The Chagan Lake Catchment is located in the midwest of Songnen Plain, which a typical high fluoride groundwater area. High water has an important impact on economic development and ecosystem stability Lake. In this study, spatial distribution characteristics influencing factors fluorine are discussed by using hydrochemistry mathematical statistical analysis. study area was characterized as Na+-...

Umm Er Radhuma Aquifer (UER) is the most important groundwater aquifer in Saudi Arabia, extending over 1.6 M·km2 eastern part of Arabian Peninsula, forming main throughout Rub’ Al-Khali (RAK). Groundwater salinity increased from west to east, reaching more than 27,000 mg/L near border with United Arab Emirates, where a Na+-Ca2+Clˉ- water type dominated. Gibbs diagrams indicated that dissolution...

Introduction: The Mars Exploration Rover Opportunity has obtained chemical and mineralogical data for exposed bedrocks at Meridiani Planum on Mars. In using these data to formulate a diagenetic model for the bedrocks, a clear distinction must be made between the primary inputs into the rocks and products of secondary processes. The chemical composition of the Meridiani bedrocks provides the mos...

Understanding the effect of flooding on groundwater quality is imperative for oasis vegetation protection and local ecological environment development. We used geochemical remote sensing inversion methods to evaluate effects flood recharge hydrochemical processes in Daliyaboy Oasis. Groundwater samples were collected from 30 observation wells study area before (PRF) after (POF) flood. Except sm...

Understanding root water uptake sources in agricultural systems is becoming increasingly important the sustainable management of resources under changing climatic conditions. In this work, a stable isotope approach was adopted to investigate accessed by apple trees two orchards growing different locations upper Etsch/Adige valley (Eastern Italian Alps). We tested general hypothesis that soil wa...

in the last decade, the water level of urmia lake has experienced a dramatically drop. although the causes of this lose have been investigated, the significance of groundwater supplies had not been concerned so much. in the present research, groundwater resources around the lake were explored as its water supplier. the number of wells and groundwater withdrawal has been increased because of cul...
