFLOW mathematical model. Simulation of groundwater flow in the stead...

Abstract Stable isotope composition of ?2H and ?18O was investigated in the water resources Shwan sub-Basin northeast Iraq. The study objects conceived possible factors that affect stable isotopes’ precipitation additionally to achieve information concerning recharge processes estimate groundwater sources. In this study, four samples were collected at area for 2020–2021 hydrological year. Thirt...

Understanding the groundwater chemical regime on irrigated lands is relevant for assessing hydrogeological and reclamation processes. Water chemistry, natural climatic conditions, drainage characteristics define complex hydrochemical connections which are formed between irrigation waters, soil, water of unsaturated zone groundwater. This research paper presents results studies seasonal changes ...

The contributions from terrestrial water sources to sea-level rise, other than ice caps and glaciers, are highly uncertain and heavily debated1–5. Recent assessments indicate that groundwater depletion (GWD) may become the most important positive terrestrial contribution6–10 over thenext 50years, probably equal in magnitude to the current contributions from glaciers and ice caps6. However, the ...

In the present study, a total of sixty groundwater samples, twenty each for pre-monsoon, monsoon and post seasons 2018, were collected from selected locations in Mewat district Haryana, India. Electrical conductivity (EC) was measured at site dissolved solids (TDS) estimated. Samples analysed anions (chloride, sulphate, bicarbonate) cations (calcium, potassium, magnesium, sodium). Multiple regr...

during recent years oil products has decreased because of growing population and increasing demand to oil products and decreasing of crude oil extraction at compare to export. however, to achieve suitable levels of production, the use of improved technologies should be considered. another way to prevent the evaporation and leakage from oil storage tanks and their products are using of storage t...

Abstract Water is an important factor that affects local ecological environments, especially in drylands. The hydrological cycle and vegetation dynamics Central Asia (CA) have been severely affected by climate change. In this study, we employed data from Gravity Recovery Climate Experiment (GRACE), Global Land Data Assimilation System (GLDAS), Evaporation Amsterdam Model, Research Unit to analy...
