Abstract Porous and fractured aquifers exist in the area of Hurghada, Eastern Desert Egypt, whose recharge processes through common flash floods are not identified. Hydrochemical parameters, stable isotopes 18 O, 2 H tritium floodwater groundwater were applied subject to study. Additionally, He investigated deep wells faulted zone at Abu Shaar Plateau. 3 activity all sampled points lies below d...

Hydrochemical assessment of the freshwater lakes provides important insights into sources dissolved ions, geochemical processes, and anthropogenic activities taking place in environment. This study focuses on hydrochemistry water quality Kupinde Lake, Karnali Province, Nepal. Surface samples were collected from 24 different locations lake October 2021 analyzed for 18 physico-chemical parameters...

methane is one of the important greenhouse gases that contribute to a rise in global mean surface temperature. aquatic environments are postulated to contribute > 50% of the total global methane (ch4) flux to the atmosphere (de angelis and lilley, 1987). dissolved methane concentration in surface waters was measured from january to december 2008 at two selected sites upper reaches (ongc bridge)...

the objective of this study was to explore the microbial community diversities and the relationships between microbial community compositions and hydrochemical factors in nitrate contaminated groundwater of hun river alluvial plain. the method of polymerase chain reaction (pcr)-denaturing, gradient gel electrophoresis (dgge) gene fingerprints combined with canonical correspondence analysis（cca）...

Anthropogenic habitat transformations involving changes in hydrologic conditions the peatlands of eastern Poland contribute to disappearance sites numerous relict plant species. The study aimed verify whether chosen for reintroduction endangered species Salix lapponum had been well selected by analyzing parameters and determining their values may long term have a significant impact on functioni...
