Abstract:
Diclofenac (DCF) is one of the most frequently detected pharmaceuticals in groundwater, posing a great threat to the environment and human health due to its toxicity. To mitigate the DCF contamination, experiments on DCF degradation by the combined process of zero-valent iron nanoparticles (nZVI) an...
Clogging mechanisms and preventive measures in artificial recharge systems
M Shahbaz Akhtar, Yoshitaka Nakashima, Makoto Nishigaki
2021, 9(3): 181-201. doi: 10.19637/j.cnki.2305-7068.2021.03.002
Abstract(1972) FullText HTML (775) PDF(158) Cited By (11)
Abstract:
Groundwater which occurs in fractured rock or porous aquifers or other geological weak zones such as faults and fractures is usually extracted via boreholes, hand wells or other sources such as springs. Water scarcity has become a severe problem due to many factors, such as an alarming increase in p...
Evolutionary trend of water cycle in Beichuan River Basin of China under the influence of vegetation restoration
Liang Zhu, Jing-tao Liu, Ming-nan Yang, Yu-xi Zhang, De-ping Wen
2021, 9(3): 202-211. doi: 10.19637/j.cnki.2305-7068.2021.03.003
Abstract(878) FullText HTML (361) PDF(54) Cited By (9)
Abstract:
To understand the influence of vegetation restoration on the water cycle in semiarid areas, the effects of vegetation restoration on evolution of the key elements of water cycle were clarified by analyzing the evolutionary trend of atmospheric precipitation, ecological consumption water, and surface...
Hydro-geochemistry of groundwater and surface water in Dschang town (West Cameroon): Alkali and alkaline-earth elements ascertain lithological and anthropogenic constraints
Yemeli Elida Joelle, Temgoua Emile, Kengni Lucas, Ambrosi Jean-Paul, Momo-nouazi Mathieu, Silatsa-Tedou Francis Brice, Wamba Franck Robean, Tchakam-Kamtchueng Brice
2021, 9(3): 212-224. doi: 10.19637/j.cnki.2305-7068.2021.03.004
Abstract(1053) FullText HTML (315) PDF(84) Cited By (9)
Abstract:
This study focuses on the sources of alkali and alkaline-earth elements based on the geochemistry of groundwater and surface water in Dschang concerning environmental and anthropogenic constraints. A comprehensive set of 50 samples from groundwater and surface water were analyzed by ICP-MS and proce...
Quantifying groundwater recharge and discharge for the middle reach of Heihe River of China using isotope mass balance method
Han Zhang, Zong-yu Chen, Chang-yuan Tang
2021, 9(3): 225-232. doi: 10.19637/j.cnki.2305-7068.2021.03.005
Abstract(671) FullText HTML (256) PDF(48) Cited By (11)
Abstract:
Quantifying the inflow and outflow of groundwater is essential to understand the interaction between surface water and groundwater. It is difficult to determine these elements in relation to groundwater recharge and discharge to the river, because they cannot be directly measured through site specif...
Numerical modelling of the dynamic process of oil displacement by water in sandstone reservoirs with random pore structures
Fei Gao, Feng Liu, Hua-jun Wang
2021, 9(3): 233-244. doi: 10.19637/j.cnki.2305-7068.2021.03.006
Abstract(631) FullText HTML (261) PDF(35) Cited By (4)
Abstract:
In order to maintain the production rate of a reservoir and improve the displacement efficiency, it is crucial to have an in-depth understanding of the process of oil displacement by water. However, with respect to the conceptualization of porous media of a reservoir, very limited efforts have been ...
Source identification of methane in groundwater in shale gas development areas: A critical review of the state of the art, prospects, and future challenges
Zhao-xian Zheng, Ling-xia Liu, Xiao-shun Cui
2021, 9(3): 245-255. doi: 10.19637/j.cnki.2305-7068.2021.03.007
Abstract(1031) FullText HTML (470) PDF(57) Cited By (5)
Abstract:
Shale gas exploration and development carry the risk of causing groundwater contamination and enhancing the greenhouse effect through methane leakage. Identifying the source of abnormal methane in groundwater of shale gas development areas is becoming a research hotspot in the fields of groundwater ...
Identification of suitable sites for open and bore well using ground magnetic survey
A Muthamilselvan
2021, 9(3): 256-268. doi: 10.19637/j.cnki.2305-7068.2021.03.008
